Vacuum forming (VF) is a widely used technique for efficiently creating consistent copies of parts from thermoplastic sheet material.
A master 3D mold is created with the desired exterior contours. These molds must be flat-bottomed to seal tightly to the VF machine bed. They are vented with pin-holes placed in concave details, inside corners/edges to improve mold's detail reproduction.
​
During the forming process, the mold is is anchored to the VF bed. The thermoplastic sheet is heated, softening it, and drawn down upon the mold. Immediately after, a two-stage vacuum draws the soft sheet against the mold details through the VF bed. When details optimize, the raw part is complete, removed and trimmed to the desired shape.
