Which molding technology is better, powder metallurgy processing or pressure processing?
Due to its great technical and economic advantages, powder metallurgy is widely used in the national economy. It can be said that no industrial sector does not use powder metallurgy materials and products. Do you know which molding technology is better, powder metallurgy processing or pressure processing? The following is the share of zhongwei precision editor.
1： Powder metallurgy processing technology
1: Higher product accuracy
Powder metallurgy processing technology can produce nanocrystalline, microcrystalline, amorphous and other balance materials with very high performance and high precision requirements. These materials have excellent performance in electrical, optical, magnetic and mechanical aspects, so powder metallurgy technology is also a process technology to solve the problem of new materials at present.
2: Complex parts can be produced in batches
Powder metallurgy processing technology can batch produce various parts with special shapes and complex shapes, and adopt mold for batch production, with less processing volume and low production cost, especially for the production of various gear parts.
3: Can produce special materials
Powder metallurgy processing technology can produce new porous biomaterials, porous separation membrane materials, high-performance structural ceramics and functional ceramic materials that cannot be produced by ordinary smelting technology, which also proves the ultra-high value of powder metallurgy and is also the necessity of the development of the times.
4: Material can be reduced
Powder metallurgy processing technology uses molds that are very close to the final product shape in the forming process, so the amount of product processing is small, and it can save materials, avoid material waste, and also reduce production costs.
5: Waste metal as raw material
Powder metallurgy processing technology can make full use of tailings, ore, steel mill scale, steelmaking sludge, waste metal recovery and other raw materials to achieve material regeneration and comprehensive utilization of new molding processing technology, which has been widely used in various fields.
2： Pressure processing technology
The pressure processing technology is mainly a processing method of plastic forming of sheet metal by means of dies. The required shape is formed by changing the spatial position of the area of each part of the blank.
1: Save raw material waste
Pressure machining technology can reduce or eliminate machining, and the utilization rate of raw materials is relatively high. It can improve the mechanical properties of the metal. Under the same stress and working conditions, it can reduce the section size of the parts, reduce the weight and extend the service life.
2: High mechanical properties
The structure of pressure processing technology leads to the improvement of material structure, performance, strength, hardness and toughness.
The disadvantages of traditional processing technology, such as the difficulty to complete the modeling of complex parts in large quantities, are precisely the advantages of powder metallurgy. The traditional pressure processing technology is huge in equipment, expensive in manufacturing, and easy to oxidize the surface of the general process. Therefore, modern small and medium-sized parts forming technology is basically powder metallurgy technology, except for some very large parts.
