Product Process:
1.Raw Material
Each batch of raw material steel is inspected and classified according to different material (carbon, stainless, chrome), size and
quantity, which marked with the Material Cert. The qualified steel comes to the quarantine area; the unqualified will be rejected
with a record.
2. Wire Drawing
The steel is made into different sizes according to the needed requirements.
3. Heading
The raw material certified is worked on high-speed casting machines to cast into different size pieces.
4.Flashing
This step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of
casting and to increase the precision of the ball.
5. Heat Treatment
Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be
achieved with the materials used.
6.Lapping i (Grinding)
Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the
balls the next, final lapping process. 
7. Lapping ii
This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower
than that required under GB/308-2002
8. Selecting and Final Inspection
The sorting machines together with the manual detecting and modern testing processes, largely ensures the high quality of our 
products.
