Industries served:

· Fluid handling: pump bodies, valves, pipe fittings (HT200/HT250, QT400-15/QT500-7)

· Construction machinery: gearbox housings, bases, hydraulic manifolds (QT600-3/QT700-2)

· Automotive & commercial vehicles: brake discs, hubs, differential cases, exhaust manifolds (CGI RuT300/RuT350)

· Rail transit: bogie components, brake shoes (QT450-10)

· Agricultural machinery: plowshares, gearbox shells (malleable iron KT330-08)

· Municipal & building: manhole covers, drainage grates (gray iron HT150)

· Energy & power: wind turbine nacelle frames, gas turbine casings (low-temperature ductile iron QT400-18AL)


Available casting processes:

· Green sand: high-volume medium-small parts like manhole covers, brake discs, pipe fittings

· Resin sand: medium-large parts, single or small batch, e.g. gearboxes, pumps, valves

· Shell mold: precision thin-wall parts such as steering knuckles, camshafts

· Lost foam: complex internal cavity parts like engine blocks, exhaust manifolds

· V-process: large flat castings like machine tool beds, bases

· 3D printing: rapid prototypes, complex conformal cooling channels, low-volume special shapes

Minimum order quantity: 1 piece. We accept customer drawings (2D/3D) or functional specifications for custom design. All castings come with material certificates, dimensional reports, and NDT options (UT/MT/RT). Surface treatments: anti-rust paint, hot-dip galvanizing, epoxy coating.
