Benefits of μ-MIM®

What is μ-MIM®?

With our technology, we are able to produce metal components that would not be possible with conventional MIM manufacturing methods. We can produce very small parts with complex shapes from a wide range of materials in large quantities with high precision and quality.

With over 50 years of experience in the industry and more than 25 years of research and development, we are your trusted partner for medical device components as well as parts in the semiconductor and precision industries.

The 4 best reasons to manufacture high-precision components with μ-MIM®

High tolerance

The precision level of μ-MIM® technology is almost identical to machining.

With over 25 years of our original μ-MIM technology development, we have achieved unprecedented tolerance satisfaction in an as-sintered state. In conventional MIM, the tightest tolerance is +/- 30 μm, while μ-MIM® achieves +/- 10 μm.

Compared with the latest machining technology, the tolerances achieved are lower, but still competitive with conventional machining. Plus, μ-MIM® technology is a net-shape production technology that uses minimal post-processing to reduce the risk of tolerance deviations in 3D locations. Productivity and preciseness are μ-MIM® technology's unique strengths, which help realise your ideal metal part production to the market.

Material varieties

μ-MIM® offers you a broad range of materials in the MIM industry.

This is due to our original feedstock processing, which we developed based on our knowledge and experience in plastic injection moulding history. We make binder by ourselves.

Since our lead time for feedstock development could be relatively short, newly developed alloy powder can also be used for production, provided the right size and shape of powder is available for procurement.

We are capable to optimise the feedstock for each product's stable production, and newly developed alloy powder can also be used for production.

Design freedom

Our 3D-μMIM® technology has been designed to support the high level of design freedom you have come to expect from traditional MIM.

μ-MIM® technology was developed with a focus on serial production of small complex designs, thus with a minimum of additional machining production has been realised.

Because μ-MIM® technology was developed with a focus on serial production of small complex designs, we are able to produce small features or impossible to demold designs with a minimum of additional machining.

Additionally, our 3D-μMIM® technology achieves even a high level of design freedom that you have not expected from traditional MIM.

Our μ-MIM® and 3D-μMIM® technology realise your difficult-to-machined design serial production.

Stable mass production

Our careful quality control ensures stable serial production in the requirements of dimensions and mechanical properties.

We know that the production of small, complex metal parts requires even better process control than conventional MIM, because the quality of the preceding step has an even greater influence on the parameters of the following step.

The production of small, complex metal parts requires good uniformity in a feedstock pellet since the product size can be smaller than a pellet size.

We have precisely controlled our production process from feedstock to sintering, plus the final dimensional measurement process under the certified ISO 13485 quality assurance system.

Differences between MIM and μ-MIM®

3D-μMIM® Technology

3D-µMIM® is our unique lost-core process that enables the mass production of components with complex geometries with hollow structures and undercuts that are difficult to fabricate using conventional MIM or machining.

First, a sacrificial plastic mould (SP mould) is produced in a mould and inserted into another mould; the SP mould is completely disassembled during debinding and sintering, and a 100% metal component is manufactured in the end.
