What is Vacuum Forming?

What is Vacuum Forming?

Vacuum forming is a type of thermoforming process used to create plastic parts. During the process, a plastic sheet is heated until it becomes soft and flexible, then vacuum pressure is applied to draw the material tightly against a mold, forming the desired shape. Once cooled, the formed part is trimmed and finished as needed.


Vacuum forming is a cost-effective and efficient manufacturing method that can produce high-quality plastic components with consistent results.
