Vacuum forming is a widely used thermoplastic molding method that involves heating a plastic sheet until it becomes malleable, then applying vacuum pressure to mold it over a pre-formed mold.

How Vacuum Forming Works

To produce a vacuum-formed product, the plastic sheet is first mounted into a frame and heated until it becomes soft. Once the material is ready, it is positioned over a mold, and a vacuum is applied to suction the material tightly over the mold, ensuring the required shape.

Once molded, the formed part is allowed to cool before trimming the excess plastic. The final product is then cut to remove unwanted material and prepared for assembly.

Industries Using Vacuum Forming

This technique is widely used in numerous industries, including packaging, to produce custom components. Some common products made using vacuum forming include:

• Automotive parts


• Plastic packaging


• Healthcare packaging


• Store signage

 

Benefits of Vacuum Molding

Vacuum forming is a fast method for producing custom plastic parts with minimal initial investment. Other key benefits include:

• Fast manufacturing process


• Low-cost tooling


• Versatile applications


• Lightweight materials
