Current Status of Powder Metallurgy
Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, which are formed and sintered to produce metal materials, composites, and various types of products. Powder metallurgy has similarities with ceramic production, therefore a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a pivotal role in the development of new materials. China's powder metallurgy industry has experienced nearly 10 years of rapid development, but there are still several gaps compared with foreign counterparts

Future prospects of powder metallurgy gears
Although the powder metallurgy industry has experienced nearly 10 years of rapid development, there are still several gaps compared with foreign counterparts: many enterprises, small scale, and significant differences in economic benefits compared with foreign enterprises. Product overlap, enterprises undercutting each other, and fierce competition. Backward technology and supporting facilities. Few product exports and poor trade channels. After China's accession to the WTO, the above-mentioned shortcomings and weaknesses will be improved, because after joining the WTO, the market will gradually become internationalized, and the powder metallurgy market will have further opportunities for expansion; at the same time, with the inflow of foreign funds and technology, powder metallurgy and related technical levels will inevitably improve.

Recently passed acceptance in Nanchang, presided over by the Jiangxi Provincial Department of Science and Technology. The successful development of this project has laid a solid theoretical and experimental foundation for promoting the progress of injection molding technology in China and improving the gas-assisted injection molding process for plastic product enterprises. Experts believe that this project has pioneered relatively mature theoretical and experimental research on gas-assisted injection molding at home and abroad, establishing a mathematical model of the gas-assisted injection molding filling process for three-dimensional thin-walled parts. The independently developed gas-assisted injection molding injection control system software based on the Windows platform is highly practical and can simulate the injection molding process to identify molding process defects in advance. At the same time
