We will make a master model by SLA or CNC milling process 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 we split the silicone rubber mold and we can use it to cast up to 20 PU parts per silicone mold.
UP4280 is our most popular ABS simulant; PX522HT is best for clear parts; UP8400 is our rubber simulant. All can be colored to any Panton Number or RAL.
Also we can simulate a full range of thermoplastics and elastomers.
We can have one material over-molded with another to simulate, for example, rubber over ABS, or opaque plastic over transparent plastic. It is also possible to over-mold threaded inserts. Painting and printing after casting is also common technology we used here.
Vacuum cast prototypes can be colored and textured in the mold.
To produce high gloss clear parts we will normally use a CNC machined and polished Acrylic master model by hand.It will need Cast clear parts from Star-Prototype are of a very high quality.
