Made from Germany, with stable performance, long service life, smooth and flat surface, high dimensional accuracy, and good mechanical properties.

Introducing Japanese precision punching machines and Japanese precision molds, with high chain plate accuracy, and importing German pin shaft machines, with consistent precision in part sizes.

The surface of the pin shaft is infiltrated with Cr-V to enhance wear resistance。

Chain plate isothermal treatment to enhance fatigue performance.

The independently developed smooth punching technology is mainly applied to chain plate hole punching and peripheral punching, which can achieve a 90% bright band of holes and improve the chain durability life by more than 50%.

100% online automatic strengthening pre tensioning ensures that all products are strengthened, improving fatigue and wear resistance.
