Shanghai Qingshenglai Rearview Mirror Co., Ltd. (QSL), a leading OEM manufacturer of automotive and motorcycle components based in Shanghai’s Jinshan Industrial Zone, has officially commissioned a new fully automated tube bending and welding production line. The upgrade marks a significant milestone in the company’s ongoing capacity expansion and process optimization strategy, increasing its precision tubing output by 40%.

The new production line integrates advanced CNC tube bending equipment with automated welding stations, enabling QSL to produce high-precision tubular components with greater consistency, faster cycle times, and reduced material waste. The system is designed to handle a wide range of tube specifications for applications including rearview mirror rods, gearshift levers, and various structural components for the automotive, agricultural, and construction machinery sectors.

“This investment reflects our commitment to meeting growing customer demand while maintaining the highest quality standards,” said a QSL spokesperson. “The automated line not only boosts our capacity but also enhances our ability to deliver complex tube geometries with tight tolerances—critical for our partners in the commercial vehicle and heavy equipment industries.”

QSL has long been recognized for its comprehensive in-house manufacturing capabilities, which span injection molding, stamping, tube shrinking, bending, welding, painting, and automated assembly. The company serves a distinguished roster of clients including Ganxiang Rearview Mirror, Lvxiang Rearview Mirror, Deren, Magna, Sumitomo, Yawata, Kubota, and John Deere, producing components for automotive, agricultural, and construction equipment applications.

The new tube bending and welding line is expected to support QSL’s growing OEM business, particularly in the area of metal components such as gearshift levers, mirror rods, and custom tubular assemblies. With the additional capacity, the company is well-positioned to take on larger-volume orders and more complex projects from both domestic and international customers.

QSL operates under a complete and scientific quality management system and holds ISO 9001 certification. The company’s integrity, manufacturing strength, and product quality have earned widespread recognition across the industry.
