Pressure Forming Plastic

Pressure forming can use more than triple the amount of air pressure than vacuum forming allowing the heated plastic to better adhere to the mold in the thermoforming machine.

Pressure forming plastic.

This provides the same quality edges of an injection molded product while using resources more efficiently and applying less stress to the product and machinery. This produces three dimensional parts with features and aesthetics such as detailed surface finishes and textures that rival more expensive processes. Pressure thermoforming is a plastic manufacturing process in which compressed air is used to push the back of the plastic sheet against the mold. To start we add a vessel on the opposite side of the sheet from the mold.

Each has its own advantages and this table will help you decide which plastic forming machine might be right for you. Vacuum pressure forming. Pressure forming uses both vacuum and air pressure to push the soft heated plastic more tightly against the mold giving the part sharp detail. Pressure forming plastic is an enhancement of vacuum forming making it one of the more advanced forms of thermoforming we begin the process as with vacuum forming.

Plastic pressure forming is an excellent alternative to injection molding or structural foam molding in many applications especially in runs of moderate volumes. Pressure forming can produce single wall parts. Thermoforming can use one of two processes vacuum forming or pressure forming.
