We engage in the manufacturing and sales of various rolls, including cast-iron and semi-steel rolls, as a comprehensive roll maker with a focus on rolls for hot rolling, boasting the top market share of rolls made with special steel materials. We supplement both our static and centrifugal casting processes with special proprietary heat treatment techniques of our own.

Following in the footsteps of Shin Nippon Chain & Machinery Co., Ltd., a company that was Japan’s oldest chain manufacturer, our chain-manufacturing work is now operated as a Himatex business. With a record of orders for nationally contracted work since the early days of establishment in 1928, we take great responsibility and pride in our work. Over the course of our history, we have repeatedly worked to provide quality improvements and technological innovations to meet our customers’ needs.
Today, we continue to refine our technical capabilities as Japan’s sole manufacturer of forged chains.

We apply techniques including hot isostatic pressing and sintering to give powder metallurgy products enhanced performance offering wear resistance, corrosion resistance, non-toxic properties, and more. We also apply coatings to special materials we blend in-house to bestow special characteristics not subject to delamination or material loss more effectively than with ordinary thermal spraying.
