About Jinqiu

Our R&D and production are guided by Japan's mature technological systems

Our R&D and production adopt Japan's mature technological systems. We specialize in crystal oscillator housings, cast film machine manufacturing and R&D, and oil well pump plungers with surface treatment. Our plungers have been exported to Indonesia and the U.S. Our cast film machines are built on proven Japanese technology. Our 49U/S crystal housings have evolved from Gen 1 to Gen 6, and we are developing higher-end SMD alternatives while collaborating with Shanghai Jiao Tong University on new energy projects.
