Mastering Vacuum Forming

Vacuum forming is a widely used plastic molding technique that involves heating a polymer sheet until it becomes pliable, then applying vacuum pressure to shape it over a pre-designed mold.

How Vacuum Forming Works

To create a vacuum-formed product, the plastic sheet is first placed into a frame and heated until it becomes flexible. Once the material is ready, it is positioned over a pattern, and a vacuum is applied to suction the material tightly over the mold, creating the intended shape.

Once molded, the formed part is set aside to cool before trimming the excess plastic. The final product is then trimmed to remove unwanted material and finished for distribution.

Industries Using Vacuum Forming

Vacuum forming finds its benefits in markets such as aerospace for creating customized plastic parts. Some typical products made using vacuum forming include:

• Automotive parts


• Plastic packaging


• Healthcare packaging


• Store signage
