Powder Metallurgy, Sinter Metals, Powdered Metals

Powder metallurgy is the process technology of making metal powder or using metal powder (or the mixture of metal powder and non-metal powder) as raw material, through forming and sintering, making metal materials, composite materials and various types of products. Powder metallurgy and ceramic production have similar places, both belong to powder sintering technology, therefore, a series of new powder metallurgy technology 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.
Powder metallurgy includes powders and products. The powder is mainly metallurgical process, and the literal. Powder metallurgy products, on the other hand, are often far beyond the scope of materials and metallurgy and are often multidisciplinary (materials and metallurgy, machinery and mechanics, etc.) technologies. Especially modern metal powder 3D printing, set mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, laser technology in a body, making powder metallurgy products technology become a modern comprehensive technology across more disciplines.

Powder metallurgy bearing

Powder metallurgy oil bearing (oil-bearing) is a kind of porous alloy product with lubricating oil in the pores. When the shaft rotates, the friction between the shaft and the oil-bearing causes the temperature of the oil-bearing to rise and the pumping action. Lubricating oil leaks out of the friction surfaces of the inner or outer diameters of the oil-bearing when the shaft stops rotating. The lubricating oil flows back into the bearing. Therefore, the consumption of lubricating oil is very small and can be used for a long time without an external supply of lubricating oil. Very suitable for oil supply difficulties and avoid lubricating oil pollution occasions.

Oil bearing is widely used in: motor industry, automobile and motorcycle industry, home appliance industry, digital products, office equipment, power tools, textile machinery, packaging machinery, and other types of mechanical equipment.
Generally speaking, powder metallurgy oil-bearing is mainly made of raw material powder through pressing, sintering, shaping, oil immersion, and other processes. Machines are mostly highly automated. Daily output is relatively large, most of the products can be formed at a time, so the larger the batch better the production. And with a little less mold may do hundreds of thousands of words, more words may do more than a million. But the cost of the mold is relatively high, so it is not easy to do if the batch is small, and the time to replace the mold is also long.
Powder metallurgical oil-bearing can generally be formed once, basically without cutting. Cost is lighter than machining, material waste is less, so the price is cheaper. It is also in line with the national policy of promoting energy conservation, so it is considered a technology that will not fall behind The Times.
The matrix of powder metallurgy oil-bearing has been filled with a lubricating oil by vacuum immersion method, and the lubricating oil will ooze out to the running surface due to temperature rise and pumping during operation, so it can be used on occasions without adding lubricating oil.
