With the development of patented products (limit relays, stroke controllers, etc.), the company gradually evolved from the laboratory of the institute to the experimental plant, and then developed into an independent Ningbo Jiangbei Dunhoutang Power Plant, to today's Ningbo City. Jiangbei Dunhoutang Electromechanical Co., Ltd.
Dunhoutang® is a registered trademark of low-voltage electronic and electrical products produced by our company. At present, the main products include stroke controllers, magnetic switches, counters, rams, and time relays for injection molding machines. Established a supply and demand relationship with more than 40 injection molding machine production units. In the future, we will continue to make efforts to support the injection molding machine and make due contributions.
