The casting method of polyurethane allows you to have near-series prototypes and small batch series. After the primary model is moulded in silicon it is cast with polyurethane resin (PU).
The cast resin is selected according to the required material properties of the serial material. That way, highly transparent components, a combination of hard and soft material as well as insert parts from other material can be realized.
The output of the parts from the silicone form are dependent on the geometrical complexity and limits the number of possible duplicates. Typical batch sizes are 5-1000 units.

The process uses a liquid resin that is then poured into the vacuum chamber
Different manufacturers provide a variety of polyurethane resins with the most diverse material properties for the
vacuum-cast. By mixing in colour, the cast resin can be adjusted to your requirements. Also crystal clear cast
resins can be manufactured.
Due to the fact that there is such a great variety of material we can offer you a detailed consultation.
