How Is the CNC Spring Forming Machine Beneficial for Manufacturers?

The importance of the coiled metal spring has only been growing since its invention in the 18th century. Heavy duty coiled metal springs are popularly used in items ranging from shocks in bicycles to even instruments for the aerospace industry. Much of the world’s springs are made by the use of manually operated machines based on the engineering designs of the late 19th century. However, backed by several advantages, companies are increasingly shifting their preference towards the CNC spring forming machine.

 

What Is The CNC Spring Forming Machine?

CNC or Computerized Numeric Control is a technology where digital commands are interpreted by a physical machine so as to perform specific precision manufacturing function. Like the modern CNC based wire bending machine and the pipe bending machine, the spring forming machine has a set of mechanical arms with strong iron based components that can precisely bend metal wires to make springs, based on the set of CAD/CAM commands that are provided to a connected computer.

 

Cost Efficiency Guaranteed

Compared to traditional spring forming machines, the modern CNC spring forming machine can directly save the cost of labor and transportation. In traditional manufacturing settings, companies are often required to outsource the spring production to another producer. But with the entry of affordable CNC based spring bending machines in the market, many modern equipment manufacturers already produce spring within their own facilities. This has allowed manufacturers to not just make their supply chain leaner but also reduce the overall production cycles. With this innovation, individuals and businesses can even set up their own new spring manufacturing plant at drastically lower prices compared to the traditional settings, without even requiring the installation of expensive furnaces.

 

Option to Mass Customize

One of the biggest advantages of the CNC spring forming machine is the added ability to manufacture different varieties of springs with the same machine. In traditional settings, tedious changes have to be made so as to manufacture different variety of springs. But, with the CNC, a mere change in the CAD/CAM command can easily allow the manufacturing of different diameter and size variants of springs as required along the next stages of production. In fact, the CNC spring forming machines can even exceed the capacity of production, compared to traditional settings.

 

Saving Manufacturing and Warehousing Spaces

The modern CNC spring forming machine can be adjusted even in tight spaces to manufacture springs as and when required. The highly rapid and efficient production of springs means that companies don’t need to spend their resources on maintaining enormous warehousing spaces for the springs, in the manner they would need to do for traditional industries. Hence, with the host of advantages offered by CNC, an investment in the CNC spring forming machines is indeed justified.

How to Choose The Right Injection Molding Machine?

In general, customers who have been in the injection molding industry for many years have the ability to judge and choose the right injection molding machine to produce. However, under certain conditions, the customer may need the assistance of the manufacturer to decide which specification of the injection molding machine to use, even if the customer may only have sample or idea of the product, and then ask whether the manufacturer’s machine can produce, or which model comparison Suitable for.

 

In addition, some special products may need to be equipped with special devices such as accumulators, closed circuits, injection compression, etc., in order to produce more efficiently. This shows that how to determine the right injection molding machine to produce is an extremely important issue. The following information is provided for reference only.

 

The important factors that often affect the selection of an injection molding machine include molds, products, plastics, molding requirements, etc. Therefore, the following information must be collected or available before making the selection:

 

  1. Mold size (width, height, and thickness), weight, special design, etc.
  2. The use of plastic types and quantities (single material or multiple plastic).
  3. The appearance size (length, width, height, thickness), weight, etc. of the injection molded product.
  4. Molding requirements, including a few, product quality, production speed and so on.

 

After obtaining the above information, you can follow the steps below to select the right injection molding machine:

 

  1. Choose The Right Type: Determined by the product and plastic models and series. Since there are many types of injection molding machines, it is necessary to determine exactly which type of injection molding machine or which series should be used to produce this product.

 

  1. Put It Down: Determine whether the “large pillar distance”, “die thickness”, “minimum die size” and “die plate size” of the machine are appropriate by the die size to confirm whether the die is released.

 

  1. Get Out: Judging from the mold and finished product “open mold stroke” and “travel mold stroke” is enough to allow the finished product to be removed.

 

  1. Locked Up: The “mold clamping force” is determined by the product and plastic. When the raw material is injected into the mold cavity with high pressure, it will produce a hold-up force, so the clamping unit of the injection molding machine must provide enough “clamping force” to prevent the mold from being opened.

 

  1. Shoot Full: Determine the required “shot volume” and select the appropriate “screw diameter” from the finished product weight and number of cavities.

