Thermoforming/Vacuum Forming   2007-10-14 SCS Cases Thermo-formed/Vacuum-formed cases:  uses several different types of sheet plastic. ABS, polyethylene and polypropylene are the core case material. Tooling and product turn-around time is fairely quick and cost effective. Depending on the number of case being run, tooling can be made of wood or aluminum. This process starts with the sheet plastic material being heated and then drawn down over the case tool.
