Quality Assurance

Before packing, steel balls are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.

Product Process

 

Above pictures are showing our 14 steps production process.

And we have below advantages:

1. We do Metallographic analysis on every batch of material and record the test results

2. What we use is high speed heading machine, which has higher work efficiency than tradition machine

3. We apply different heat treatment methods to different materials, for example, nitrogen protection furnace for 420C stainless steel ball.

4. We have one more process which other factory may not use, we improve the compressive stress and surface hardness of the steel ball by a stengthening machine

5. Roller sorting avoid of size mixing

6. Pack according to customers' requirements

7. Each machine has an operation record and an inspection record, and these records are saved for ten years

8. We have a process card for each batch of steel balls, and different color of card for different material to avoid of any mixing mistake

9. We have a laboratory to do final inspection for every batch of steel balls, checking on size, surface, roundness, hardness and etc.
