Vacuum Forming

Vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mould, and forced against the mould by a vacuum (suction of air).

Vacuum Formed Plastics

An alternative to vacuum forming involves a continuous process where semi-molten polymer is formed between two corresponding rollers with male and female forming points. Geofabrics manufactures cuspates using both technologies.

There are several aspects that will determine the properties of the finished cuspate:

  • The polymer.
  • The additives.
  • The sheet thickness.
  • The shape and size of the cusp.
