Vacuum forming is the simplest type of plastic thermoforming, that uses one mold and vacuum pressure to obtain the desired part geometry. It is ideal for parts that only need to be precisely formed on one side, such as contoured packaging for food or electronics.

Vacuum forming is a simplified version of thermoforming, where a sheet of plastic in various forms of High Impact Polystyrene Sheet (HIPS) for low impact products, or ABS for bathroom shower trays, and HDPE for exterior vehicle parts, plus various other types of vacuum formable materials) is heated to a forming ...

Additionally, since vacuum forming does not require expensive molds or tooling, it is a cost-effective option compared to other manufacturing processes like injection molding. Another advantage of vacuum forming is its versatility in material selection.
