Vacuum casting, also known as silicone or polyurethane casting, is a process that replicates a master pattern using a silicone mold filled with a material such as polyurethane resin under vacuum.
Vacuum casting (also known as urethane casting) is an economical alternative to low-volume injection molding of plastic parts and can be used to closely simulate final molded parts or finished products. Generally, molds are made from silicone rubber and use CNC machining or SLA part as a master pattern. These molds duplicate intricate details and textures and give consistent finishes from one part to the next. You can get production-like results including mechanical traits, wall thickness, colors, and surface finishes.
