Hand moulding

Hand moulding is a technique to make a sand mould from a pattern. Usually chemically bound sand is used. In this process, sand, mixed with resins, is poured loose onto the model.  After that it is compressed. Through the action of a catalyst, the resins ensure that the sand cures. Sand cores are used to form internal cavities and not loosening parts.

This technique is mainly used for very small series and/or large to very large pieces. In case of serial production, this technique can be automated to a certain extent.
