What is vacuum casting? 

Polyurethane vacuum casting is a molding process for duplicating plastic products by pouring liquid polyurethane/resin into silicone mold under vacuum condition, and solidifying in oven.  It’s one of a great ways to make high quality plastic prototypes and small quantity of parts. 

Advantages Of Vacuum Casting:

• Time and cost are significantly cut down compared to conventional mold making.


• Choose from a wide range of plastic types for the most optimal suitability.


• Colors & Textures can be cast directly to the vacuum casting parts or painted afterward.


• Rubber parts, Over-molding and Insert molding are available.


• Can do many complicate features that CNC machining can’t achieve.
