Profile: Hebei Yogem Castings Co., Ltd is a supplier of OEM castings. The materials involved are grey iron/ductile iron, aluminum alloy, stainless steel, duplex/supper duplex, alloy steel, and heat-resistant steel. We produce them by lost wax (silica gel & water glass), pre-coated sand and resin sand. Our products are widely used in the field of pumps, valves, oil & gas, automotive, food machines, agriculture machine, and construction sectors. Unlike forging, casting uses liquid metal to make the valve. These metals are melted into molten liquid and poured into various molds. Annealed cast ductile iron resists fracture even when it is being bent, twisted or deformed.
