“Parts can be produced in a wide array of materials to simulate most engineering plastics”
Masters from any source are used to produce silicon tools from which castings can be produced in a wide array of materials to simulate most engineering plastics.
We can produce Polyurethane (PU) castings in the following material simulants or properties: ABS, Polypropylene, Nylon, Glass-filled Nylon, Polycarbonate, TPE, Hytrel, HDPE, etc. Temperature specific materials, flexible materials with A Shore ratings as low as 30A up to 90A and D Shore ratings also.
Typical applications are endless; however here are just a few areas where we have produced PU parts where our competitors couldn’t: Medical remote control handset with gloss finish, functioning multi-coloured flexible keypad and integrated built-in over-moulded seal, to provide a pressure-tested watertight seal.
Under-the-bonnet common rail fuel system component, combining high accuracy stepped bores (±0.05mm) with a high temp requirement of 120°C and a resistance to fuel, oil etc. The components excelled in the tests coping with 14 Bar of pressure.
Chrome effect parts. Parts to represent chrome plating are achieved using a mirror gloss finish master and high temp PU castings which are subsequently vacuum-metalized
