Product Description

Powder injection molding process for machinery parts 

Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a"feedstock" that is then shaped and solidified using injection molding.The ability to combine several operations into one process ensures MIM is successful in saving lead times as well as costs, providing significant benefits to manufacturers. The metal injection molding process might be a green technology due to the significant reduction in wastage compared to "traditional" manufacturing methods.

Metal injection moulding process custom metal parts 

The advantages of metal injection molding for metal fabrications :

• Highest degree of design freedom for complex shapes and geometries
• Provides practical economic solutions to increasingly stringent material and product design requirements
• Functional integration of various features, such as lateral drillings, interior and exterior threads and gear teeth.
• Excellent batch to batch repeatability with exceptional process capabilities
• Very high volume production series run on fully-automatic injection molding machines using multi-cavity tools
• Components can be heat and surface treated, plated, welded and soldered

Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.

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.
