This is an OEM pure copper component example used in medical equipment. The component has several convexoconcave and penetrated holes. Each of the 3 terminals has 0.7mm or 0.9 mm in hole diameter (the pipe diameter is 1.5 mm) with 4 mm depth.
The client has required tight tolerance and good conductivity for this component. In conventional machining, pure copper is one of the difficult-to-cut material, unlike brass. Therefore productivity becomes a problem in this case.
On the other hand, MIM has good productivity in pure copper. However, its metal powder is mixed with the organic material as a binder for forming, and it has made it difficult to control the contamination, which reduces the conductivity.
Our μ-MIM® technology optimises our binder for each material, thus it realises also the serial production of pure copper material with good conductivity.
Additionally, it satisfies with the tight tolerance requirement, 0.01 mm tolerance range (with smallest powder size), while conventional MIM achieves only 0.03 mm.
If you are looking for small complicated designed pure copper component manufacture, please contact us.
We will provide you with the best solution to create innovative metal components that were impossible to mass-produce.

Micro MIM Japan Holdings Inc. and its group companies cooperate as a team to cater for various needs of our customers from different parts of the world.
Taisei Kogyo Co., Ltd. was established in January 1972 as a plastic injection moulding manufacturer. Aside from improving our technology in the plastic injection moulding, we organised an R&D group in Kyoto Research Park about 25 years ago, to start researching on MIM technology. We utilise our knowledge and experience from the plastic injection moulding and developed original MIM material (binder system and feedstock), which makes it possible to manufacture small and complex shaped MIM components for serial production. Taisei Kogyo Co., Ltd. has obtained ISO13485 in May 2019. TAISEI KOGYO (THAILAND) CO., LTD. was established in August 2011 and started its operation in 2012. We maintain the same production standard as Japanese factory.
