Pressure formed parts are available in a large variety of colors materials and different textures utilizing common thermoplastic materials.
Pressure forming plastic.
Pressure thermoforming is a plastic manufacturing process in which compressed air is used to push the back of the plastic sheet against the mold.
Pressure forming produces parts that have crisper detail and sharper features than conventional vacuum formed parts.
This produces three dimensional parts with features and aesthetics such as detailed surface finishes and textures that rival more expensive processes.
Each has its own advantages and this table will help you decide which plastic forming machine might be right for you.
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.
To start we add a vessel on the opposite side of the sheet from the mold.
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 produces tight crisp features.
Vacuum pressure forming.
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.
Plastic pressure forming is an excellent alternative to injection molding or structural foam molding in many applications especially in runs of moderate volumes.
