Quality System

Innovation and Development

The lightweight of vehicles is the development trend of vehicle manufacturing industry; automobile wheel is the key component of vehicle running. Our company had co-researched and made solid cooperative relations with Shougang Group. The current 22.5x8.25 specification 15°DC steel wheel made of 6mm-380CL wheel steel have been in batch use in the US market for more than 10 years, and never occurred any quality problems.

 

General rim with 6mm-380CL, using the existing continuous flash butt-welding equipment can ensure the welding quality and pass rate. Light weight rim are made of 5mm-590CL materials, as with existing continuous flash butt welding equipment, heat affected zone flaring, dilatation and thinning cracking are very easy to occur. After technology upgrades of research and development, and by using pulse flash butt welding machine, our company’s lightweight wheel cracking rate was reduced from 10%-23% to 1.0%.
