What is Vacuum Casting?

What is Vacuum Casting?

Vacuum casting is an advanced manufacturing process used primarily to produce high-quality plastic parts in small to medium quantities. It involves creating a silicone mold from a master model (often produced by 3D printing or CNC machining) and then casting polyurethane or other resins into this mold under vacuum conditions.

The vacuum environment removes air bubbles and gases during the casting process, resulting in parts with excellent surface finish, dimensional accuracy, and mechanical properties. Vacuum casting is widely used for prototyping, functional testing, and low-volume production in industries such as automotive, aerospace, consumer electronics, medical devices, and more.

Key Steps in Vacuum Casting

This method is ideal for functional prototypes, concept models, and end-use parts that require tight tolerances and excellent material properties.
