What is plastics thermoforming?

polypropylene-pp-sheetMany plastics applications, especially sample or prototype parts, require thermoforming to form the plastic into unique shapes and sizes.

Thermoforming is accomplished in 3 steps:

  1. a plastic sheet is carefully heated to a pliable, stretchable temperature,
  2. the heated plastic is placed in a mold, then
  3. the individual pieces are trimmed to size.
