Reliable technologies, Lead to the future

ART METAL MFG. CO., LTD. celebrated our 100th anniversary in January 2017.
In 1917, Ikuzo Sakakibara founded ART Co. as an auto-repair shop. After that, we started developing Aluminum light alloy pistons to achieve lighter-weight pistons than cast iron ones. In 1926, for the first time in Japan, we succeeded in prototype production of light alloy pistons for internal combustion engines, and in 1932, we started full-scale production of Aluminum light alloy pistons that were ahead of their time. Also, we invented various original technologies in material, manufacturing, and equipment, and we have been contributing to society as a specialized manufacturer of pistons. This is a result of the support by all of the stakeholders such as customers, trading partners, stockholders and the local communities. We are deeply grateful to you.

In this memorial year, we decided on business integration with Aisin Seiki Co., Ltd. We pass the baton of our founder’s spirit with the mottoes of “elaborate work, originality, and ingenuity” to the next 100 years. We will use this business integration as a springboard to make further progress.
We steadily progress with the reform indicated in our long-term business plan “AI20 (ART Innovation 2020)”. We will strengthen the competitiveness of existing business fields, and create new products and new businesses at the same time, and then, we will continue to contribute to the society.

100 Years of TechnologyTechnology

The World-class Craftsmanship

After we established the auto-repair shop organization, we started developing Aluminum light alloy pistons to achieve lighter-weight pistons than cast iron ones. In the next year, 1926, for the first time in Japan, we succeeded in prototype production of Aluminum light alloy pistons for internal combustion engines through the alloy iron casting method.

The history of ART pistons started here. To this day, we have continued to seek out the new challenges of ideal pistons.
Our corporate culture, which is building production facilities by ourselves, i.e. “in-house production” since its inception, makes possible the flexible and efficient manufacturing and it is our characteristic.

Thoughts on CraftsmanshipThink About

Yuichi AmariJoined in 2012 Production Engineering Division

This company is a specialized manufacturer of pistons, and we celebrated our 100th anniversary this year. I am very happy to be here for this monumental major milestone.
I am currently in charge of designing pistons, studying every day to supply high performance pistons to our customers all over the world. I feel even more motivated because I can design and develop pistons in this company that has over 100 years of history. Because the test and evaluation facilities in this company can conduct tests and evaluations that cannot be carried out by car manufacturers, I am deeply impressed with this company’s ravenous appetite for craftsmanship.
We aim to be tops in the world through advanced technologies and excellent craftsmanship, and aim to be a company that is constantly innovating.

ART METAL MFG. CO., LTD., beloved by many and nicknamed “ART-san” by local people, celebrated the 100th anniversary in 2017.
I joined this specialized piston manufacturer in April six years ago, and now I am in charge of the data entry of purchase orders, managing attendance, and polishing the cutting tools that are used in the manufacturing process as a support person. I think it is very valuable that I, with only 6 years of experience, could have the opportunity to contribute to various matters in a company that has been around for a hundred years, and I feel more challenged at work.
As we head into the next 100 years, I will never forget my feelings of gratitude toward everyone, and I will try to further improve myself and make a new start with this company.
