Coating process(cathode electrophoresis coating line): Using advanced anode electrophoresis coating equipment from pretreat, electrophoresis to dry procedure with convey band to insure good resistant rust for steel wheel surface for 5-7 years.salt water spraying test last for 720h.
Formality process (1500T oil-pressure machine) To assure good plane for spoke panel and good spoke height by 1500T oil-pressure machine.		Combination process (320T oil-pressure machine): Over match between spoke and rim by 320T oil-pressure to assure separateness precision and welding strength.100% runout inspection to improve safety for travel.
Butt welding process(750KVA flashing butt welder): To assure rim to be penetrated welding and avoid to weld cracking and rim explode.
