Production Process

JHMT adopts a fully automatic production line, and the all the processes are tracked and controlled by computers. The production line adopts variable-frequency motors to truly control temperature and speed, real-time monitoring, and maximize the stability of product quality.

    JHMT has established a long strategic relationships with local material suppliers like Huaigang and Nangang, which ensure all balls supplied to our customers are made from the high quality raw material.


    The rolling equipment independently researched and designed by JHMT greatly shortens the time of replacing guide plate and reduces the surface defects of steel balls.


    The heat treatment processes independently researched and designed by JHMT ensure the balls obtain uniform and dense microstructure, so as to achieve high abrasion resistance and impact resistance.
