Product Description

We offer OEM metal parts & accessories for  electornic appliances , mechanical device machine parts through metal injection molding powder metallurgy process . 
Metal injection molding (MIM) is a core metalworking process that allows manufacturers to create custom metal parts in complex shapes. MIM enables one to create any kind of metal body. It is primarily employed in the making of small, complex, tailored metal parts that are not readily available in the market and must be custom made. These parts generally weigh less than 100 grams.
The MIM process allows for considerably more design freedom than other metal fabrication processes like die casting. You can choose from almost any combination of metal powder and plastic binders to produce even the most complex shapes.
 

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 :

• No limits for designers
• Merge two or more parts into one
• MIM can reduce cost of assemblies
• Green part and post-processing for special requirements

Metal injection molding was developed in the late seventies and has grown exponentially in popularity as many industries recognized its value.

• Firearms - triggers, safety, magazine catch, fire suppression. 
• Medical device industry - articulation gears, joint replacements, drug delivery devices.
• Automotive - turbocharger vanes, rocker arms, shift levers.
• Consumer electronics - lightning connectors, heat sinks, cold plates, fiber optic parts, and various mobile phone parts.
• Aerospace - flap screws, engine components, valve holders, and rocket burners.
