Vacuum Casting Process

Vacuum casting is a follow-up procedure used in conjunction with a stereolithography model and a silicon form that allows us to produce polyurethane castings models quickly and cheaply. Depending on the complexity of the prototype 15 to 30 pieces can be created using one silicon form.

A silicon form is placed inside a vacuum chamber and is filled with the polyurethane through a feed channel. During this process, the vacuum sucks out any air trapped inside the silicon form, thus making sure that no air bubbles form in the finished prototype. This allows the production of high-quality, complex prototypes for numerous purposes such as functional tests, fittings or near series tests.

Using our machines we can cast two and three component parts using the vacuum casting procedure.

The variety of polyurethanes available is so great that almost any material used in the finished product can be imitated using this process.
