The
sand coated iron mould casting is a semi-precision casting method,
different from sand casting, lost foam casting(expendable pattern
casting), shell mold casting, investment casting. The casting method
adopts metal pattern( sometimes called sand coated metal pattern
casting) and cast iron cavity with shape close to the castings as the sand box iron
pattern. The near-shaped iron type is covered with a layer of 6~10mm coated sand to form into a casting mold for pouring into castings - this is what we said sand coated iron mold casting line.
Production process: Molding-Sand box closing-Sand box locked and pouring cup laid-Pouring-Castings-Shot blasting-Molding
At present, the production line can produce: wheels, brake drums, wear balls, crankshafts, high-speed rail parts, flywheel shells, water pump housing, canshaft, all kinds of gears, bucket teeth, elevator traction wheels, machine bases and casings, End caps, ductile iron pipe fittings, camshaft, valve body, etc.
