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.
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 balls with better wear resistance. It is the only domestic company that has formed a series of products. Used in the ink manufacturing industry.
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).
This standard is an important standard to ensure that the steel ball is not broken.
This standard is an important foundation to ensure that the steel ball has high wear resistance and high hardness.
