Vacuum forming

（重定向自Vacuum former）

Vacuum forming mold made from Aluminium (cavity) and Steel (frame)

A sheet of vacuum-formed plastic. The pieces needed (in this case parts for a model aeroplane) will need to be cut out of the sheet.

Vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum is formed into permanent objects such as turnpike signs and protective covers. Normally draft angles are present in the design of the mold (a recommended minimum of 3°) to ease removal of the formed plastic part from the mold.
