Casting here at Timothy Roe Fine Jewellery has been an area of expansion over the last 18 months. We changed from having our casting workshop on-site to a new larger premises also in Chichester. Our casting house not only casts our jewellery designs but also for others in the industry based around the UK.
Casting your design.
From CAD to Cast
Model-making. A 3D model is created on our 3d printers from a digital file created by our cad designers.
Spruing/building up. The wax models are added to the tree (a main feed/trunk with smaller branches/sprues joined to the models.
Investing. The ‘tree’ of models is then put in to a metal tube ‘flask’, they are then engulfed in a plaster of paris type material (Investment).
Burnout. When the investment is cured the flasks are put into a hot kiln. During this process the waxes are burnt out of the investment leaving a void.
Metal Casting. Once the flask is up to the appropriate temperature for the material being cast it is then transferred to the casting machine where the molten metal is poured into the flask.
The casting machines we use are: A tilt and pour machine, An over pressure machine, and a centrifugal machine.
For those of you who are really interested in this process and want to know more about the 3d printing and casting process, please ask for Tim or Chris who will try to answer your questions. Sometimes it might even be possible to arrange for you to visit the casting workshop for some extra info from the casting technicians if they are not too busy.
