Quick and simple to execute, it is possible to create
faithful series reproductions, even from a just one model.
What is Spin Casting
Centrifugal Rubber Mould Casting, or just simply Spin Casting, is a method of utilising centrifugal force to produce metal castings from a rubber mould. By using this process, it is very easy to produce many copies of a particular object from a single model.
The freedom to choose: systems
A broad range of technological options stands side-by-side with traditional systems (where metal is manually poured into moulds), functional production lines with automated metal casting, that, notably reducing work cycle downtimes, make it possible to boost hourly outputs.
Phases of the spin casting manufacturing process
Mould vulcanization
- The models to be reproduced are placed between two “raw” rubber discs inside a special mould box.
- The box is then introduced in a press called a vulcanizer where the rubber is pressed and heated for about an hour.
- At the end of the process, the shape of the model remains impressed permanently on the discs, which constitute the mould.
Carving channels, finishing the mould
- The vulcanized mould should be extracted from the moulding box.
- The silicone rubber discs are separated. The moulds are removed.
- Scalpels are used to create input channels. Thanks to these channels, the melted metal reaches each of the impressions left by the models.
Casting metal in rubber
- Moulds made with this method can be positioned within the spin-caster.
- Melted metal is taken from the smelter and poured in the conduit that leads to the spin-caster. The way the metal is poured changes according to type of system, manual or automatic.
- The first castings are necessary to improve and correct the channels if the moulds don’t fill up completely.
