Vacuum Forming Company | API - Heavy Gauge Thermoforming

Vacuum forming is the process of taking large sheets of plastic, heating the sheets to a temperature that makes them pliable, then using a vacuum to remove all of the air out from between the heated plastic sheets and a pre-made mold. Depending on the type of material used, vacuum forming can be performed rather quickly.

Vacuum / Thermoforming - TJ Lawson Design

Vacuum forming is where a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum. This process can be used to form plastic into permanent objects. Normally draft angles are present in the design of the mold to ease removal of the formed plastic part from the mold.

What is Thermoforming | Vacuum Forming | Pressure Forming .

Thermoforming is a plastic fabricating process which involves heating sheet plastic and forming it over a male or mold. The two basic types of thermoforming processes - vacuum forming and pressure forming - and derivative processes, such as twin sheet thermoforming, make plastic thermoforming a broad and diverse plastic forming process.
