The German RAMPF Group and its Japanese subsidiary RAMPF Group Japan Co., Ltd., along with Hinode Water Supply Equipment Co., Ltd., have signed a business partnership agreement to jointly develop, produce, and sell mineral casting products, leveraging their respective technological expertise for mutual growth. Mineral casting is a type of polymer concrete made by solidifying resin and aggregates. It uses ores of varying particle sizes as aggregates, bonded with epoxy resin, and is a high-performance composite material widely used in industrial machinery applications in Europe and other regions, where high precision and high-speed operation are required.

Hinode Holdings Co., Ltd. and Hinode Water Supply Equipment Co., Ltd. have jointly developed the high-strength aluminum casting alloy "ATHIUM" in collaboration with Makino Milling Machine Co., Ltd. (Headquarters: Meguro, Tokyo) and Tajima Light Metal Co., Ltd. (Hanyu City, Saitama Prefecture).
