Story 1 The Company's Roots

Created in 2004 from a merger of the copper tube divisions of Kobe Steel, Ltd. and Mitsubishi Materials Corporation.

KMCT was created in April 2004 from a merger of the copper tube divisions of Kobe Steel, Ltd. and Mitsubishi Materials Corporation to respond to the shrinking market in Japan and expanding market in Southeast Asia.

Our production base has been expanded unfolds in Thailand and Malaysia other than Japan.
The overseas factory works on the production capacity reinforcement sequentially and copes with the overseas market growing up.

In 2021, KMCT has strengthened its business competitiveness by acquiring a part of the Daishin P&T's copper tube business at its Amagasaki Plant and transferring it to KMCT's Hatano Plant, resulting in achieving further business growth.
We will continue to develop and produce new products to meet the needs of customers not only in Japan but worldwide.

Story 2 Products and Markets

Supporting a wide range of industries and society through development and supply of copper tubes for air-conditioning and other uses.

Copper offers superior thermal conductivity, corrosion resistance, antibacterial properties and workability. Copper tubes, which make the most of these advantages, is widely used in many areas affecting everyday life.

Air-conditioning is a prominent example. High performance inner-grooved copper tubes, one of KMCT’s chief products, can be used in indoor and outdoor air-conditioning units to achieve better heat exchange. Due to its exceptional ease-of-handling, copper tubes can also be used in the piping that connects the indoor and outdoor units.

In addition to air-conditioning, KMCT offers products for a wide variety of fields, including refrigeration, construction, hot-water supply and electronics. In order to meet society’s diverse needs we engage in development and production of a wide gamut of copper tubes.

Story 3 Sophisticated Materials Technology”

A pioneer in copper alloy tubes, pursuing new possibilities in the use of copper.

Utilizing sophisticated materials technology cultivated over many years, KMCT develops new copper tube products to meet markets needs as they change with the times.

For instance in recent years, with the increased concern for global warming, natural refrigerants such as carbon dioxide have begun to be used as coolant in heat pumps, vending machines and other devices in place of the CFCs, HFCs, and HCFCs previously used. Since natural refrigerants are highly pressurized when used, thick-walled copper tubes are required. However, thin-walled copper tubes are preferable from a cost perspective.

With cooperation between our R&D department and other research organizations, KMCT engages in continual research and development and has created a revolutionary high -strength copper alloy tube that achieves thinner walls while maintaining the exceptional workability inherent to copper. Because the copper alloy tube is stronger than conventional copper tubes, it requires sophisticated production technologies in many aspects. However, through the combined efforts of our R&D, manufacturing, quality control and machinery divisions, KMCT has been succeded in commercial production of it. Additionally, by offering a range of corrosion-resistant copper alloy tubes, we have increased the potencial availability and range of applications for piping.

KMCT will continue to be a pioneer in the world of copper alloy tubing, uncovering new possibilities for copper and leading the industry.

Story 4 Proprietary Processing Technology

Taking advantage of the years of experience and development behind our sophisticated processing technologies.

In 1979 the Hatano Plant, the crux of our production network, was the first plant in the world to successfully mass produce inner-grooved tubes. Sophisticated processing technologies such as these have remained a tradition at KMCT to the present day.

In recent years, with the increasing need for thin-wall and small–diameter copper tubes, the technological demands placed on manufacturing have grown increasingly complex. For instance, the decreased size and increased efficiency of air conditioners has led to smaller diameter and thinner walls for inner-grooved copper tubes.

From melting to packing, a range of technologies, knowledge and expertise are necessary during production, requiring us to make use of our many years of experience amassed in the industry. In order to further improve quality and productivity we will continue to engage in development of manufacturing and equipment technologies, providing better products to customers faster and at lower costs, and striving to always evolve with the times.

Story 5 Production and Supply Network

Meeting the increasing demands and needs of Asia, with plants in Japan, Thailand and Malaysia.

The global demand for copper tubes, including from developing nations, is on the rise. In order to respond to this trend KMCT expanded overseas at an early stage, bringing production and sales closer to newly growing markets.

Production in Japan is carried out entirely by the Hatano Plant. This plant can handle everything from melting to tube fabrication and treatments, with an annual production capacity of 60,000 tons. In addition to copper tube for air-conditioners, construction, electronics and other uses, the plant also produces semi-finished pipes supplied to the Malaysia Plant. The Hatano Plant is the only one of KMCT’s plants to boast its own Research and Development Department, and serves as the crux of our production network.

Like the Hatano Plant, the Thailand Plant is fully equipped and capable of all process from melting onwards. As the Group’s newest plant, it features state-of-the-art facilities, with an annual production capacity of 30,000 tons. The plant serves as a global center, exporting products not only to Asia, but also the Middle East, Europe and elsewhere.

The Malaysia Plant receives semi-finished goods from the Hatano and Thailand plants and uses them to manufacture copper tubes for air-conditioners and other applications. Its yearly production capacity is 10,000 tons. While the production capacity is lower than the other two plants, the plant specializes in products such as capillary tubes and fabricated parts.

Together, the Group’s annual production capacity is 100,000 tons, a leading figure among copper tube manufacturers worldwide. The Hatano and two overseas plants engage in active exchange of people, technologies and items, forming a well-oiled and perfectly optimized global production network. This allows us to produce high-quality products in the shortest amount of time possible.

Story 6 Vision and Strategy

To the second founding

The demand for air-conditioners is expected to increase, especially in developing nations exhibiting strong economic growth and developed nations where the rate of ownership is currently low. The number of air conditioners is expected to increase.

In addition, as part of the SDGs actions, it is anticipated that calls for the development of high value-added copper tubes, such as small diameter inner-grooved tubes, will increase to meet the growing need for further energy-saving and eco-friendly products.

In 2021, as announced in the press release titled “Announcement on Cancellation of Planned Share Transfer of Issued Shares” dated December 24, 2020, the Company has strengthened its business competitiveness by acquiring a part of the Daishin P&T’s copper tube business at its Amagasaki Plant and transferring it to KMCT’s Hatano Plant. In April 2022, we carried out a company name change to "KMCT" . We keep moving forward with copper tube, and we will continue to contribute to society with our cutting-edge development and technological capabilities, while revisiting the basics of manufacturing where we started.

Europe Strategy for European Markets The market for air-conditioners, especially high-end units, is expected to expand. We will use the Thailand and Malaysia plants to supply high-quality and high-performance copper tubes. Asia Strategy for Asian Markets The market in Asia for mid-range and economy air-conditioners is expanding. In order to meet this growing demand we will continue to supply high-quality and high-performance copper tubes from the Hatano, Thailand and Malaysia plants.