 

  1. Shot Well: Some engineering plastics require high injection pressure and appropriate screw compression ratio design to have better molding effect. Therefore, in order to make the finished product shot better, the need for injection pressure and the compression ratio need to be considered when selecting the screw. .

 

  1. Shooting Fast: Confirmation of “injection speed”. Some finished products require high injection rate and rapid injection to stabilize molding, such as ultra-thin finished products. In this case, it may be necessary to confirm whether the injection rate and the injection rate of the machine are sufficient, and whether it needs to be matched with a pressure accumulator, a closed-loop control device, or the like.

 

After the above steps, in principle, injection molding machines that meet the requirements can already be determined. If you have requirement or need more information of energy saving injection molding machine, I recommend you to visit Multiplas Enginery Co., Ltd. – they specialize in manufacturing a wide range of injection molding machines.

Guide of Laser Cutting Machine: The Right Way to Find Laser Cutting Equipment

This type of capital equipment expenditure is a big deal, so fabricators should know what to ask to find the right fit.

 

Tailift Laser Cutter 

For most manufacturers, buying an industrial laser cutting machine is a major investment. It’s not just the initial price you pay, but the fact that the purchase will have a great impact on the entire manufacturing process. If the wrong equipment is chosen, you have to live with the decision for quite a long time. It is not unusual to see manufacturers keep a laser for seven to 10 years.

 

Do you know the best way to go about purchasing a laser cutting machine? Even if you currently own one, how long ago did you buy it, and what has changed since then?

 

This guide should help you in making a capital purchase decision that will drive your manufacturing operations to new heights.

 

What’s The Application?

Perhaps the real question is, “Should I even be buying a laser cutting machine?” For many reasons, investing in a different cutting system may make more sense for a company’s manufacturing activities. Investigating all available options can minimize any possible regrets in the future.

 

Depending on the part volume, a stamping press may deliver the lowest cost per part. When speaking of metal forming in a press, however, you also are talking about the need to invest in tooling. Stamping also presents the ability to perform multiple tasks, such as forming and tapping, as part of the production process.

 

A traditional turret punch press can cut out holes and shapes economically, but, again, it involves tooling. A punching machine also can’t match the production speeds of laser cutting machines. As with a stamping press, some forming can be done on the punch press.

 

A high-definition plasma system is good for thick materials and for applications in which the edge quality isn’t critical. An abrasive waterjet also is good for thick materials and for applications in which the metal can’t have a heat-affected zone, which is a problem with most thermal cutting methods. Both plasma and waterjet cutting systems cost less than laser cutting machines, but many times do not match the laser’s cutting speed. Of course, plasma cutting and waterjet systems can boost productivity with the use of multiple heads and the ability to cut stacked blanks; the application obviously would influence what exactly you need.

 

Do We Really Need to Invest in Laser Cutting?

A company that doesn’t have a laser cutting machine generally subcontracts the work to one or several job shops with that capability. This scenario doesn’t involve a lot of risk and can work if you have some flexibility with lead times.

 

But there will come that time when you have to ask yourself if it is time for the company to bring laser cutting in-house. This has to be considered even if the business relationship with the subcontractor is great.

 

How do you know if it is the right time to own a laser? Look at how much you are spending monthly for laser-cut parts. In the words of Henry Ford, “If you need a machine and don’t buy it, then you will ultimately find that you have paid for it and don’t have it.”

 

If the decision is made to bring laser cutting in-house, you may be put in a position where you need to justify why the investment needs to be made. The costs associated with subcontracting out the laser cutting are just the starting point for the justification. How much more productive will the manufacturing process be with in-house laser cutting? How does this affect lead times? From an expense standpoint, not only do you have the cost of the laser cutting machine, you have labor and consumable costs, such as laser cutting assist gas.

 

Figuring out these answers will give upper management or even a lending institution an idea about production savings and subsequent return on investment following the initial investment.

 

What Does It Mean to Control the Laser Cutting Process?

Other than monetary issues, when manufacturers offer reasons as to why they are looking at purchasing a laser cutting machine, they mention “control.” Ask yourself these questions to see if you fall into this category:

 

  • How many times have we lost business because of late delivery?
  • Have we ever had to reject parts because of poor quality?
  • How would it help our image if we had our own laser cutting capabilities?

 

Who Should We Buy the Laser Cutting Machine From?

As a manufacturer, you have numerous sources to purchase a laser cutting machine. There are dealers that specialize in used equipment and original equipment manufacturers that offer state-of-the-art cutting equipment and even refurbished machines that may not have the production process of new machines, but still can perform much more efficiently than machines of a similar age with no rework done to them.

