Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mould, and trimmed to create a usable product. The sheet, or “film” when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mould and cooled to a finished shape. Its simplified version is vacuum forming.

The Thermoforming processes are:

  • Vacuum Forming.
  • Pressure Forming.
  • Plug-assisted Forming.
  • Twin Sheet Thermoforming.
