We offer OEM metal parts & accessories for electornic appliances , mechanical device machine parts through metal injection molding process , powder injection molding.
Powder Injection Molding (PIM), comprising Metal Injection Molding (MIM) and Ceramic Injection Molding (CIM), is an advanced manufacturing technology for the production of complex, high volume net-shape components.
You can find the products of this industry, with global sales in excess of $2 billion a year, applied in all areas of life, from medical devices, to automotive and aero engines, watches, power tools, orthodontics and consumer electronics.
The range of application of metal injection moulding and sinter-based additive manufacturing - both methods offering great freedom to realize even most complex geometries- can be extended by green part processing or post-processing of sintered components.
Greelife will highlight the possibility of merging several parts in one component and explain how the potential of the two manufacturing technologies can be increased: Green part processing for instance through lasering and machining, post-processing of sintered parts by applying technologies like hot isostatic pressing, polishing and coating.
- No limits for designers
- MIM can reduce cost of assemblies
- Merge two or more parts into one
- Green part and post-processing for special requirements

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.
