From chill gravity casting to sandblasting: the Production Process

The castings are obtained by inserting a sand core inside the casting mould, called chill. Through feeding furnaces pre-melted brass is poured into the moulds fitted on the casting machines, built internally in our Company.
Easier said than done. The right mixing formula of sand, the correct melting times and speeds, the structure of the casting gates as well as the casting system itself are the basis of a highly manual process. This is also influenced, even if only partially today, by the experience level of the operators, trained on field and who store techniques that blend ancient manual skills with modern technologies.

The production process then includes other steps in the finishing, seal pressure test and in final sandblasting departments to ensure a good level of surface quality.

Some castings are supplied raw to respective customers, whereas if requested, mechanical machining is also carried out in our department equipped with Transfers and Machining Centres, as well as testing and control tools of the latest concept.
