sand castings and moldings

Sand casting is a less expensive moulding process than other systems. In addition, this form of production allows the casting of complex shapes, weighing from a fraction of a kilo to several tonnes. The surface finish of Airset and Greensand castings often shows evidence of sand grain however, this can simply and effectively be removed by secondary processing.

The "sand" casting represents a standard foundry machining. It is called in this way due to the fact that the melted metal is cast into a mould composed by a special sand, called moulding sand, which at the process end will be broken to permit the piece extraction. The first phase consists in the creation of a pattern made of various materials, around which the mould will be implemented
