Vacuum casting is the manufacturing process of creating parts thru silicon made mold. VC is generally preferred for low-volume production of parts and rapid prototyping. VC working concept is the same as injection molding, both use a mold, however, the manufacturing process differs significantly from injection molding. VC has a wide range of available materials (ABS, polypropylene, nylon, polycarbonate, flexible) to choose from with varying properties from plastics to flexible. VC produces parts with appearance, mechanical properties and surface finishes comparable to those made with injection molding. The detailed process steps are described below.

Pattern Making
A pattern is a physical part created out of the CAD data received from the customer. The pattern is either created by 3D printing or CNC machining.
