In relation to metalworking, casting is the process in which metal is liquefied and poured into a mold which is then cooled and solidified into the shape of the mold’s cavity. The solidified piece of metal also referred to as the casting or ingot is then released from the mold to complete the process.

In metalworking and jewellery making, casting is a process in which a liquid metal is somehow delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a 3-dimensional negative image) of the intended metal is poured into the mold through a hollow channel called a metal and mold are then cooled, and the metal part (the casting) is extracted.

This directory contains information about hundreds of metalcasters in North America. If you aren’t sure which metalcasting process you need to produce your component, our Casting Alloy & Process Selector (CAPS) is integrated into this directory system.
