Southwest Castings builds automotive investment casting parts for vehicle transmission, exhaust, intake and suspension systems. Material options include stainless steel, carbon steel and heat-treated alloy steel, processed through investment casting, heat treatment, CNC machining and surface finishing.
Before tooling begins, our manufacturing team in China checks each customer drawing. This review examines wall thickness, reference datums, machining allowances, specified tolerances and access for inspection.
The approved specification determines the repeat-order route, including tooling, casting, heat treatment, CNC machining, drilling, grinding, polishing and final dimensional inspection.
Southwest Castings supports OEM purchasing with manufacturing and export services from China. Submit your 2D application drawings, 3D models or samples; material certification and dimensional inspection reports are available by arrangement.
For an itemized production quotation, email your drawing, alloy grade, yearly volume, required finish and shipping destination to export4@tousinmetal.com.
