Vacuum Forming
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...
Pressure Forming
In the Pressure Forming process, a single sheet of thermoplastic is heated to the softening point before pressure of up to 90 psig is applied to "force" the material into a female tool. With pressure and very intricate molds, highly detailed parts can be produced matching those made by injection...
