What is Vacuum forming?

Vacuum forming or thermoforming is the process of heating a sheet of plastic before stretching it over or into a single surface mould. The heated sheet is held against the mould by applying a vacuum between the mould and the plastic sheet.

Vacuum forming is one of the most common methods of processing plastic materials. Vacuum formed products can be found everywhere and play a major part in our daily lives.

What is the process?

  • A flat sheet of plastic is heated until pliable
  • The mould or tool is introduced with the desired profile
  • The plastic is forced over the mould
  • A cooling process takes place
  • The mould is retracted to leave the formed product
