Highly functional metal materials, primarily copper, stainless steel, titanium, and aluminum.

These materials are both sturdy and flexible, and are indispensable for commercializing cutting-edge technologies and designs.

For example, digital devices that are evolving with the times, such as the smartphones and tablets which have become familiar in everyday life, use highly functional metal materials that serve different roles, in their delicate internal parts and beautiful exteriors.

We support manufacturing that supports our lives and contributes to society by providing highly functional metal materials that are essential for creating new value.

Our network of processing manufacturers has supported manufacturing endeavors over time through our knowledge and experience in the area of non-ferrous metal materials cultivated over more than 70 years since our founding as well as through the supply of highly-functional metal materials.

To enable ourselves to fully leverage our advantages in that manufacturing network in order to meet a diverse array of customer needs in the area of non-ferrous metal materials, we will also take on the challenge of manufacturing services in our capacity as a trading company that deals in metals.

If you are a production business or manufacturer in need of metal components or processed products, do not hesitate to consult with us at DOHO for your manufacturing needs in the area of non-ferrous metals.

Our Processed Products/Components Business, which constitutes one of our three business areas, assists customers with the manufacturing endeavors that they require from a global angle. Our true mission is to work together with our customers to bring forth the very best results and grow alongside each other as we move forward.

Increasingly-diverse lifestyles and innovations in technology have given way to daily evolutions in products in a variety of fields. The field of manufacturing underpinning those products is currently on the verge of a major transformation.

In order to devise ideas alongside our customers and make contributions to manufacturing, which will continue to become increasingly diversified going forward, we will start offering metal molding services centered on metal 3D printers.

We believe that molding technologies, the kind that only 3D printers and not cutting can provide, and manufacturing processes that are not solely dependent on veteran craftsmen will be indispensable in the forthcoming generation of manufacturing.

In addition to equipment, DOHO will provide a full gamut of 3D metal shaping services, from the supply of metal powder to after-sales maintenance, by fully utilizing the knowhow that we have cultivated in the materials field.

We are consistently attentive to the needs of our customers, and make it a policy to propose equipment that delivers high cost performance. In our minds, “proceeding to come up with ideas together” is the true nature of a partnership.

We will take on the challenge of a metal shaping business for the forthcoming generation through metal 3D printers. In addition to equipment, we at DOHO will provide the kind of comprehensive support that customers expect from us, covering everything from powder materials to processing.
