Rapid Prototyping is still a new technology for the fast production of single plastic components that are functional and close or identical to parts made in series, within a few hours.
One branch of this new technology is vacuum casting. A silicone mould is made based on a master model, which has been built with one of the new generative technologies or in a conventional way. Then the silicone mould is filled with a two-part polyurethane resin under vacuum.
About 50 plastic prototypes can easily be made without complicated and expensive steel moulds. The parts cannot be distinguished from conventionally made serial plastic parts. The check of “fit, form and function” can be done very quickly.
