Product Description

Powder metallurgy (PM) is a metal parts / components fabrication way and made from metal powders material . The process of powder metallurgy (PM) is blending fine powder materials , press them into a desired shape or form compacting , and heating the compressed material in a controlled atmosphere to bond the material sintering .PM process can avoid , or greatly reduce the need to use metal removal processes,thereby drastically reducing yield losses in manufacture and oftern resulting in lower costs .
The powder metallurgy (PM) consist three steps : powder blending,compaction and sintering .Common products include gears , structural metal parts , bushings used for automobiles , appliances and powder equipments .Powder blending,a homogeneous alloy powders is prepared. Depending the requirement character other alloys and lubricants may be added .Compaction,a controlled amount of the mixed powder is put into a precision die and pressed at a controlled pressure.The compacting pressure required depends on the characteristics and shape of the particles, the powder mixing ,and the lubricant used. In doing so,the loose mixing powder is consolidated and densified into a shaped model. As is comes out of the die , the part has the size and shape of the part.Sintering,the compact part is heated in a protective atmosphere furnace to a suitable temperature and the temperature is below the metal melting point .

Mixing of powders
This can often involve the introduction of alloying additions in elemental powder form or the incorporation of a pressing lubricant.

Forming of the mixed powder into a compact

The dominant consolidation process involves pressing in a rigid toolset, comprising a die, punches and, possibly, mandrels or core rods. However, there are several other consolidation processes that are used in niche applications.

Sintering of the compact to enhance integrity and strength

This process step involves heating of the material, usually in a protective atmosphere, to a temperature that is below the melting point of the major constituent. In some cases, a minor constituent can form a liquid phase at sintering temperature; such cases are described as liquid phase sintering. The mechanisms involved in solid phase and liquid phase sintering are discussed briefly in a later section.

Secondary operations

The application of finishing processes to the sintered part. In the Powder Metallurgy industry, such processes are often referred to as secondary operations.
