With the continuous progress of science and technology, powder metallurgy processes have undergone more improvements and innovations. For example, the newly added advanced powder metallurgy technologies, such as selective laser sintering and metal 3D printing, have brought more possibilities to the powder metallurgy industry. These advanced technologies can not only achieve higher manufacturing efficiency and more precise forming, but also produce more complex and functional components and products. The following is an analysis of the technical characteristics of the powder metallurgy industry in 2023.
Powder metallurgy can be used to manufacture conductive materials, magnetic materials, and thermosensitive materials for electronic components, in order to meet the needs of electronic products for small size, high precision, and high performance. From the perspective of global market size, according to the in-depth research report on the operation trend and investment planning of China's powder metallurgy industry from 2023 to 2028, the global market size of the powder metallurgy industry reached 26.7 billion yuan in 2021. It is expected that the global powder metallurgy technology market size will reach 27.8 billion US dollars in 2022, reach 34 billion US dollars in 2027, and the compound growth rate from 2022 to 2027 is 4.1%.
By applying advanced computer simulation and data analysis technologies, powder metallurgy enterprises can optimize production processes, improve product quality, and achieve intelligent and automated production. This not only improves production efficiency, but also reduces labor costs and resource waste, bringing more competitive advantages to the enterprise. We will now analyze the technical characteristics of the powder metallurgy industry in 2023 from the perspective of three major industry technologies. 1、 Raw material preparation technology in powder metallurgy industry The raw materials for powder metallurgy are usually metallic or non-metallic materials, and the quality of the prepared powder directly affects the performance of the final product. Common raw material preparation methods include mechanical grinding, chemical method, and physical method. The mechanical grinding method involves grinding bulk raw materials into powder using equipment such as ball mills and high-energy ball mills. The law of chemistry is to reduce metal ions in a solution into metal powders through chemical reactions. Physical methods include gas phase method and solidification method, which prepare powders through evaporation, condensation, and other methods. 2、 Forming Technology in Powder Metallurgy Industry The forming process of powder metallurgy involves pressing the prepared powder into shape and size. The commonly used molding processes include compression molding, injection molding, and extrusion molding. Compression molding is the process of filling powder into a mold, applying pressure to densify it, and obtaining a certain shape of the part. Injection molding involves mixing powder with organic additives, injecting the mixture into the mold through an injection machine, and then curing to obtain the parts. Extrusion molding is the process of mixing powder with organic additives and extruding the mixture into shape through an extruder. 3、 Post processing technology in powder metallurgy industry The post treatment process of powder metallurgy is to treat the formed parts to improve their performance and surface quality. Common post-treatment processes include sintering, heat treatment, and surface treatment. Sintering is the process of heating the formed powder at high temperatures, causing fusion between powder particles and forming dense parts. Heat treatment is the process of controlling the heating and cooling process of a material to change its microstructure and properties. Surface treatment includes electroplating, spraying, polishing, etc. to improve the surface hardness, corrosion resistance, and aesthetics of the parts. In summary, the powder metallurgy industry has the characteristics of high efficiency, energy conservation, diversified material selection, strong precision forming ability, and huge development potential. With the continuous innovation of technology and the expansion of applications, the powder metallurgy industry will continue to grow and play a more important role in various fields.
