Continuous casting mold/Mold

Developed Ni electroforming as a first company in Japan and succeeded in its practical application.
As a top manufacturer, we are promoting export and technology licensing from our domestic bases to overseas.

In 1968, we started Cr plating on the inner surface of billet molds at the Yawata Works of Nippon Steel Corporation (currently Nippon Steel Corporation Kyushu Steel works Yawata), and in 1971, we developed and successfully put into practical use Ni electroforming (thick plating), the first such process in Japan.

Since then, for more than 50 years, we have been designing, manufacturing, and maintaining molds, which are the heart of the continuous casting process, as well as peripheral equipment as the industry's top manufacturer. In recent years,
we have applied the technology we have cultivated over many years to enter the production of high-precision molds for automobile-related equipment.

Achieving longer mold life and higher quality slabs

Along with remarkable progress in operating technology, the life of molds has increased dramatically, and the functions required for surface treatment have diversified.
Mishima's original (patented) mold that we developed, based on the highest level of manufacturing technology, continue to meet the needs of our customers by contributing to quality improvement and cost reduction through life extension in the steel industry.

Number of patents related to continuous casting (as of March 2021) 65
