Overmolding consists of molding a shape on a part of a different material.In this example, the foundry makes it possible to make the teeth of the pinion around the steel axis.
It is possible to overmold in zamak most materials with a melting temperature below 400° and even certain plastic materials.
Finally, it is possible to use zamak injection to connect 2 parts of different materials (e.g.: an axis on an aluminum bell or even on a magnet).
