Factory & Quality Control

Two production bases and one quality system. Shenzhen handles engineering, moulding and precision harnesses. Our Wuzhou, Guangxi plant (since 2022, over 10,000 m²) runs cable extrusion, moulding and full assembly lines. Together they produce 8 million+ cords a year.

Cable extrusion

Wuzhou has its own extrusion lines, which draw copper conductors and PVC compound through a die into insulated cable of the required diameter and shape. Making our own cable means we control conductor size, insulation thickness and consistency from the start.

Production process

Production floor

Laboratory & test equipment

The laboratory has been expanded since early 2023. It includes FLUKE electrical safety testers, a power cord comprehensive tester, an impedance tester, an automatic vibration tester, a 2D image measuring instrument, a natural-convection ageing oven and plug temperature-rise test equipment.

Quality control

• Incoming inspection (IQC): materials are inspected before they enter the warehouse; failures go back to the supplier.
• Sealed samples: every product has an approved reference sample that production is checked against.
• First-article and in-process inspection (IPQC): crimp pull-force is re-tested whenever the material, die, operator or batch changes, and every crimp is inspected.
• 100% testing: continuity (loop) test and visual inspection on every piece.
• Outgoing inspection (OQC): final sampling before shipment, with records kept for traceability.
• Daily improvement: defects found each day are analysed and fed back to operators the same day, with regular training.

The result is a defect rate below 0.02%. The quality system is certified to ISO 9001.