 

Ask the OEMs questions about service availability. Today’s technology does not require as much maintenance, but when a machine goes down, you’ll want it back up and running as soon as possible. Also find out about parts availability and delivery. Again, a laser cutting machine that can’t cut because of a damaged part just doesn’t cut it.

 

Be aware that laser cutting machines from OEMs that are recognizable in the industry typically have higher resale values.

 

CO2 or Fiber Technology?

Two types of lasers currently make up a majority of the industrial market: traditional CO2 gas lasers and newer solid-state fiber lasers. CO2 lasers have been the workhorses of the metal fabricating industry for the previous two decades. These lasers operate by running electricity through a gas-filled resonator (which includes CO2) and using mirrors to focus and deliver the beam. In a fiber laser, banks of diodes are used to create the laser, and it is channeled and amplified through fiber-optic cable, similar to that used in the telecommunication industry.

 

The fiber laser, which made its debut around 2008, has lower operating costs and delivers higher cutting speeds than the CO2 laser. Early on the fiber technology could cut at these higher speeds only on thin materials, but with the advent of more powerful lasers, fiber lasers are demonstrating robust cutting speeds even in 0.5-in.-thick material. As a result, fiber laser cutters tend to be a popular choice, despite their higher price.

 

Also, fiber technology may open new opportunities for a fabricator. These machines can cut reflective material, such as brass and copper, whereas it is difficult for CO2 lasers.

 

Some applications still remain better suited to CO2 lasers, such as applications that require good edge quality on thicker or specialized materials. Also, some manufacturers may feel comfortable with CO2 technology because they’ve used it for several years, and the company has in-house maintenance expertise.

 

After the end of the warranty period, keep in mind that you will have to make a decision about ongoing maintenance. Are you comfortable relying primarily on the OEM for service, or do you like to be self-sufficient, perhaps relying on a third-party source for any maintenance? Because the fiber laser has fewer moving parts or mirrors when it comes to laser generating, unlike a conventional CO2 resonator, it will require less maintenance over its lifetime.

 

Will We Need Material Handling?

Choosing some level of automatic material handling equipment also is an important consideration. This is even more important today, primarily because of the significantly faster cutting speeds of the fiber laser technology.

 

That’s why it’s necessary to understand just how you will use this new laser cutting capability. Do you plan to run the laser only a few hours each day or multiple shifts? Based on the typical time to process a sheet of material, can your operator keep up with manually loading and unloading the laser, even if it has a second shuttle table? How important is minimizing the labor cost in the part production to making a profit and remaining competitive in your business?

 

Sometimes metal fabricators choose not to buy material handling automation immediately. If you choose this route, ensure that pallet systems or even an automated storage and retrieval tower can be added easily in the future.

 

Will We Need New Software?

In many instances, manufacturers are already using a software package that everyone is used to. Will that software be able to work efficiently with the new laser cutting machine, or will you be better off purchasing the OEM’s software? If the latter, what new capabilities come with the new software?

 

As more of the manufacturing world is talking about increased interconnectivity among machines and software systems, it behooves you to ask if the new software is capable of running other machines already in place on the shop floor. Additionally, it’s worth having a conversation as to how the laser might integrate into the company’s network. Laser cutting speeds aren’t the only thing increasing at an incredibly fast pace; collecting pertinent manufacturing information in the blink of an eye is leading to more timely and impactful decision making for manufacturers.

 

What Is the True Cost of Running the Equipment?

With such a large investment, a manufacturer needs to know at what level of efficiency the equipment is operating. You need to know more than just if the machine is running or not running. This is where equipment performance monitoring comes in.

 

It’s important for you to find out if software can measure the laser cutting machine’s overall equipment efficiency (OEE) in real time. If so, can the software be used for your other laser cutting machines, if you have them, so that you might discover “hidden capacity” where you thought there was none?

 

With the cost of about 1 percent of the equipment price, monitoring software can provide a 10 to 50 percent productivity gain with paybacks of less than four months.

 

How Will We Finance the Purchase?

While some manufacturers pay cash for a laser, the majority use some method to finance the purchase. Don’t assume that your bank is the best source for funding the laser equipment purchase. Look at other alternatives, including the OEM, many of which own their own financing arms.

 

Also, don’t assume you will receive better service if you choose the OEM’s financing option.

