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.
