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:
- Mold size (width, height, and thickness), weight, special design, etc.
- The use of plastic types and quantities (single material or multiple plastic).
- The appearance size (length, width, height, thickness), weight, etc. of the injection molded product.
- 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:
- 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.
- 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.
- 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.
- 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.
- Shoot Full: Determine the required “shot volume” and select the appropriate “screw diameter” from the finished product weight and number of cavities.
- 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. .
- 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.
