CASTING

The casting process involves heating the metal until it becomes liquid. It is then poured into moulds to achieve the required shape. After casting, the parts may then be machined and heat treated to achieve dimensional and strength characteristics.

Compared to forging, casting generally requires a lower up front tooling cost. Actual cost depends on the casting process – ie, sand casting, die casting, lost wax etc.

Westray supplies both cast iron and stainless steel castings for specific applications.
