Sanjack Casting supplies precision-cast pump and valve components for industrial fluid-control, automotive and general machinery operations. These parts are produced from stainless steel, carbon steel or selected alloy steel using silica-sol investment casting, followed by CNC machining where accurate bores, threads, ports and flange faces are required.
As China investment casting manufacturer and factory, we review each custom drawing before tooling. engineering check covers wall thickness, draft, machining allowance, datum selection, tolerance and inspection access. This reduces avoidable corrections during sample production and supports stable batch quality.
Our production route can include wax tooling, shell building, melting and pouring, heat-treatment, shot blasting, machining, polishing and dimensional inspection. Typical component weight is 0.1–50 kg, with casting tolerance commonly planned to ISO 8062 CT5–CT6 according to part geometry and process requirements.
Sanjack Casting works as Chinese manufacturer, exporter and supplier for custom pump housings, valve bodies, threaded covers and flanged components. Partners can create 2D drawings, 3D models or physical samples. Material certificates, inspection reports and sample approval can be arranged according to project scope.
For clear factory price, send product drawing, alloy grade, annual quantity, surface requirement and delivery destination. we’ll review manufacturability, tooling, sample schedule and production lead-time before quotation.
