Supporting next-generation technology
with an enhanced production system

With the advancement of vehicle electrification and the dissemination of the 5G communication system, there is a growing demand for processed copper products, such as automotive terminals and electronic parts for heat dissipation.

To contribute to the development of technologies for the next generation, Mitsubishi Materials has set forth the goal of enhancing the supply of high-performance materials and products in the FY2031 Strategy. The Copper & Copper Alloy business is making efforts to strengthen the system for producing copper billets and cakes, which are raw materials for the processed copper products.

Strengthening the production system

The Sakai Plant, our mainstay manufacturing site for copper billets and cakes, has been enhancing its casting facilities with the goal of increasing production volume from its current state. However, simply enhancing facilities is not enough to achieve this goal. To achieve a system for increased production, it is necessary to analyze and improve four elements: plant employees, machines, materials, and methods. Collaboration with other plants and divisions is also essential. This is because the production system can be strengthened by aligning production with the sales department and the Sambo Plant, which handles secondary processing, and by aiming to optimize operations and inventories.

Therefore, looking ahead to facility enhancement, the Sakai Plant has been working on increasing the operating rate of existing lines for a few years, while enhancing collaboration with the Sambo Plant and other relevant organizations by having close discussions and sharing operational procedures. This has improved the operating rates of existing lines and established a system that maximizes the abilities of each site.

Considering the utilization of digital transformation (DX) to build a more efficient production system, the plant will further expand its production volume.
