Analysis of the current situation of powder metallurgy gear market

Nov 05, 2022

With China's accession to the WTO, the above shortcomings and weaknesses will be improved. This is because after China's accession to the WTO, the market will gradually internationalize, and the powder metallurgy market will get further expansion opportunities. At the same time, with the entry of foreign capital and technology, powder metallurgy and related technology will also be improved and developed. The current situation of powder metallurgy gear market is analyzed. The application scope of gear die roughly includes plastic gear die, powder metallurgy gear die and precision forging bevel gear die. Among them, the demand for powder metallurgy gear dies is the largest. At present, the development of gear dies in China is still in the primary stage, and most of the powder metallurgy gears with small and medium modules are processed with dies. Due to the deformation and shrinkage during the processing of powder metallurgy gears, and the accuracy change law after shrinkage, domestic research is not in-depth at present, which has become one of the main reasons restricting the development of powder metallurgy gear dies.

Although it is difficult to count P/M gears separately in the whole P/M parts, the proportion of P/M gears in automobiles and motorcycles is far greater than that of P/M parts in other fields, whether by weight or by the number of parts. Therefore, from the increase of the proportion of automobiles and motorcycles in the whole powder metallurgy parts, it can be seen that the powder metallurgy gears are in the position of rapid development in the whole powder metallurgy parts. The in-depth research report on the market supply and demand forecast of China's powder metallurgy gear industry from 2016 to 2021 shows that gear looks inconspicuous, but it is an important part of industrial equipment. The gear industry in China is basically composed of three parts, namely industrial gear, vehicle gear and gear equipment. Among them, the market share of vehicle gear reaches 60%; Industrial gear is composed of industrial general, special and special gears, with market shares of 18%, 12% and 8% respectively; Gear equipment accounts for 2% of the market share. During the Tenth Five Year Plan period, the total output value of the gear industry increased from 25 billion yuan to 50 billion yuan, with an average growth rate of nearly 20%. It doubled in five years, ranking fourth in the world. There were more than 50 enterprises with a sales scale of 100 million yuan, and the industry concentration increased significantly. At present, there are a large number of internationally advanced products in five categories, hundreds of series and thousands of products in the gear industry. In 2006, the annual output value of the gear industry was 59 billion yuan, of which vehicle gears accounted for up to 2/3. The driving force of automobile industry is an important support for the development of gear die.

The consumption of gears is huge. Each car has more than 20 gears of different sizes. Most automotive gears are made of gear steel 20CRMNTI, and only a small number of high-end car transmission gears are made of stainless steel, so gear steel is growing synchronously with automobiles, ships, engineering machinery, etc. In addition, the export of mechanical and electrical products drives the demand for gears. In recent years, the export of mechanical and electrical products has increased by more than 30% annually, and the consumption of gears has increased by more than 25%. The market for special and special gear transmission is also large, such as non-circular gears, powder metallurgy gears, small module gears, etc., and the demand for gear steel is also large.

From this point of view, due to the continued release of terminal effective demand during the year, the gear steel market was supported by stable operation and relatively firm prices.

With the increasingly mature gear industry and the continuous development of gear downstream industries, such as the automobile industry, the output value of China's gear industry in 2006-2010 will be close to 100 billion yuan, ranking third in the world and second in the world. From 2011 to 2015, China will strive to rank second in the world.

The domestic gear mold industry is mixed. The good news is that the domestic gear mold production has already had a certain foundation, and the rapid development trend of powder metallurgy gears will also bring greater market vacancy to gear molds. The worry is that compared with the advanced production level of gear molds abroad, there is still a certain gap in the level of domestic production of gear molds. In addition, with the rapid development of the gear industry, especially the plastic gear industry, China's response to market changes is not sharp enough, and supporting research and market demand are a little difficult.
