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 AMS2750 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.
