manufacturing processes

Gravity Die Foundry

Our production facilities include semi-automatic hydraulic casting machines as well as conventional mechanically operated dies. These enable us to produce castings weighing from a few grams to 25 Kg and in batch sizes from 100 to 10000.

Sand Foundry

The boxless moulding method is used to produce castings weighing from a few grams to 50Kg. Our flow line has been designed to allow flexibility of production by minimizing setup time. Consequently production runs of any length can be accommodated easily.

Fettling/Finishing

A well equipped fettling shop ensures runners, risers and excess material are removed efficiently and to required standards. Glass bead and stainless steel shot blasting facilities remove adhering sand and improve surface finish where necessary.

Heat Treatment

Electric and gas heat treatment ovens on-site help enable Quality Castings to offer competitive lead times for heat treated castings. We have ovens calibrated to BSM54 allowing us to heat treat aluminium alloys to aerospace specifications.

Setting and Straightening

Certain designs of casting are prone to twist and distort during manufacture, particularly on removal from the die or during heat treatment. Quality Castings are equipped to check for this condition and set and straighten, to jigs where appropriate, hence maintaining dimensional accuracy.
