Before the epidemic, magnetic toroidal inductors were produced in the traditional way, that is, by manual winding. Due to individual differences among workers, there were differences in working methods and production habits, and the quality of the products produced was inconsistent, which affected the customer's experience. Therefore, during the epidemic, we communicated and cooperated with machine equipment manufacturers to jointly develop fully automatic winding machines with various styles to meet the production needs of various winding methods. After a few years of running-in, the current machine equipment winding production technology is very mature and can carry out 24-hour uninterrupted production operations, which greatly improves production efficiency. The quality of each product is also guaranteed, completely replacing the traditional manual operation method, and meeting customer requirements in terms of production capacity and quality.
