Stainless Steel Pump Body Investment Casting serves industrial pumps requiring corrosion resistance and controlled dimensions. Honyang Metal manufactures these custom bodies in China, bringing investment casting and CNC machining together under an approved drawing, inspection plan and direct project quotation.

Select from stainless steel grades, carbon steel and alloy steel. Typical cast components weigh 0.1–50 kg, with ISO 8062 CT5–CT6 tolerances. Approved engineering files establish internal passages, wall sections, flange connections and the machining stock needed for finishing.

Heat treatment, CNC machining, drilling, tapping, polishing and passivation follow silica-sol lost-wax casting as specified. Bores, flange surfaces and threaded ports receive finish machining to achieve the dimensional fit needed for sealing and pump assembly.

Documentation may cover material certification, dimensional inspection and optional pressure or leakage tests. Typical orders start at 100 pieces and require about 35–40 days after sample approval. Request a project quotation by sending the drawing to export@tousinmetal.com.