 

What’s Involved with Delivery and Installation?

Preparation is required for a successful delivery and installation. First, what type of foundation, if any, is going to be required? Second, the laser cutting machine has to be located in the right place in the facility, preferably away from harsh environmental areas. You also should have found the best location for the laser so that it contributes to an efficient flow of laser-cut blanks to downstream manufacturing processes.

 

For a lot of companies, the delivery of a new piece of major manufacturing equipment is a new experience. The company that supplied the laser cutting machine can answer your questions about shipping and rigging; they do this all the time.

 

What Can Be Done to Make the Purchasing Decision Easier?

Answering these questions and obtaining quotes based on the feedback can be used to narrow down the selection of the supplier of a laser cutting machine to two to three sources. From there you need to find the right model, ask the right questions during equipment demonstrations, and work toward an acceptable price. Remember, there are many important items to discuss during the final negotiation.

 

The purchase of such a machine can be an overwhelming task. That’s why it might make sense to join an industry association, such as the Fabricators & Manufacturers Association, to network with manufacturing peers to learn from them, or even seek out the assistance of someone that has been through or is familiar with this type of industrial equipment purchase. Such an effort likely would prove to be worthwhile.

 

If you have interest or requirement of laser cutting machines, I recommend you to visit Tailift Co., Ltd. – they are the world-famous fiber laser cutting machine manufacturer. You can find high quality, efficiency, and accuracy laser cutters at Tailift. Now, contact with Tailift for more details of laser cutting.

Straw Bans Stir New Business As Firms Leap To PLA Replacement

Taipei, Taiwan — The global movement to ban petroleum-based plastic straws has hit Taiwan’s plastics machinery sector.

 

For 33 years, Taichung-based Jumbo Steel Co. Ltd.‘s bread and butter has been machines that make polypropylene straws, cotton-bud sticks and lollipop sticks, making it particularly vulnerable to a downtown in demand for straws.

 

But now, the company is finding straw makers retooling: Interest in its 2-year-old line of machines for making straws from bioplastic polylactic acid is running high, said Vice General Manager Sandy Kuo, in an interview at the Taipei Plas trade show, held Aug. 15-19 in Taipei.

 

“This year, it’s very hot,” she said.

 

Jumbo has an installed base of 100 machines in the United States, with many used to supply big U.S. customers like McDonald’s and Starbucks, which has announced plans to eliminate single-use traditional plastic straws by 2020.

 

Jumbo Steel is finding U.S. firms interested in retrofitting existing equipment.

 

“We have a customer from Seattle we met for dinner. We got an order to convert three of his PP machines into PLA straw making machines,” Kuo said.

 

PLA straws, which can be made from renewable sources such as corn starch, cassava chips or sugar cane, are permitted under Seattle’s ban on petroleum-based plastic straws and utensils that went into effect in July.

 

Founded in 1985, Jumbo makes about 170 machines a year in its Taichung factory in central Taiwan. It has sold to its machines in 120 countries.

 

Jumbo also makes machines that make and package those seemingly omnipresent bendable Tetra Pak straws.

 

“We’ve had a couple of inquiries to change our Tetra Pak machines from PP to PLA,” Kuo said.

 

Even though they represent but a fraction of plastic waste, PP straws have rapidly become a potent symbol of ocean pollution.

 

The Taiwanese Environmental Protection Administration has been especially aggressive.

 

Starting next year, food and beverage stores will not be able to provide plastic straws for in-store use, and in 2020, they will be banned from providing free straws. By 2025, fines will be levied for carryout use, and by 2030, they will be completely banned.

 

Plastic bags, beverage cups and utensils will be subject to similar rollout bans, with full bans slated for 2030.

 

One drawback industry officials point out: PLA costs three times as much as PP.

 

And PLA won’t break down until it has been exposed to the air for six months.

 

“PLA isn’t as environmentally friendly as many people think,” said Zen-Wen Chiou, vice president of the Plastics Industry Development Center in Taichung, which runs Taiwan’s only ISO-certified lab for PLA testing — a 180-day process.

 

As well, there can be recycling challenges, he said.

 

While PP retains 80 percent of its original strength after being recycled 20 times, PLA quickly degrades after being recycled two or three times, Chiou told Plastics News at the center’s Taichung offices.

 

“PLA shouldn’t be reground, but should be composted,” Chiou said.

 

There are environmental costs to shipping PLA, too, he said, with Taiwan importing most of its PLA from the United States, Chiou said.

