Inspection Process
- Rawmaterial testing
- Finished products testing
- Pre-packaging inspection

Raw Material Testing
All our materials undergo testing and analysis using our professional equipment before production to meet international standards.

Hardness Testing
We use Rockwell hardness tester to inspect each batch of materials to ensure that the hardness meets the standard.

Density Detection
Using Metallurgical microscope to inspect metal molecular structure, steel density, oxide and other microstructure

Ingredient Testing
To ensure that the composition meet international standards, we use spectrometer to inspect the chemical element content of all materials.
Pre-packaging Inspection

Measure the dimensions

Check coating

Check appearance
Finished Products Testing
Use microscope to inspect the threads for burrs, gaps, or other defects. Each order, we will test the extreme performance on different workpieces.
