en.wikipedia.org/wiki/Thermoforming

Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that ...

Suck the air out of the vacuum former by switching on the pump. The plastic ( polystyrene) will press down over the mould as can be seen on the diagram. If your machine has a moveable plattern it is a good idea to raise it upwards into the hot sheet before the air is sucked out. 3. As can be seen from this diagram the plattern ...

Thermoforming has close similarities with Vacuum Forming except that greater use is made of air pressure and plug assisted forming of the softened sheet. The process is invariably automated and faster cycle times are achieved than in the Vacuum Forming process. Only thermoplastics sheet can be processed by this ...
