China Plastic Balls Manufacturer Introduces The Production Knowledge Of Steel Balls

China Plastic Balls Manufacturer shared that from the launch of raw materials to the completion of product processing, multiple testing auxiliary production processes are required, which mainly include: cold pier → smooth ball → heat treatment → strengthening → hard grinding → preliminary research → sorting → lapping.

1. Raw material quality standards

The material used for the ink special steel ball is GCr15 bearing steel. On this basis, Qingdao Feite has innovatively produced GCr15SiMn and martensitic stainless steel steel balls with better wear resistance. It is the only domestic company that has formed a series of products. Used in the ink manufacturing industry.

2. Steel ball dimensional accuracy and geometric accuracy standards

For steel balls with a diameter of 1.2～12.7mm, the variation of the ball diameter is ≤25μm; the variation of the batch diameter is ≤50μm; the spherical error is ≤25μm; the gauge value is ±150μm (can be formulated according to user requirements).

3. Steel ball crushing load standard

This standard is an important standard to ensure that the steel ball is not broken.

4. Quality standard of steel ball heat treatment

This standard is an important foundation to ensure that the steel ball has high wear resistance and high hardness.
