Dongying Giayoung Precision MetalCo., Ltd
About
Dongying Giayoung Precision Metal Co., Ltd specializes in silica sol investment casting at Dongying in Shandong, China, pouring stainless, heat-resistant, carbon, and low-alloy steels along with high-temperature and non-ferrous alloys. Thirty years of foundry practice, a technical staff above 100, three casting lines, and two machine shops let the firm work more than 1,000 alloys and turn out over 1,300,000 precision parts each month, with 1,000-plus different parts in production simultaneously. Capabilities run from casting through heat treatment, CNC machining, surface finishing, and assembly, supplemented by 3D printing, process simulation, and soluble or ceramic core methods for complex internal passages. Holding ISO 9001, ISO/TS 16949, and CE/PED certificates plus approvals from nine marine classification societies and 44 patents, Giayoung supplies precision castings and tank valves to pump and valve makers rather than finished pumps.
