Quality Control

Our zero-defect quality framework integrates continuous electronic inspection and mechanical testing:

High-Speed Optical Sorting:

100% automated vision inspection removes defective screws (e.g., blunt tips, off-center heads, damaged threads).

Drilling Speed & Capacity Audit:

Automated testing measures the time and downward force needed to penetrate standard test sheets.

Torque-to-Failure Analysis:

Destructive rotation testing determines maximum torque strength and strip resistance.

Coating Thickness & Salt Spray Test:

Microscopic check of coating thickness plus continuous salt spray testing.

Flexible Packaging & Global Logistics
