Plastic Extrusion Forming
- Pressure forming – used mostly for smaller volume runs, offers injection-molded quality and details. The pressure applied (up to 100 lbs/sq inch) makes it possible to obtain highly detailed parts and textured finishes. Advantages include sharp edges, undercuts, and other close-tolerance details.
- Thermoforming – is a common post-extrusion manufacturing process that heats a plastic sheet to a pliable temperature, forms it to a specific shape in a mold, and then trims it to create a whole new shape.
- Vacuum forming – more commonly known as vacuforming, is a simplified version of thermoforming, whereby a sheet of plastic is heated until it is soft, stretched onto or into a single-surface mold, and then held against the mold by applying vacuum between the mold surface and the sheet. The plastic sheet is, in essence, pressed to the pattern by atmospheric pressure.
The materials most suitable for these processes are cast acrylics, ABS, high impact styrene, high density polyethylene and pressed rigid PVC, which, at their optimum forming temperature, become thermoelastic.
