Foundry Casting manufactures custom stainless steel investment cast impellers from approved customer drawings or physical samples. These parts are made to transfer energy to liquids or gases in rotating equipment. The product geometry, operating environment, mating interfaces, quantity, and verification requirements are reviewed before production.
Wax pattern, ceramic shell, gating, pouring, and solidification details are reviewed for the approved geometry. Particular attention is given to blade profile, hub bore, concentricity, balance, flow passages, surface condition, and corrosion environment. Material, dimensions, tolerances, heat-treatment condition, surface finish, and inspection requirements are confirmed for each order. Secondary work may include gate removal, heat treatment, cnc machining, polishing, passivation, and dynamic balancing as specified.
Inspection items, methods, and acceptance criteria are agreed before production. Packaging and the delivery schedule are confirmed after the product requirements, quantity, and shipping method have been reviewed.
