Our Metal Injection Moulding (MIM) Services

Metal injection moulding (MIM) is a process that merges two established technologies: plastic injection moulding and powdered metallurgy. It is best suited for smaller, high volume metal parts with high strength and wear characteristics that cannot be achieved with other metal production methods.

With our metal injection moulding services, you can produce small and intricate parts from a variety of materials, including stainless steel, titanium, iron and copper at a much lower cost. At HLH, MIM tolerances are controlled to ± 0.05mm or better on request.

Tolerances for MIM

The table below summarises the standard tolerances used at HLH for metal injection moulded parts.

 

Nominal Dimension (mm)Tolerance (mm)
< 3 ± 0.03
 3-6 ± 0.05
 6-15 ± 0.08
15-30 ± 0.15
 30-60± 0.25
>60± 0.5%

Typical MIM Finishing Options

FinishApplicable MaterialsColorDescription
ElectroplatingAll metalsPlated material colorElectroplating is primarily used to change the surface properties of an object (such as abrasion and wear resistance, corrosion protection, aesthetic qualities).
Bead BlastingAll metalsUniform matte of raw material colorBead blasting is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.
PolishingAll metalsPolishing is often used to enhance the appearance of an item, prevent contamination, remove oxidation and create a reflective surface.

How It Works

MIM is a metal working process in which finely-powdered metal is combined with binder material to create a “feedstock” that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step.
