We offer OEM metal parts & accessories for electornic
appliances , mechanical device machine parts through metal
injection molding process , powder injection molding. Metal
injection molding (MIM) is a hybrid metal fabrication process.
MIM allows for easy shaping of products like plastic injection
molding. It also allows for the materials flexibility of
conventional powder metallurgy. MIM is ideal for the mass
production of small, intricate components. 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: MoldingThe
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: DebindingBinder 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 designersMerge two or more parts into oneMIM can
reduce cost of assembliesGreen part and post-processing for special
requirementsMetal 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.Customized metal parts