 

But at the show, Kuo was in a more buoyant mode, saying she was close to closing a deal on four PLA machines with Taiwanese buyers.

 

“The market is very good,” she said.

 

The mood was decidedly pragmatic at the small booth of the Taiwan Plastics Industry Association, the island’s trade organization for processors. They’ll adapt to the decline in single-use plastics items, officials predicted.

 

“The domestic market for [one-use plastic items] isn’t that big, so those manufacturers will export to other countries,” Deputy Secretary General Hsu Chen said.

The Different Types of Plastics and How they are Recycled

It’s in bottles, containers, wrapping, and other everyday items. Plastic is as versatile as it is recyclable. By recycling the plastics you use every day, you can reduce your impact on the environment and help businesses cut costs. However, not all types of plastics are created equal. The number within the recycling symbol on plastic containers provides a wealth of information about their safety, biodegradability and recyclability. Here’s a 101 of what these various SPI codes mean.

 

  1. PETE or PET (Polyethylene Terephthalate)

Commonly found in beverage bottles, perishable food containers and mouthwash, clear PET plastics are generally considered safe, but can absorb odors and flavors from foods and liquids stored in them. Most recycling programs accept this plastic. PET plastics are recycled into carpet, furniture, and fiber for winter garments.

 

  1. HDPE (High Density Polyethylene)

HDPE is another commonly recycled plastic deemed safe. HDPE products have a very low risk of leaching into foods or liquids. You’ll find this plastic in milk jugs, yogurt tubs cleaning product containers, body wash bottles and similar products. Many children’s toys are also made from HDPE. Recycled HDPE is made into pens, plastic lumber, plastic fencing, picnic tables and bottles.

 

  1. V or PVC (Polyvinyl Chloride)

Found in food wrap, plumbing pipes, tiles, windows and medical equipment, PVC is seldom recycled. PVC plastics contain harmful chemicals linked to a variety of ailments, including bone and liver diseases and developmental issues in children and infants. Keep PVC items away from foods and drinks. Specialized programs recycle PVC into flooring, paneling and roadside gutters to name a few.

 

  1. LDPE (Low-Density Polyethylene)

More recycling programs are beginning to accept LDPE plastics. A very clean and safe plastic, LDPE is found in household items like plastic wrap, grocery bags, frozen food containers and squeezable bottles. Recycled LDPE is made into such items as garbage cans, paneling, furniture, flooring and bubble wrap.

 

  1. PP (Polypropylene)

Another safe plastic, PP is quite sturdy and found in Tupperware, syrup bottles, medicine bottles and yogurt containers. PP is recycled into heavy-duty items like pallets, ice scrapers, rakes and battery cables. Many recycling programs accept PP.

 

  1. PS (Polystyrene)

An easily recognizable plastic, PS or Styrofoam is found in beverage cups, insulation, packing materials, egg cartons and disposable dinnerware. Styrofoam is notorious for leaching and poor recyclability, though some programs may accept it. PS is recycled into various items including insulation, school supplies and license plate framing.

 

  1. Miscellaneous Plastics

SPI code 7 is a potpourri of plastics, one of which is polycarbonate. Sunglasses, computer casing, nylon, compact discs and baby bottles may contain #7. These types of plastics are hard to recycle and contain the toxic chemical BPA, a dangerous hormone disruptor that can cause health problems. Plastic #7 is primarily recycled into plastic lumber and specialized products.

 

A professional plastic waste recycling and reproducing machinery turn-key plant manufacturer – KOWIn continuously dedicates to the research & development and marketing of various types of plastic recycling machines for a long period. They can provide high efficiency recycling machinery and help customers recycle plastic waste and reproduce into final products.

Guide of Surface Grinder: How Does Surface Grinding Machine Works and Its Evolution

Surface grinding is an abrasive process. It involves securing the object to a device that will hold it in place (a chuck) before slowly moving the object’s surface across a grinding wheel that’s spinning really fast. This will generate a flat plane wherever the machine comes into contact with the object. It also gives the object an even finish. The longer the wheel spends working on the cutting depth, as well as using a surface grinding wheel with a higher grit count will further improve the surface’s finish. By slowly increasing the depth of the cut the machinist will be able to achieve these things.

 

Introducing the Surface Grinder

The surface grinding machine is the most common type of grinding machine found in any shop. You can actually compare it to milling cutter that has multiple teeth but the surface grinding machine has a grinding wheel, which makes it an abrasive cutting tool. The wheel is used to remove really small pieces of metal (known as swarf). It works because the wheel is made up of thousands of cutting edges.

