Longhua non-standard powder hardware processing

powder metallurgy is a process technology for making metal powder and making metal powder into products by forming and sintering technology. With the continuous development of modern technology, various new processes have emerged one after another, and have also been widely used. Powder metallurgy is suitable for producing a large number of products with the same shape, especially gears and other products with high processing costs. The production cost can be greatly reduced by using powder metallurgy. The production process of our powder includes the preparation of powder, the mixing of powder and so on. Many times, in order to improve the plasticity and formability of our powder, we usually add plasticizers such as gasoline, rubber or paraffin in the production process

powder metallurgy is a process technology of making metal powder or using metal powder (or the mixture of metal powder and non-metallic powder) as raw material, forming and sintering, and manufacturing metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, which belongs to powder sintering technology. 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 solve the problem of new materials and plays an important role in the development of new materials

the production of powder metallurgy parts used by Longhua in our cars is still based on the cold molding sintering process. Although the accuracy, recheck degree, performance stability and cost of its products have made some progress, the low part density affects the performance of parts, especially the improvement of mechanical properties

powder metallurgy molding technology is a powder metallurgy technology that uses rapid solidification to prepare large and dense metal materials. It is a near net forming technology for preparing metal and ceramic parts with three-dimensional complex shapes. It is an efficient and environmental protection technology for preparing various metal and ceramic high-performance parts. Some gears are made by forging. The internal structure density of forged gears is better and the strength is higher. Forged gears can be used in more stringent working conditions. Precision parts made of metal powder have many new applications in the fields of automobile, chemical industry and aerospace

with the increasing competition in the gear industry, mergers and acquisitions and capital operations among large gear enterprises are becoming more and more frequent. Domestic excellent gear manufacturing enterprises pay more and more attention to the research on the industry market, especially the in-depth research on the development environment of enterprises and the changes of customer demand trends. Because of this, a large number of domestic excellent gear brands have risen rapidly and gradually become the leaders in the gear industry! In 2011, the overall sales volume of the gear industry reached 178 billion yuan, an increase of 23% year-on-year; Although the import volume is still much higher than the export volume, the export growth rate is significantly stronger than the import

green body made of Longhua powder metallurgy and its forming method and application this patent technology relates to a metal green body, in particular to a green body made of powder metallurgy material, used for manufacturing cutting tools, and the forming method of the green body. Technology introduction powder metallurgy is the process technology of making metal powder or using metal powder (or the mixture of metal powder and non-metallic powder) as raw material, forming and sintering, and manufacturing metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, which belongs to powder sintering technology. Therefore, the working conditions of powder metallurgy technology materials are very complex, and technology can also be used for the preparation of ceramic materials. The development of gear theory and manufacturing technology will further study the mechanism of gear tooth damage, which is the basis for establishing a reliable strength calculation method, and the theoretical basis for improving the bearing capacity and prolonging the service life of gears; Develop new tooth profiles represented by circular arc tooth profiles; Study new gear materials and new technology of manufacturing gears; The economic and trade cooperation between Hainan and ASEAN has developed rapidly. The elastic deformation, manufacturing and installation errors and the distribution of temperature field are studied. The gear tooth modification is carried out to improve the stability of gear operation, and the contact area of gear teeth is increased at full load, so as to improve the bearing capacity of gears

bearing parts have to go through many cold and hot processing procedures in the consumption process. In order to meet the requirements of a small amount, high efficiency and high quality, bearing steel should have good processing performance. The broad sense of powder metallurgy products industry includes iron ore cutting tools, cemented carbide, magnetic materials and powder metallurgy products. In a narrow sense, the powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts (accounting for the vast majority), oil bearing and metal injection molding products. The single marketing is due to the fact that commercial vehicle parts enterprises are limited by regional segmentation, which determines that they can only maintain customer relations through a point-to-point model. The problem of capital also determines that it is difficult for spare parts enterprises to invest a lot in technology research and development. The national repeated construction has made the spare parts enterprises fall into the mire of price competition, which has caused a serious waste of capital. A complete cake is fragmented, so it is difficult to form a large concentrated body made by attaching plastic additives to the resin in an extraordinary amount; The large-scale production of plastic products makes their profitability stagnant, and it is difficult to invest heavily in subsequent research and development. Cemented carbide is a kind of powder metallurgy product, which is sintered in vacuum furnace or hydrogen reduction furnace with carbide (WC, TIC) micron powder of high hardness refractory metal as the main component and cobalt (CO) or nickel (Ni), molybdenum (MO) as the binder. It also belongs to a class of powder metallurgy materials

in addition, carbides, nitrides, borides, etc. of IVB, VB, VIB metals are also collectively referred to as cemented carbides because of their extremely high hardness and melting point. Cermet in order to make ceramics not only resistant to high temperature but also not easy to break, people add some metal powder to the clay used to make ceramics, so cermet is made, which also belongs to a kind of powder metallurgy material. In life, we know that many products are made of stainless steel, and the traditional process of manufacturing stainless steel products, smelting process, due to the difficulty of cutting and processing, leads to some products with poor dimensional accuracy, insufficient surface roughness and other waste plastic granulator, which is very easy to cause environmental pollution during the operation process. In order to solve this problem, people began to use stainless steel powder metallurgy manufacturing. Stainless steel powder metallurgy played an important role in solving the production problem of stainless steel products. Stainless steel powder metallurgy solves the production problems of stainless steel products and its advantages are inseparable. Then, what are the advantages of stainless steel powder metallurgy to solve the production problems of stainless steel products

the ceramic phase in Longhua non-standard powder metal processing cermet is oxide or refractory compound with high melting point and high hardness, and the metal phase is mainly transition elements (iron, cobalt, nickel, chromium, tungsten, molybdenum, etc.) and their alloys. Metal based cermets are made by adding fine oxide powder into the metal matrix, also known as dispersion reinforcement materials, such as sintered aluminum (aluminum alumina), sintered beryllium (beryllium beryllium oxide) and TD nickel (nickel thorium oxide). A composite material consisting of one or more ceramic phases and metal phases or alloys
