SINCE 1985

About Us

Jonstar was born in 1985. With the mission of jointing the world and driving the future, the company has been committed to providing high-precision and high-efficiency reducers together with overall transmission solutions for the industrial transmission field. And through continuous technological innovation and reforms to promote the overall development of the transmission industry and save resources for the society.


After years of development, we already have 223 staff members, including 32 professional technical R&D members. Besides, Jonstar also developed a series of reducers, such as the precision planetary gear reducer, the precision dual lead worm gear reducer, the helical-hypoid gear reducer. Those reducer products are popular in the food, environment protection, medical, mining, petroleum machinery, and solar energy industries.


Jonstar will adhere to the focus strategy called precision reducer with its foresight. And, we will build a complete global sales channel and service network to provide the best reducer products and transmission solutions for users in the transmission industry.

The Origin of Jonstar

    We are the witnesses, pioneers, and practitioners of the reform and opening-up.

    We want to achieve our value and be successful in this choppy market.

    In 1985, the reform and opening-up slowly took place. There were opportunities and dangers, and the three aspiring young men decided to quit as the employees of the state-owned business. With the scarce funds, they started the research and development of the Planetary Cone & Disk Step-Less Transmission Speed Variator and no one knows if they would succeed.

  • JONSTAR Early start
It is not smooth at first
The development of the Planetary Cone & Disk Step-Less Transmission Speed Variator


The research and development of the Planetary Cone & Disk Step-Less Transmission Speed Variator were not smooth because it was in the early stage of the reform and opening-up, and the society was relatively closed. Without the theoretical basis of reducer, high-quality materials, and the complete equipment, it was hard to develop the product.

First generation product

Planetary disc stepless transmission


The development of the planetary disc continuously variable transmission has not been smooth sailing. In the early stage of reform and opening up, the society was still relatively closed and the information was relatively blocked. Is troubled by a series of problems such as imperfections

Inheritance and development
Stable development of the enterprise and second-generation inheritance

After 15 years of development, the company has begun to take shape and has the ability to develop a full range of reducers.

As entering the new century, to inject the young blood and the power of youth into the enterprise, the second generation took over the company’s further development, and the first generation all withdrew from the management decision-making level.


The Continuous and Rapid development makes the turnover exceed the 100 million Yuan mark

Inheritance and development

The company continues to develop rapidly

After 15 years of meticulous management and development by the first-generation business entities, the company has accumulated a solid technical foundation, and the company has begun to take shape, laying a solid foundation for further upward development.

The second-generation business entity took over the company's management and management, and started the transformation of the company from a traditional workshop company to a modern management company.

Municipal Enterprise Technology Center

National high-tech enterprise

Jonstar R&D center is a municipal enterprise technology center that has been in 35 years. Adhering to the spirit of inheriting ingenuity and facing the future together with the mission of jointing the world and driving the future, Jonstar has carefully studied the latest development trends of the global transmission industry and developed a series of high-quality reducers for customers. And in the field of reducer research and development, we have 32 professional engineer teams, and they can provide customized service for global users of our products. We also have more than a 1000-square-meter test site with the world's top equipment for research and development, and all R&D programs have been rigorously and reliably verified. At the same time, 3% of Jonstar's annual turnover is a special R&D fund to explore the most advanced transmission technology.
