Metal Injection Molding (MIM) - sometimes called Powdered Injection Molding (PIM) - is an advanced metal forming technique that uses injection molding equipment for manufacturing both simple and complex metal parts to tight tolerances.  MIM can be used across a wide range of components, but the best applications are typically small and weigh less than 100 grams, though larger parts are possible.  The MIM process can replace other metal forming techniques such as investment casting and machining.

Step 1:  Feedstock 

• Very fine metal powders are combined with thermoplastic and wax binders in a precise recipe. A proprietary compounding process creates a homogenous pelletized feedstock that can be injection molded just like plastic. This achieves ultra-high density and close tolerances over high-production runs. 

• Unlike standard powder metallurgy, which can achieve only 80-90% of theoretical density, MIM results in 95-100%. This means we can achieve close tolerances and reduce costs by producing small, complex parts over high production runs.

Step 2: Molding

• The feedstock is heated and injected into a mold cavity under high pressure. This enables us to produce extremely complex shapes and allows for shorter cycle times.
• Once molded, the component is referred to as a "green" part. Its geometry is identical to the finished piece but is about 20% larger to allow for shrinkage during the final sintering phase.

Step 3: Debinding

• Binder removal (debinding) involves a controlled process to remove most of the binders and prepare the part for the final step - sintering.
• Once debinding is complete, the component is referred to as "brown."

Step 4: Sintering 

• The brown part is held together by a small amount of the binder, and is very fragile.
• Sintering eliminates the remaining binder and gives the part its final geometry and strength.
• During sintering, the part is subjected to temperatures near the melting point of the material.

The advantages of  Powder metallurgy, metal injection molding for metal fabrications :

Greater design freedom
With MIM, parts can be designed and manufactured with minimal design restrictions. In addition, almost all design changes are possible within the shortest development cycle and turnaround time.
Complex and intricate shaped parts
MIM is ideal for producing complex-shaped components as well as parts that require assembly or multiple steps to put together.
Miniaturization
MIM technology is the best viable process for producing miniature parts economically.
High production requirements
MIM is most beneficial in high volume production of small precision parts with complicated design geometry. The process lends itself to automation where high volumes and consistent quality are required.
