With the gradual automation and intelligence of automobiles, Hualian is optimistic about the market development of automobile electric tools, so it has independently developed two series of electric gearboxes, which are mainly suitable for automobile wipers.

This product is made of sintered hardened materials. Thanks to the profound experience in the manufacture of adjusting arm accessories, the performance, dimensional accuracy and gear accuracy of the gearbox are higher than ordinary products on the market.

The process flow is similar to that of the adjustment arm production line. It is divided into 7 manufacturing processes and 5 dimensional performance inspection processes. Some planet carriers use needle-roller press assembly technology.
