Made for automotive cooling assemblies, this custom cast water pump housing incorporates volute passages and machined connection ports. Tousin Castings coordinates investment casting and export from China, following approved drawings and a clearly agreed production quotation.
Automotive Water Pump Housing Casting is a precision cast component for automotive cooling assemblies. Tousin Castings produces these custom pump housings in China, reviewing customer drawings to define the casting and machining requirements before preparing a direct factory quotation.
Available alloys include stainless steel, carbon steel and heat-resistant alloy steel. Typical casting weights range from 0.1–50 kg, with ISO 8062 CT5–CT6 tolerances where achievable. Customer drawings control the passages, mounting holes and finish-machined sealing interfaces.
Silica-sol investment casting forms the water passages before heat treatment, CNC milling, drilling, tapping and surface finishing. Bearing locations, gasket faces and connection surfaces receive finish machining to establish the dimensions required for reliable assembly.
Orders may include dimensional records, material reports and specified pressure or leakage tests. A typical minimum order is 100 pieces, with production taking about 35–40 days after sample approval. Email the housing drawing to inquiry@tousinmetal.com for review.
