Vacuum Casting is a casting process in which a liquid material is drawn into a silicone mold using a vacuum to create complex components. The liquid materials used for vacuum casting are elastomers such as plastic and rubber.
Vacuum casting is sometimes referred to as polyurethane casting or urethane casting as polyurethane resin, a type of elastomer, is used as the casting material. Vacuum casting is an economical alternative to injection molding for making plastic components as the production cost of vacuum casting is comparatively lower.
Vacuum casting is an excellent production process for batch production and other low-volume production jobs. Vacuum casting is heavily used in the FMCG and consumer product manufacturing as well as industrial electronics production.
