Thermoforming

Thermoforming entails heating thermoplastic material, which is in a sheet form to a controlled temperature where the machine can alter the sheet of plastic to the shape of the mold. The pre-heated thermoplastic is shaped to the mold by vacuum, air pressure and direct mechanical force.

Once the sheet assumes the desired shape of the mold design, it is cooled and die cut. The finished part is then removed or ejected from the mold.

There are subtle advantages (and disadvantages) to using thermoforming over injection molding to create plastic containers. Polytainers closely examines the requirements of the container, including the customer's objectives, to select the most effective method to manufacture the component.
