Copper products are often employed as terminal or heat sink in the electronics industry due to its high

conductivity or thermal conductivity properties, respectively. Recently, a special nozzle for high-

temperature fluid injection is also made of Cu, where required strict control of both temperature and

injection.

It is increased the demand for smaller and more complicated designed copper product these days. In

conventional MIM, it is difficult to produce copper or copper alloy product because the mechanical

property or conductive property is affected negatively during the debinding and sintering process.

However, μ-MIM® technology optimised the binder system for copper production and realises the serial production of a copper product. Surely, the tight tolerance requirement or complicated hollow design will be accepted as other material μ-MIM® production.

Additionally, originally developed diamond-copper composite, extra high thermal conductivity, serial production is also available.

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.

Manufacturing section: Taisei Kogyo Co., Ltd., TAISEI KOGYO(THAILAND) CO., LTD.

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.
