Relays were produced in 1992-1997. In 1997, the company transformed the production of solenoids and solenoid valves, and became a long-term supplier of well-known domestic and foreign companies such as Midea, Gree, Siemens and BYD.

Due to business development needs, the company was renamed and re-registered. The registered capital was RMB 10 million, and the plant area was expanded to 8,000㎡.