 

These surface grinding tables are used for several different purposes including removing excess material. They work really well on very hard materials (i.e. steel, diamonds) to produce a very high quality finished surface.

 

How a Surface Grinding Machine Works?

The surface grinding machine’s chuck moves back and forth once the table has raised the object so that it’s slightly deeper within the wheel. There are intervals that can be set (i.e. 0.001 inches / 0.0254 mm) with each pass. As the grinding wheel rotates with its abrasive particles small amounts of the object’s material will be removed each time in order to create a flat surface. For this reason, the surface grinding process is usually a finishing step that’s designed to bring an object to a certain tolerance but the procedure is often followed up with a polishing procedure during the grinding-and-lapping process.

 

Evolution of the Surface Grinder

Over the course of time, the surface grinding machine has evolved. Today there are even some machines that are ergonomic, as well as those that are portable. Computer Numerically Controlled (CNC) grinders are also available. Regardless of the type of machine you choose to use, it will be controlled by a computer interface today.

 

Materials Used In a Surface Grinder

There are 2 types of abrasive materials that are used within the grinding wheel:

 

  1. Aluminum oxide is used whenever the materials that are being ground have a high ductility or the ability to permanently become deformed.

 

  1. Silicon oxide is used whenever the materials that are being ground have a low ductility.

 

Regardless of what type of material you’re grinding (i.e. steel, aluminum, glass) the machine’s abrasive grains will allow for a smooth finish. Usually these abrasive grains are coated with diamonds.

 

Types of Surface Grinders

A grinding wheel has a doughnut-like design. The hole in the middle slides down over the top of a metal rod (spindle). Today these machines are being made by lots of different manufacturers and so there are a lot of different models available to choose from. Nevertheless, they still use one of the following types of structure:

 

  1. A vertical spindle design has a spindle that’s pointing straight up and down. The grinding wheel itself lays flat on its face at the bottom of this spindle so that the wheel’s full width can be utilized in grinding the object. Typically, this type of design is used whenever working on larger panels or sheets of materials or whenever there’s a lot of materials that need to be quickly ground.

 

  1. A horizontal spindle design has a wheel that’s suspended over the table. Only the wheel’s flat, outside edge will come into contact with the object that’s being secured by the chuck. Thanks to the smaller grinding surface it’s possible to have great precision whenever you’re making a cut, which is why they’re typically used whenever small features (i.e. angles, profiles) are needed.

 

In the same way as there are 2 common types of spindles, there are also 2 common types of surface grinding machines, both of which only grind flat surfaces. These include:

 

  1. Planer grinders keep the grinding wheel in one place while the worktable around it is being moved, creating a reciprocating back-and-forth motion that can be controlled either manually or via a mechanic or hydraulic drive mechanism. The spindle that’s used to rotate the grinding wheel can be placed either vertically or horizontally.

 

  1. Rotary-type grinders have circular shaped worktables that revolve, as does the grinding wheel itself. They can be either vertical or horizontal.

 

If you have interest or requirement of surface grinding machines, I recommend you to visit Joen Lih Machinery Co., Ltd. – they are the leading manufacturer of surface grinder located in Taiwan. Their surface grinding machines are including semi-auto precision series, hydraulic series and auto down series. All Joen Lih precision surface grinding machines provide as standard equipment an electrically driven automatic lubrication system, they provide you the stable, safe and high efficiency surface grinding machines.

Swing Arm Clicker Press Maintenance

The most widely used die cutting machine in the world: the swing arm clicker press. If you’re reading this post, perhaps you own or manage one. With a good operator that has a routine or system, a swing arm clicker press can put out a lot of cut material in a small amount of time. It’s important to take care of your dies and make the right adjustments for that respective die, but it’s also important to keep your machine maintained for optimal performance, and protection of those dies.

 

Swing arm clicker presses are most frequently used with leather, footwear, gaskets, foam & rubber, plastics and textiles. Let’s say you just received a large sheet of rubber and have a die (or dies) that need to be cut with it. You go to turn on your machine and get it warmed up, adjust the height settings, do a test press, and notice that the machine is pressing down too hard. When this occurs, your order may need to be halted. This not only bottlenecks your process, but it sets back the recipient of the order, and if it happens mid-pressing, it could ruin your die.

