What is μ-MIM®?
The 4 best reasons to manufacture high-precision components with μ-MIM®
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.
This is due to our original feedstock processing, which we developed based on our knowledge and experience in plastic injection moulding history.
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.
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
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.
What we can offer our clients
Broadest range of materials
Stable serial production
Parts smaller than a grain of rice
High accuracy, density, strength and surface quality
High surface quality
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 plastic mould is produced and placed in the mould to be inserted; the SP mould is completely disassembled in a process of debinding and sintering and finally becomes a 100% metal component.

How we help you solve your technology challenges
Because the shape of the component was too complex to make at once, multiple parts were made separately and then had to be assembled into a single part.
We can produce parts in a net shape using a die in an integrated mould, which helps to reduce costs and shorten delivery time, and also leads to downsizing.
Because the material had a complex shape and was difficult to process, companies refused to produce it.
We are able to produce components with complex shapes and materials that are difficult to machine, this way we can make a valuable contribution to the development of completely new products
Burrs, etc. were produced, post-processing was necessary, and the yield rate was low.
The realisation of net-shape has made post-processing unnecessary and enabled highly accurate production.
Machine processing reached its limits in mass production, so that the component could not be produced in the desired quantity.
We offer manufacturing in dimensions that cannot be achieved by machining, both in terms of quantity and shape, resulting in lower costs and shorter delivery times
