Future gear trend plastic gear hegemony

[Abstract]:
The application range of gear molds can be roughly divided into three aspects: molds for plastic gears, molds for powder metallurgy gears, and molds for precision forged bevel gears.
The application range of gear molds can be roughly divided into three aspects: molds for plastic gears, molds for powder metallurgy gears, and molds for precision forged bevel gears. Among them, the demand for plastic gear molds is relatively large. Professor Shi Zhaoyao said: 'The main use of gears is two, 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 increasingly using plastic gears in the choice of power transmission. This is because plastic gears have many advantages, such as low transmission noise, vibration absorption, self-lubrication, etc., and plastic gears can be opened for mold production with high production efficiency. It should be said that plastic gears will be used more and more in the gear industry, which is a worldwide trend. '
Professor Shi said that the current low-end gear molds can be produced in China, and high-end gear molds rely on imports. There are not many factories specializing in gear molds in China. Most of them are gear molds made by the gear factory. The gear factory often has a working section or a workshop to undertake this work. In the precision forging bevel gears, the bevel gear molds manufactured by the company, such as the gear teeth, the Jiangsu spacecraft, and the Pacific precision forging, are better in the gear mold industry, and the quality of the precision forged bevel gears is also higher. In terms of plastic gears, plastic gears and their molds are mainly distributed in two areas. One is Ningbo, Zhejiang, there are more than 340 plastic gear factories, and it is also the largest plastic gear mold production base in China. The other is Shenzhen Baoan. It is mainly based on Hong Kong-funded enterprises, with high precision and is mainly used for export.
Looking at the status quo of China's gear molds, it can be described as mixed. The good news is that gear mold production has a certain foundation, and the development trend of plastic gears will bring more market space to gear molds. The worry is that the level of domestic production gear molds is still some distance from the world advanced level, and Under the trend of the gear industry, especially the plastic gear industry, the domestic response to market changes is not sensitive enough, and it is difficult for supporting research to keep up with market demand.