 

Regular maintenance can avoid downtime, ruined dies, and even increase productivity. You can best maintain your machine by keeping it and its components clean. Debris and dust can clog filters and cause electrical components to lose connection.

 

Sometimes the issues can be something simple, or it could be something more serious like a cylinder seal replacement. All of them revolve around press pressure. Some issues we see include:

 

  • Electrical Component Failure, in particular, the pressure switch. When this component starts to fail, the press may start acting up and give you differential pressure between cuts.
  • Motor or pumps can go bad, which causes a loss of pressure. Perhaps you used to be able to cut on 5, now you need to set the press to 9 or 10.
  • Broken Hydraulic System. You may see air in the oil, holes or lose hoses, and filter issues.
  • Bad seals

 

If you have issue or requirement of swing arm clicker press, I recommend you to visit MINZ Inc. – they are the professional manufacturer of specializing in eco shoe cutting machines. Now, welcome to check out their website for more details of ECO hydraulic swing arm cutting machine.

Wide Web & Narrow Web Flexo Printing: Which is Better?

In today’s competitive environment, printers need to be as competitive as possible. To be competitive, one needs to choose the right tool for the right job. Wide web flexo press and narrow web press machine both has its advantages and disadvantages. At the end of the day, it comes down to what your main goal is.

 

For instance, is your main goal to be as environmentally friendly as possible to save cost from pollution emission and to build up a good eco- friendly company image? Is your main goal speed since most of your job orders are very long runs? Is your main goal for printing labels at small quantity?

 

Printing Press Design

The primary difference between narrow web and wide web is more than just the printing width. Speed is another main difference between the two, wide web flexo press tends to run at speed above 300 meters/min, as for narrow web usually runs between 150 ~200 meters/min. The difference in press speed impacts the formulation of the inks being used. Web wide usually uses faster drying solvent when compared to narrow web. When ink viscosities on a wide web is usually around 25 secs, #2Zhan and narrow web typically are around 35 secs. The narrow web tends to transfer a thicker ink volume onto the substrate.

 

In terms of press design, wide web is dominated by the central impression design being able to hold the tightest and finest registration, and most narrow web press has a in-line design. This affected the drying designs where central impression often has in-between layer dryers and a final post dryer. As for in-inline design often only have in-between layer dryers and doesn’t have a final post-drying unit. Wide web typically uses chambered doctor blade inking system and narrow web uses fountain rollers inking system. Fountain rollers systems will cause ink to be more exposed to the open air. As result, to be more vulnerable solvent loss and pH variable due to the ink evaporation.

 

Selecting Printing Press Machine by Application

In general UV ink application are found more on the narrow web, as the cost of UV ink application is greater when compared to solvent and water-based ink application. In terms of press cost, where the higher cost curing systems needed to be added. In terms of the operating cost, where UV curing requires a lot more energy and the cost of the UV ink itself is higher. Therefore, UV application tends to be installed on the narrow web.

 

The benefit of UV ink is that it dries only under curing, where the photo-initiator within the ink goes through chemical polymerization under UV radiation. Therefore, very fine anilox could be used as the ink doesn’t plug the cells of the anilox, as result producing finer and sharper images. Another benefit of UV ink is that it does not contain solvents, in terms of VOCs emission it is much more friendly.

 

You Could Consider UV Narrow Web Press If…

  • Narrow printing width
  • End product requires higher quality images.
  • Order volume is relatively smaller.
  • More variable in print design
  • Printed product could be sold at a higher price.
  • Regulation that places high fees on VOCs emission

 

You Could Consider Solvent / Water-Based Wide Web Flexo Press If…

  • Wide printing width
  • End product doesn’t require top quality images
  • Large order volume
  • Less variability on print design
  • Printed product is more price sensitive
  • VOCs emission regulation is less mature

 

There is not an absolute better solution. Select a suitable press machine type based on the end application and the goals that you are trying to achieve.

What are Thermoforming and Vacuum Forming?

Thermoforming

The Thermoforming process converts plastic sheet into products using heat. It is a process where heated thermoplastic sheets are molded to conform the sheet to a mold and once the shape is formed and allowed to cool, it is trimmed to create a part or product.

 

Heavy-gauge thermoforming typically produces more “permanent” or end use types of products. Thick or heavy gauge thermoforming usually requires tooling specific to each part because the part size can be very large and parts are trimmed on CNC routers or die cutting presses.

