Company Profile

DeMei Precision Transmission Co., Ltd.

Established in November 2021, DeMei Precision Transmission is a high-tech enterprise specialising in the research, development, manufacture and sale of harmonic reducers, articulated modules and actuators. The company’s predecessor had been deeply involved in the field of harmonic drive for over a decade, accumulating a wealth of technical expertise and overcoming key technical challenges such as the development of specialised materials for reducer characteristics, tooth profile design and manufacturing processes. To date, the company has obtained more than 40 national patents and over 10 software copyrights, with all product performance indicators meeting national (A) grade standards. Adhering to a philosophy of quality first, DeMei Precision regards technical prowess as the core driving force behind its development. The company has developed over 190 specifications and models of harmonic reducers, launching micro harmonic reducers, the D-Mroint series of articulated modules and IP67-rated actuators, and has fully realised standardised and mass production. From raw material procurement and precision machining to final assembly, stringent quality control is implemented throughout the entire process to ensure consistency in product accuracy and long-term stability upon delivery. Our products boast outstanding characteristics such as high precision, high rigidity and a long service life (up to 20,000 hours), and are widely used in high-precision and cutting-edge fields such as industrial robots, collaborative robots, humanoid robots, semiconductor equipment, CNC machine tools and aerospace. The company currently operates two major production bases in Shenzhen and Zibo. It has successively invested nearly 100 million yuan in state-of-the-art, fully automated high-precision gear machining production lines, establishing an end-to-end independent production system covering everything from raw material processing to finished product assembly. The company is committed to providing global customers with precision transmission solutions that deliver outstanding performance and reliable delivery.
