From the analysis of the heat treatment process, due to the residual heat quenching after forging, the FAG bearing steel balls are not spheroidized and annealed, so the grains are coarse and there is a band structure; at the same time, the carbon content in the quenched martensite is very high, and ... read more
The stainless steel ball is the most important part of the bearing and the rolling element most used in the bearing industry. Its quality directly affects the bearing quality. The subsequent processes of stainless steel ball production, namely, automatic cleaning of stainless steel balls, automatic ... read more
From the launch of raw materials to the completion of product processing, the steel ball requires multiple detection auxiliary production processes, which mainly include: cold pier → smooth ball → heat treatment → strengthening → hard grinding → preliminary research → sorting → refined research. 1. ... read more
The material of toy plastic balls needs environmental protection and safety, and must meet the standards of toy product certification.At present, there are not many plastic raw materials that meet these standards, especially in the domestic toy industry. Unsafe plastic toys in toy products are PVC p... read more
