It is the only company in China that goes to the counter to wholesale and retail motor mold products to motor industry manufacturers across the country. For customers, it has achieved a "zero" cycle for standard motor mold production and is deeply favored by customers.
The principle of the company's development of new products is: develop one, standardize one, and transform one, so that new products can quickly become large-scale production products. The complex and precision molds developed, such as large precision fan-shaped molds for motor punching, large block precision molds for motor punching, and multi-station progressive molds for iron cores, have successfully achieved commercialization transformation and quickly formed large-scale production products.
