The future of my country's gear mold demand has an infinitely bright future

Looking at the current situation of gear molds in my country, it can be described as mixed. The good news is that gear mold production has a certain foundation, and the general trend of plastic gear development will bring greater market space for gear molds; the worry is that the level of domestic production of gear molds is still far from the world's advanced level, and the With the development trend of the gear industry, especially the plastic gear industry, the domestic response to market changes is not sensitive enough, and supporting research is difficult to keep up with market demand.

There are two main uses of gears, one is to transmit motion, and the other is to transmit power. At present, domestic plastic gears are mainly used to transmit motion, and the United States is now adopting more and more plastic gears in the choice of transmitting power. This is because plastic gears have many advantages, such as low transmission noise, ability to absorb vibration, self-lubricating, etc., and plastic gears can be mold-opened and processed with high production efficiency.

Plastic gears will be more and more used in the gear industry, which is a worldwide trend. According to Luo Baihui, secretary general of the International Mould Association, the scope of application of domestic gear molds can be roughly divided into three areas: molds for plastic gears, molds for powder metallurgy gears, and molds for precision forging bevel gears. Among them, the demand for molds for plastic gears is relatively large.

At present, medium and low-end gear molds can be produced in China, and high-end gear molds mostly 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. In terms of precision forging bevel gears, the bevel gear molds manufactured by companies such as Zhuzhou Gear, Jiangsu Spacecraft, and Pacific Precision Forging are relatively good in the gear mold industry, and their precision forged bevel gears are of higher quality. In terms of plastic gears, in general, plastic gears and their molds are mainly distributed in two regions. One is Ningbo, Zhejiang, where there are more than 340 plastic gear factories, which is also my country’s largest plastic gear mold production base; the other is Shenzhen Baoan , Mainly Hong Kong-funded enterprises, with high product precision, which are mainly used for export.
