As a premier custom metal casting manufacturer and full-service metal casting foundry in China, Zhangzhou Hengchang Machinery specializes in delivering high-quality, precision-engineered custom cast metal parts in grey iron, ductile iron, cast steel, stainless steel, aluminum and bronze. From a single prototype to mass production of over 5,000 pieces, our industrial casting solutions are built to meet the rigorous demands of global B2B buyers.
Unlike a single-process supplier, we run four complementary moulding lines — resin sand casting, green sand casting, shell moulding casting and vacuum casting — plus in-house CNC machining, so your custom cast metal parts move from raw casting to ready-to-assemble component under one roof.

Grey iron, ductile iron, cast steel, stainless steel, aluminum and bronze — six material families on four moulding lines, so we recommend the process that fits your part, not the one we happen to run.
In-house CNC machining, heat treatment and shot blasting eliminate third-party handoffs — shorter lead time, single point of quality accountability.
From one-off sample approval to stable mass production, with pattern tooling retained for repeat orders. Typical quotation response within 24 hours.
Mill test certificates, dimensional reports and PPAP-style documentation on request. See why buyers choose us →
Send us your 3D model (STEP / IGS) or 2D drawing with material grade, weight and annual quantity. As an experienced industrial casting manufacturer, our engineering team will review manufacturability and return a quotation with recommended process, tolerance and lead time within 24 hours.
