Pressure Forming Manual
We have a very good manual that describes the process and uses of Pressure Forming.

Pressure Forming is a recent modification to a well known technology, vacuum forming.
In vacuum forming a heated thermoplastic sheet is clamped in place above the surface of the mould. The air between the sheet and the mould is evacuated forming the “vacuum” and atmospheric pressure (aboutl5 lb/in2 or 1kg/cm2) forces the sheet into contact with the mould, where it cools, solidifies, and is removed.
The same principle is employed in PRESSURE FORMING. The air between the mould and the heated sheet is evacuated, but this time compressed air at up to 100 lb/in2 (7kg/cm2) is used to force the sheet into contact with the mould surface where it cools and solidifies.
There is a further difference between the two processes and this relates to the type of mould. In vacuum forming, both male and female moulds are used; in PRESSURE FORMING, female moulds are almost invariably used.
Advantages of Pressure Forming
- Precise details and attractive appearance Ideal for Start Up Production Widest selection of Materials and Colours Large sizes are no problem High impact strength Various finishes and cuts can be applied
- Low Initial Investment
and no more expensive than Vacuum Forming