 

Vacuum Forming

Vacuum forming consists of heating a thermoplastic sheet to make it pliable and then applying vacuum pressure between the mold surface and the plastic sheet to remove any trapped air so the sheet conforms to a male or female mold, depending on the characteristics of the part. The additional pressure can allow thicker gauge material to be formed with more intricate detail and sharper corners.

 

What Is The Difference Between Thermoforming And Vacuum Forming?

The difference between thermoforming and vacuum forming is that vacuum forming has the additional process where vacuum pressure is used to conform plastic to the mold during forming.

7 Reasons Why CNC Machining Wins Over Conventional Machining

In recent years, CNC machining has been steadily overtaking the traditional machining industry. One can see this phenomenon as computers replacing human minds, just less severe.

 

After all, the term ‘CNC’ literally means ‘Computer Numerical Control’. The technology was first introduced to reduce human effort and make production processes faster and better. At the end of the day, both CNC machining and conventional machining aim towards one goal — producing quality machined parts.

 

The major difference lies in their approach and the fact that one option requires manual labor while the other boasts 90% automation.

 

Thus, the recent shift of major manufacturing companies to utilize the power of CNC machining over convention methods does not come as a surprise. Industries like healthcare, military, and aerospace need precision parts with tolerances as tight as +/- .0005, which is very difficult to achieve with conventional machining. Perfection isn’t the only thing CNC machining offers, though.

 

Below are some of the major reasons why CNC machining is becoming everyone’s favorite child.

 

  1. Reduced Labor Costs; One Experienced Machinist for Multiple Machines

In the case of conventional machining, every machine needs a dedicated technician with experience, skill, and extensive knowledge of the machine in hand. In contrast, CNC machining is hugely controlled by a software program and requires very little human interaction apart from the initial set up and data feeding. CNC machining also demands less advanced training, further reducing the labor costs. With computers playing a major role, the chances of human error and compromised workplace safety are also reduced by a high percentage.

 

  1. Large Quantity; Highest Quality

Because it requires manual effort, conventional machining is mostly set for low volume, small-quantity projects. CNC lathes, however, are built to provide maximum accuracy whether they are tasked to produce a few dozen metal machined parts or thousands of them.

 

Their high-quality material gives them resistance to wear and tear, which is common with conventional machining. As a result, they can run 24 hours a day with timely but quick maintenance. Additionally, CNC machining utilizes advanced software, which can be updated regularly per specifications, to allow for the easy manufacture of super-complex parts.

 

CNC machines also come with automated cooling systems, reducing the chances of heat damage. Many advanced machine models come with built-in chip storage and a conveyor belt for chip management.

 

  1. Part Replication Is 100x Better

Built to control exact velocity and positioning, CNC machines can produce several thousands of 100% identical parts in a record time, a feat that is impossible to achieve with handheld or conventional machining. Machines can be programmed to apply the same cut or do the same finishing repeatedly without compromising on the quality of the machined part. Conventional machining, on the other hand, requires a skilled operator to manually place the tool at every step of the machining process, which obviously would take a lot of time and patience. And even with such dedication, variations are to be expected.

 

  1. No Prototypes Necessary

Prototypes are needed to simulate designs and map their feasibility. Before CNC, every manufacturer would chalk out actionable prototypes, test-run them, and then work on the machining process. When done manually, this whole routine usually took several days or sometimes even months. The introduction of CNC machines ushered in software programming wherein you could input your design and visually see if you could work with it under realistic scenarios. This means no extra expenses for prototype development, shorter production times, and a bare minimum labor cost.

 

  1. Ability to Develop Complex Parts

CNC machines can be reprogrammed and updated at any time, giving them the liberty to produce 3D, 4D or even 5D parts with ease. This allows for a smoother shift between regular CNC machined part production and complex part production if required. Additionally, the software can store designs, so you can revisit any desired shape or other design even faster.

 

  1. Major Eye for Specifications

CNC machining is designed to focus on precision; machines adamantly maintain the specifications provided by their operator. Throughout the production process, every step is visually tested to ensure the desired effect and dimensions.

 

  1. Works for Every Material Type

This is probably the biggest advantage CNC machining has over conventional machining. CNC machines can utilize almost every type of material, including metal, steel, wood, foam, or sensitive plastics.

 

CNC Machining Adaptability

Delivering top-of-the-line accuracy, precision, and speed for product quantities both high and low, CNC machining presents a highly beneficial choice for manufacturers across a variety of industries.
