What are the advantages of powder metallurgy sintered parts

What are the advantages of powder metallurgy mechanical structural parts?

1. Since the powder metallurgy method can be pressed into a green compact of final size without or rarely requiring subsequent machining, it can save metal to a great extent and reduce product costs. When products are manufactured by powder metallurgy, the loss of metal is only 1-5%, while when produced by general melting and casting, the loss of metal may reach 80%. 2. Since the powder metallurgy process does not melt the material during the material production process, it is not afraid of mixing impurities brought by the crucible and deoxidizer, while sintering is generally carried out in a vacuum and reducing atmosphere, and is not afraid of oxidation. German powder metallurgy electric vehicles Customized parts will not pollute the material, so it is possible to produce high-purity materials, German powder metallurgy electric vehicle parts customization. Deburring process of powder metallurgy parts: According to the characteristics of powder, the structure of parts and the material of mold, etc., the clearance of mold should be reasonably controlled.

Surface treatment process of powder metallurgy parts: electroplating of powder metallurgy products is for rust prevention and aesthetics, but because powder metallurgy products have porous characteristics, if electroplating is required, it is necessary to find a high-quality powder metallurgy sealing manufacturer, and then find a powder Metallurgical electroplating manufacturers. Generally, these two manufacturers will not do it together. Of course, you can also ask the powder metallurgy manufacturer to do it directly. Powder metallurgy parts, especially iron-based parts, are coated with a layer of zinc, nickel, chromium, or copper, which is very beautiful and does not rust, so more and more electroplating methods are used. However, the electroplating of powder metallurgy parts is difficult, the main reason is that there are pores in the parts. For direct electroplating of powder metallurgy parts, the surface quality is very poor, and there are too many pores that cannot be plated, and the electroplating solution that penetrates into the pores cannot be cleaned, causing internal corrosion. Therefore, powder metallurgy parts need to be sealed before electroplating, that is, to seal the pores on the surface of the parts. After the powder metallurgy parts are sealed, the electroplating process is stopped. The electroplating process is: powder metallurgy parts (dry at 180°C) - chemical degreasing (2min) - electrolytic degreasing (2min) - hydrochloric acid solution corrosion - (1min) - NaCN (10 %)-Copper cyanide (2h I need)-hydrochloric acid solution corrosion (20%)-zinc plating (on demand)-nickel plating (on demand)-chrome plating (on demand)-hot water washing-drying. Advantages of customized powder metallurgy mechanical structural parts in Jilin powder metallurgy accessories: save metal to a great extent and reduce product cost.

Two pressing methods of powder metallurgy parts: I believe everyone knows that pressing molding is an important process in the processing of powder metallurgy parts, so what are the methods of pressing parts? The pressing methods of powder metallurgy parts are one-way pressing and two-way pressing . Because of the different pressing methods, the internal density distribution of the product is different. To put it simply, for one-way pressing, the pressing force decreases as the distance from the punch increases due to the friction of the inner wall of the mold, and the density changes with the pressure. Lubricants are generally added to the powder to facilitate pressing and demolding. The lubricant reduces the friction between the powders and increases the density quickly during the low-pressure stage of the pressing process. But in the high-pressure stage, since the lubricant is filled in the gaps between the powder particles, On the contrary, it hinders the compactness of the product. The control of the release force of the product avoids the surface defects of the product caused by the release process. During the pressing process, it is very important to confirm the weight of the product, because the air pressure in many factories is unstable, which will lead to a large difference in the weight of the product, which will directly affect the performance of the product.

Powder metallurgy structural parts used in automobiles: With the increasing demand for automobiles, the automobile industry has developed by leaps and bounds. Of course, this demand has also promoted the development of powder metallurgy auto parts industry. Due to the advantages of powder metallurgy and relatively low cost, powder metallurgy materials are more and more commonly used in auto parts. Automobile compressor parts: Automobile compressor parts include a series of parts such as cylinders, cylinder heads, valves, valve plates, crankshafts, connecting rods, and piston rods. The use of powder metallurgy parts for automotive compressors is also a comprehensive consideration of its advantages: powder metallurgy processing can use molds for mass production, the products are uniformly formed, and alloying elements can be added to the raw materials to enhance the performance of the product. Powder metallurgy has higher processing precision, and can be formed in one step without cutting, which can save costs. The blackening treatment of powder metallurgy parts is a common method, which is to produce a layer of oxide film on the surface of metal parts to isolate the air and achieve the effect of rust prevention.

What are the industries covered by powder metallurgy parts? Powder metallurgy gears are powder metallurgy parts commonly used in various automobile engines. Through one-time forming and finishing process, no other post-processing process is required, and the dimensional accuracy requirements can be fully met, especially Tooth profile accuracy. Therefore, compared with the traditional mechanical processing method, the material input and manufacturing are greatly reduced, and it is a typical product that embodies the characteristics. Supporting examples of powder metallurgy parts Supporting category Parts name: automobile engine; camshaft, crankshaft timing pulley, water pump, oil pump pulley, driving and driven gear, driving and driven sprocket, cam, bearing cover, rocker arm, Bushings, thrust plates, valve guides, intake and exhaust valve seats, automotive gearboxes; various high and low speed synchronizer gear hubs and components, clutch gears, cams, camshafts, sliders, shift levers, bushings, guides piece. The influence of burrs on powder metallurgy parts on product quality: affect the heat treatment performance of products. Xiamen powder metallurgy electric vehicle parts customization

The impact of burrs on powder metallurgy parts on product quality: the existence of burrs will inevitably lead to positioning errors, which will affect the machining accuracy of holes. Xiamen powder metallurgy electric vehicle parts customization

What are the advantages of powder metallurgy mechanical structural parts? With the development of my country's industrial industry, mechanical structural parts produced by powder metallurgy have the advantages of less/no cutting, and are suitable for mass production; they can meet the performance requirements of structural parts for different purposes. Therefore, powder metallurgy has been widely used . 1. Powder metallurgy is suitable for producing a large number of products with the same shape, especially for products with high processing costs such as gears. Manufacturing by powder metallurgy can greatly reduce production costs. 2. The powder metallurgy method can improve the correctness and uniformity of the material composition ratio. Most refractory metals and their compounds, pseudoalloys, and porous materials can only be manufactured by powder metallurgy. German powder metallurgy electric vehicle parts customization.
