Key Manufacturing Capabilities

QSL operates a comprehensive in-house production system for tube processing, featuring:

• Tube Shrinking – Precision end forming and diameter reduction for seamless tube-to-component integration

• Tube Bending – CNC-controlled bending for complex geometries, multi-plane bends, and tight-radius applications-

• Metal Welding – Automated and manual welding for structural assemblies, including MIG and spot welding-

• Sheet Metal Fabrication – Stamping, forming, and welding of brackets, mounts, and structural supports

• Surface Finishing – Painting, powder coating, and anti-corrosion treatments to meet industry standards

Our newly launched fully automated tube bending and welding line has increased precision tubing capacity by 40%, enabling us to handle high-volume orders with repeatable accuracy

Applications
