Hangzhou Zehe Precision Machinery Co., Ltd. is located in Fuyang District, Hangzhou City, Zhejiang Province, beside the beautiful Fuchun River. The company focuses on the R&D, production, and one-stop delivery of low-temperature wax silica sol investment casting. As a domestic precision casting manufacturer deeply engaged in this process, it provides high-cost-performance solutions for complex precision castings to the equipment manufacturing industry, with core advantages including controllable costs, stable precision, reliable forming, and efficient delivery.

The company adopts a low-temperature wax pattern making and silica sol shell investment casting process. The wax patterns are stable, not prone to shrinkage depression, and offer high process flexibility. The silica sol shell provides good high-temperature strength, excellent permeability, and a clean surface, balancing quality and cost. Casting dimensional accuracy can reach CT5–CT8 grades, with surface roughness Ra 2.5–6.3 μm. This process reliably produces thin-walled parts, complex internal cavities, multi-curved surfaces, and near-net-shape or net-shape castings. It is compatible with a wide range of materials, including carbon steel, stainless steel, alloy steel, heat-resistant steel, high-chromium cast iron, and ductile iron...
