Rapid prototyping silicones
For the preparation of a prototype from a 3D model
Silicone rubber moulds are often used to make prototypes before serial production. Stereolithographic masters are used to create silicone rubber moulds.
Silicone moulds are ideal for casting resins with good mechanical properties and can be used to present objects for study.
The mechanical and thermal properties of these resins are similar to those of the thermoplastic materials used in the production of the finished part. This means that prototypes are not only faithful reproductions of the original master, but can also be used for functional tests, and provide a valid basis for preliminary sample testing. For rapid prototyping applications, we supply transparent materials with a hardness of 42 shA in DRY and OIL BLEEDING versions (for increased resistance to particularly aggressive substances like PU resins). We also supply translucent silicone rubbers with low viscosity and high tear resistance for prototyping small, precision parts.
The key characteristics of these prototyping silicones are:
- high transparence for a clear view of the object inside the mould
- excellent mechanical properties
- excellent chemical compatibility with artificial resins like PU (polyurethan), epoxy, PES (polyethersulfone)
- accurate reproduction of details
- easy removal from the mould
- no shrinkage when cured
