AISI 304 Stainless Steel Exhaust Manifolds with CNC Machining

SEBON is specialized in AISI 304 stainless steel exhaust manifolds precision casting. We can produce automobile exhaust manifolds, car exhaust pipes, vehicles exhaust manifolds and tractor exhaust pipes. Auto exhaust system AISI 304 stainless steel castings with distinct edges and corners, size precision (critical dimension can reach ct5-ct6 level) and surface smoothness (casting surface roughness Ra 6). For castings can also be plastic, with the press machine, fixtures and measuring tool calibration castings.
