The kind of plastic used in Thermoforming can undergo through melting and freezing without changing its chemical state and it can be re-used again. The plastic sheet or film is heated between specialized heaters in order to form the product with its usual temperature range.

Then it is placed in a temperature regulated metal table or molder until it is cooled down. The plastic formed from the molder will be taken out of the sheet. Used or excess plastic sheets are being recycled in order to form new plastic products out of it.

This special procedure is being processed to form plastic used for computers, machines, and other special equipments for medical, electronics, and industrial products.

Thermoforming has two general process categories called the thin gauge and the so called heavy or thick gauge. Thin gauge is used for thin sheets of plastics and can be directly processed with regulated temperature.

Unlike the heavy or thick gauge, the plastic used there is thicker than the thin plastic sheets and it still need to cut into pieces before being processed.

Instead of using the regulated temperature for thin plastics sheets in order to form a product, the temperature is higher than the regulated temperature in heavy or thick gauge.
