In the Vacuum Forming process, a single sheet of extruded plastic is heated to a softening point at which time vacuum (14.7psig) is applied to pull the sheet over a male tool, or into a female tool. Vacuum Forming is the most basic of the three thermoforming processes. This is generally due to the demand for low cost tooling, design flexibility, and shorter lead times. Since the cosmetic side of the part is on the non-tool surface of the sheet, a wide variety of surface textures or printed features are available.
Advantages of Vacuum Forming:
- Low cost tooling
- Quick turn-around for parts
- Easy tool modification, if necessary
- Wide variety of materials, colors, and textures are available
