What’s the difference between vacuum forming, thermoforming, and other types of forming?


Thermoforming is a more generic term that includes both vacuum forming and pressure forming. Vacuum forming is the process of using atmospheric pressure to push a heated sheet of plastic down over a mold, thereby shaping it. Pressure forming is similar to vacuum forming, except compressed air is used in place of vacuum. This facilitates higher-definition parts. Our Vacuum forming machines get plastic out of the oven and onto the tool in approximately two seconds, thus allowing us to form detail typical of a pressure former.
