We ensure strict quality control through the following five key measures:

1. Dimensional Control

Dimensional control is the foundation of quality.

-Gauges shall be manufactured in accordance with customer drawings and used for parts inspection.

-All finished products shall be subject to acceptance inspection in accordance with the customer's CTQ (Critical to Quality) specifications.

2. Process Inspection

Our in-process checks monitor production at every stage — from raw material to finished part — to catch deviations early and maintain consistent quality throughout.

Appearance – workmanship(Level 1)

-Surface (no scratch, damage, dents, dirts, sharp edges, gaps, deformation, etc.)

-Color (material, paint, plating,enamel,electrolysis)

-Cleanliness of surface

-Mechanical damages (no big scratch/es, bumps, hits, etc..)

-Manufacturing failures (no rust deformation, rust screws, sharp edges, bad welding)

3. Salt Spray Test

To verify corrosion resistance, we perform salt spray tests on coated and plated surfaces, ensuring our products can withstand harsh environments and prevent rust.

4. Drop Test

We conduct drop tests to evaluate structural integrity and packaging effectiveness, ensuring our products survive transportation and handling without damage.

5. Packaging Acceptance Inspection

Our final packaging is inspected against customer requirements for protection, labeling, and cleanliness — ensuring that what arrives on site is ready to use, safe, and complete.
