Usually we make a master model by SL and then apply whatever surface finish is needed to the master model. We then pour liquid silicone rubber around the master model in casting box. Once cured we split the silicone rubber mould and we can use it to cast up to 20 PU parts per silicone mould.
We can simulate a full range of thermoplastics and elastomers.
Vacuum cast prototypes can be colored and textured in the mould.
To produce high gloss clear parts we will normally use a CNC machined and polished Acrylic master model. Cast clear parts from Star-Prototype are of a very high quality.
