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.
Pressure forming plastic.
Pressure forming produces parts that have crisper detail and sharper features than conventional vacuum formed parts.
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 uses both vacuum and air pressure to push the soft heated plastic more tightly against the mold giving the part sharp detail.
Pressure thermoforming is a plastic manufacturing process in which compressed air is used to push the back of the plastic sheet against the mold.
Thermoforming can use one of two processes vacuum forming or pressure forming.
Pressure forming plastic produces tight crisp features.
To start we add a vessel on the opposite side of the sheet from the mold.
Pressure forming can produce single wall parts.
Each has its own advantages and this table will help you decide which plastic forming machine might be right for you.
This produces three dimensional parts with features and aesthetics such as detailed surface finishes and textures that rival more expensive processes.
