They have a design and shape that allow a perfect closing during the centrifugation process. They are manufactured in zamak material and marketed in 3 kg containers.
There are three different types of centrers:
- Standard model, suitable for casting metals in silicone and rubber moulds. Allows easy opening of the mould after casting.
- Special resin model, designed to keep the mould perfectly closed when the pressure is removed from the centrifuge plates and the inner resin parts that have not yet reached their optimum polymerisation and cooling point are not deformed.
- Small dummy model specially designed to surround the piece, fasten or fix the mould around it and avoid displacements.
