Gravity Die Casting

Our capability in this very long established casting method has been honed over the last 30 plus years. We comprehensively engineer our tooling for long life to produce high quality Aluminium Castings in a variety of alloys to suit their final use. Cast weights range from a few grams to 25 kilograms or more.

This method produces very accurate castings with a good surface finish when larger volumes are required with a lower unit price. The close tolerances, which can be achieved makes Gravity Die Castings very suitable for machining using CNC equipment.

Complex internally cored castings are achieved using shell handmade or blown sand cores. These are produced from semi automatic machines incorporating wood or cast iron shell core boxes which give accuracy, intricate detailing and fine core surface. Cores are produced in a variety of sand medias to suit the parts requirements.
