Product Description

We offer OEM metal parts & accessories for  electornic appliances , mechanical device machine parts through metal injection molding process , powder injection molding.Finishing and Refining .
Metal Injection Moulding - MIM - offers the strength of metal with the geometric possibilities of plastic. An MIM component can replace a plastic component, or possibly 2-4 metal subcomponents made using other metalworking processes.

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.

In subsequent refining processes all conceivable heat and surface treatments can be carried out analogously to conventionally-manufactured components. The finishing competences of Greelife go well beyond the scope of common finishing procedures. We help you to decide on a case-to-case basis which refinement measures are technologically and economically optimal for your product and application.We deliver finished, ready-to-install components.
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.

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.

Typical characteristics and applications of metal injection-molded parts.As mentioned above, typical metal injection-molded parts are small and complex in nature. The process is more advantageous for more complex parts. In this process, high precision is possible to achieve. This method eliminates the constraint imposed by conventional powder metallurgy methods i.e. the side wall should be parallel. Very small size parts i.e. smaller than a golf ball in volume, weigh in the range of 0.5 to 150 g, and a wall thickness of less than 6.3 mm can be achieved using this method. It is possible to produce multi-functional parts with thin walls, sharp corners, undercuts, cross holes, screw threads, contours, gear segments, and similar features without secondary operations.

At Greelife, processing parameters for the following material classes have been developed:

• Stainless steels, low-alloy steels
• Heavy metals based on tungsten
• Intermetallic materials
• Magnetic materials
• Case hardening steel and tempering steel
• Nickel-based materials
• Light metals based on titanium
• Noble materials
