Product Name: Massage Chair gear transmission block above products produced by powder metallurgy process is made of iron, copper powder. Powder product itself has the powder special oil-bearing function, so that the finished product with its own antirust assistance functions and wear, effectively extending the life of the product. And powder iron base pieces after post processing, such as fine grinding, black, oil-soaked, sintering role, so that products can play a rust-proof, aid slow oxidation, the contact surface wear and appearance beautification (deburring) and good wear resistance, rust resistance and high natural corrosion resistance by customer drawing production, welcome to inquire more product Packing: carton packing mode of transport: Division I (Guangdong province amounted to standard delivery) Delivery period: from the day of the orders within 10 days, 15 days, 30 days on mode of sample delivery cycle: 15 days, 20 days, 25 days, 30 days. powder metallurgy process, powder metallurgy products and products About style metal powder such as: iron powder, copper powder, stainless steel powder include mixed with non-metallic powder) as raw material production from forming - sintering method, the traditional process: mixing - pressing - sintering - plastic surgery - post-processing, that is, first of all the preparation of high purity mixed powder loaded with mold, to suppress certain pressure forming, and then the green compacts in a controlled atmosphere furnace to be sintered at a temperature below the melting point of the matrix material, forming a metallurgical bond between the powder particles in the powder metallurgy process, the advantages of: 1. unwanted or only a very small amount of cutting processing, material shift rate can be as high as 97%, 3. part size smaller manufacturing tolerances and reproducible, 4. adjustable material composition, 5. part surface finish preferably, 6 to improve the strength through heat treatment and abrasion resistance, for using self-lubricating or filtration, available materials or products having a controlled porosity, can be manufactured of other metal forming process can not be manufactured, the complex shape or peculiar parts, 9. adapted Medium to high-volume parts production.
