The scope of application of the domestic gear mold can be broadly divided into three areas: plastic gear molds, powder metallurgy gear molds and precision forging of bevel gear with mold. Among them, the demand for plastic gear mold.
The main usefulness of the gear has two, a transfer motion, the other is the transmission of power. Domestic plastic gears are used to transmit motion, while the U.S. is now on the choice of the transmission of power, more and more plastic gear. This is because the plastic gears have many advantages, such as transmission and low noise, able to absorb vibration, self-lubricating plastic gear mold processing, high production efficiency. It should be said that the plastic gears in the gear industry will be more and more, this is a worldwide trend. ‘Middle and low gear mold in the country capable of producing high-end gear mold to rely on imports. The specialized gear mold factory is small, mostly by the gear factory to do the gear mold, gear factory are often set up a Section or a workshop to undertake this work. In the precision forging of bevel gear, bevel gear mold strains teeth, Jiangsu spacecraft, Pacific Precision Forging Manufacturing in the gear mold industry is relatively good, the quality of its precision forging of bevel gears are also higher. In plastic gears, in general, the plastic gear and mold are mainly distributed in two regions, one in Ningbo, Zhejiang, there are more than 340 plastic gear factory, China’s largest plastic gears mold base; the other is Shenzhen Baoan Hong Kong enterprises in the main, high precision products, mainly used for export.
Looking at the gear molds status quo in China can be described as mixed. The joy is that the gear mold has a certain basis, and the plastic gear development trend of gear mold to bring greater market space; the worry is that the level of domestic production gear mold with advanced world level there is still a distance, but also in gear industries, especially the plastic gear industry development trend, the domestic reaction to market changes is not sharp, and supporting studies are difficult to keep up with market demand.
