KESI-3D
VACUUM CASTING
Vacuum Casting Service

Vacuum Casting is a widely used process in rapid prototyping, typically used for building 10 to 50 pieces of functional prototypes out of broad range of polyurethanes and other polymers.

KESI-3D owns 5 sets of vacuum casting machines, which can cast prototypes with the max dimension up to 2200mm*1200mm *1000mm. 

We can accurately reproduce the prototypes with original color, over-mold, inserts molding, texture and geometries from the master model and components. These plastic castings will closely represent the mechanical properties of the intended production parts from a steel mold. One silicone mold can cast about 15 to 20 pieces of parts, depends on complexity, painting or original color, size and other factors in different parts. From machining a master part to casting PU parts usually only takes 7-10 days, or even  less.
