Procedures
1. Place the plastic sheet in window style clamping frames
2. Once the thermoplastic sheet is secured in the heating area, it is heated to forming
temperature using either heating systems
3. Forming temperature, depending upon specific material type, range from 120o
to 370o
Celsius
4. Operate the drape thermoforming, in which the plastic sheet is stretched over a positive
mold. Once the plastic seals against the mold edges, a vacuum is introduced pulling the
material tightly against the mold contour
5. Once parts are thermoformed, they must be trimmed from the initial thermoplastic sheet
