New technology brings high efficiency and new ideas open up new fields.

As a kind of power transmission mechanism, helical gear has higher tensile strength requirements. The traditional gear milling method is inefficient, big energy consumption and unstable processing quality, which is difficult to meet the requirements.

  Sijin intelligent has developed a new rotary cold heading process, which realizes the cold heading of helical gear and has been successfully applied. This technology effectively improves the hardness of the tooth surface, increases the strength and toughness of the tooth core, improves the mechanical properties of the gear, as well as its production efficiency, and extends the service life of the gear. At present, this cold heading process has successfully applied for national patent.
