Vacuum casting is ideal for duplicating models. Starting from a master model, a silicone mold is created which is then used to duplicate parts made from polyurethane. Surface treatment is our passion and we can simulate any desired surface on the master models – this is then reproduced in the silicone tool during its creation. Using this technology, we can thus produce components that are indistinguishable from an original injection-molded part. High gloss, EDM texturing, graining, etc. – almost anything is possible. The perfect coloring of the casting resins in accordance with RAL, Pantone, NCS, or based on your sample, guarantees optimum results.
Design and functional prototypes for all applications cast from near-series material. Whether for displays, headlight glass, light guides, covers, plugs, multi-component components, housing shells or complete devices – with this technology virtually anything is feasible.
The final touch
We can use special painting techniques to treat the master models and duplicated parts in accordance with customer requirements. We finish the prototypes via EDM texturing, high gloss, special effects (metallic, silver, partial) or subsequent varnishing. Individual color samples or color requests (RAL, NCS, Pantone) are also no problem.

Particularly strict demands are placed on transparent molded parts such as displays, containers, light guides and lenses in terms of transparency, degree of gloss and light transmission. The cast resin 122 we use meets these requirements. Its approximate characteristic values compared to the series materials polycarbonate (PC) and Plexiglass (PMMA) are shown in the following table.
