Quality you can audit

Welding is a special process — you cannot see a bad weld from the outside. So we measure it.

Our quality department issues weld penetration reports with sectioned and etched samples, part number by part number, and they are available on request for the parts we quote you.

The management system is certified to IATF 16949:2016, scope manufacture of seat frame assemblies, design excluded. Certificates are issued in Chinese and English originals and are sent with our quotation.

Assemblies with threaded or bolted interfaces are additionally checked on a torque test rig.

The equipment behind those reports

Welding. 7 welding robots on the arc and spot welding lines, plus 20 TIG welding sets, 2 projection welders and 4 spot welders. The robots run the repeat-volume assemblies; the manual sets cover samples, low-volume variants and rework under the same weld specification.

Measurement and destructive test. A tensile tester, a torque and fatigue test rig, and weld penetration analysis equipment for sectioning and etching samples. Weld penetration is measured, not eyeballed — which is the only reason we are willing to put the reports in front of you.

Forming. High-speed CNC wire benders covering φ2–φ14 mm wire, with combined bend / flatten / pierce machines and upsetting heads; fully automatic laser tube cutting, multi-station CNC tube bending, necking presses and hydraulic presses covering φ8–φ52 mm tube.

PPAP, stated plainly

We compile and submit PPAP to the customer's requirement. We have not yet made a PPAP submission directly to an overseas customer — the parts we have built have reached Mexico, Thailand and Malaysia, but not on a PPAP package we submitted ourselves. Tell us your PPAP level and submission date together with the drawing and we will tell you straight whether we can hold it, rather than the two of us finding out in week three of a launch.
