Vacuum casting is an ideal technology to produce small end series in a short period of time, and at a relatively low cost.
Starting from an SLA model, which will get a master finish, a silicone mould is made. An average of 25-30 casting can made from one mould. The exact amount however, is depending on the characteristics of the requested material.
A wide range of known materials is available (PP, PE, ABS, rubbers,…). Casted parts can easily be finished and the technology makes it possible to make 2K models. By overmoulding parts you are not restricted to one specific material.
