Product Name: more precision gear 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, applicable to various types of office equipment, lifting gear Product Package: carton modes 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 mold of sample delivery period: 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 including mixed with non- metal powder) as raw material, the production from forming - sintering method, the traditional process: mixing - pressing - sintering - plastic surgery - after processing, high purity mixed powder loaded with mold that is first formulated in press-forming under a certain pressure, and then the green compacts in a controlled atmosphere furnace, and sintered at a temperature below the melting point of the matrix material, forming a metallurgical bond between the powder particles of the powder metallurgy process, the advantages of: 1. unwanted or only a very small amount of machining, 2 Materials shift use rate can be as high as 97%, 3. part size smaller manufacturing tolerances and with reproducibility, 4. adjustable material composition, 5 parts of the surface finish is preferably 6. by a heat treatment to improve the strength and abrasion resistance, with a 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 suitable for medium to large-volume parts production.
