For over 20 years we have placed a strong focus on vacuum casting using silicone molds.
During this time, we have accumulated extensive knowledge regarding the availability of various synthetic resins that are suitable for vacuum casting.

Our portfolio consists of approx. 70 standard materials. In addition, we offer production of components in so-called “special materials”.

These cover numerous applications:

  • Food-grade materials
  • FDA certification
  • Flame-retardant materials / FAR
  • UL 94 compliance
  • Thermally stable materials (up to 190°C)
  • Impact-resistant materials
  • Transparent components
  • Components with a diffuser additive

Unfortunately, component production using these special materials often involves a minor negative aspect that must be taken into account: While we can offer the production of 1,000 parts with standard materials from a single silicone mold, this is not usually possible with special materials. For example, the output may be limited to 10 to 15 parts when using a thermally stable material, depending on the geometry of your component. Your requirements for the component are the decisive factor here.

With our PU materials we try to get as close as possible to the customer's wishes – “1-to-1” to the original, as it were The aim is to meet as many requirements as possible with the chosen material. Unfortunately, in terms of the component properties, parts produced in PU are always a compromise compared to those manufactured in injection-molded thermoplastics. We would be delighted to discuss your needs and advise you about the best solution for your prototype.

Thanks to its high thermal stability, the components retain their shape even at 190°C.
