Adaptability to complex shapes, the strength of sintered components

Sintered alloy is processed by the powder metallurgical method (PM), a technique that compresses and molds fine powder of multiple metals including iron and bakes it at a high temperature. It is suitable for manufacturing components with complex shapes and, by changing the ratio of alloying materials, it enables the creation of alloys of various compositions. Due to these characteristics, sintered parts are used in various industrial fields including automotive parts, office equipment, and household appliances.

Joint development with customers promoted by PM Engineering Center

Although it already has the largest market share of sintered parts in Japan, aiming for further growth, the company established the PM Engineering Center (PMEC) in May 2013 to demonstrate its technology and support system and to function as the “global mother” technical center. The center is equipped with evaluation facilities for products and materials, which have enhanced the capability for joint product development with customers and contributed to the growing number of orders. The center holds workshops for customers and invites them on factory tours.

Accelerating its global expansion, the company established a new manufacturing and sales base in Mexico in August 2014. The construction of a second Thailand factory is also planned. In this situation, enhancement of the function as the global mother company in the group is desired. While respecting the uniqueness of individual overseas base, to be able to stably provide the same quality products to customers all over the world, the company is continuing its efforts to promote communication among the engineers of each manufacturing site, so that standardized techniques, facilities, and quality is ensured among different locations.

President’s message

Tetsuya Hayashi, Representative Director and President
Tetsuya Hayashi, Representative Director and President

“The fighting mother plant,” is the slogan of our company, which aims to grow in the domestic market and enhance the governance of overseas manufacturing. Aiming for increased capacity to receive orders, generate profits, and enhance quality assurance, the head office will function as the global mother plant and fully support overseas affiliated companies. Currently we have the largest market share in Japan and the second largest market share in the world. For 2020, the year of the Tokyo Olympics, we have set a target to obtain the largest market share in the world.

Factory tours with elementary school pupils

Factory tours with elementary school pupils

As part of its contribution to the community, the main plant provides factory tours for pupils from local elementary schools. After the tour of the manufacturing process, President Hayashi places medals made of sintered alloy onto the participants. The participants are always very excited at the event and we receive many reports from the pupils describing how much they enjoyed the experience.
