What is Vacuum Forming?
This is a simplified version of thermoforming, whereby a sheet of
plastic is heated to a forming temperature, stretched onto or into
a single-surface mold, and held against the mold by applying a
vacuum between the mold surface and the sheet. The vacuum forming
process can be used to make most product packaging and speaker
casings. It is also used to fabricate car dashboards. The first
commercial manufacturer of vacuum-formed plastics was Robinson
Industries of Coleman, Michigan.
