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.

Customized metal parts specification
 

PM Process has a high degree of flexibility allowing the tailoring of the physical characteristics of a product to suit your specific property and performance requirements. These include:

• Structural pieces with complex shapes
• Controlled Porosity
• Controlled performance
• Good performance in stress and absorbing of  vibrations
• Special properties such as hardness and wear resistance
• Great precision and good surface finish
• Large series of pieces with narrow tolerances
