What is plastic thermoforming?

Plastic Thermoforming is a manufacturing process used to heat a plastic to a temperature where it can be shaped in a mold. After the plastic form has hardened, it is trimmed to finish the thermoformed product or component.

For prototypes or samples, a smaller machine can be used to stretch small heated plastic sheets to a mold by use of a vacuum. In batch runs, larger machines handle the process of heating, shaping, and trimming which allows for continuous high-speed production. The advantages of thermoforming include low cost and fast turnaround times, lending itself to be a great choice for developing prototypes. It also serves higher volume production by offering the ability to make in-production product changes or improvements.

Plastic Thermoforming OEM Applications

We’ve thermoformed custom OEM products ranging from heavy-duty plastic engine covers, to lawnmower tops, to airflow vents, to medical equipment coverings and containment systems for the U.S. Department of Defense. Heavy gauge polymer products will survive harsh environments and give long maintenance free service life.
