Next you actually drape the hot plastic sheet over the mold.

Thermoforming sheets kits. Thermoforming can range in complexity from manual operations to highly automated large scale ones. This causes the plastic that touches the mold to cool very abruptly and freeze onto the mold surface. The sheet is pulled into the mold with a vacuum.

Amorphous plastics like abs and polycarbonate generally have wide processing windows and good melt strength making them easy to thermoform. 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 tripped to create a usable product. When you remove the plastic from the oven the surface of the sheet will cool off very quickly so you do not have much time to actually form the material usually only seconds.
