Gear refers to a mechanical element with gears on the rim that continuously meshes to transmit movement and power. The application of gears in transmission appeared very early. At the end of the 19th century, the principle of the generative gear cutting method and the special machine tools and tools that used this principle to cut gear appeared one after another. With the development of production, the smoothness of gear operation was paid attention to.

Most of the middle and low-end gear molds can be produced in China, and most of the gear molds rely on imports. There are not many domestic factories that specialize in gear moulds. Most gear factories make gear moulds themselves. Gear factories often set up a section or a workshop to undertake this work. This makes the development of the domestic gear mold industry even more difficult. Related experts said that in order to promote a better and faster development of my country's gear mold industry, fundamentally solve the problem of dependence, and strive to improve professional technology in order to better serve the domestic gear mold industry.

As competition in the gear industry continues to intensify, mergers and acquisitions and capital operations among large gear companies have become more frequent. Domestic gear manufacturers are paying more and more attention to the research of the industry market, especially the in-depth research on the development environment of the company and the changes in customer demand trends. .
