Business Activities

Three Essential Metal Processing Businesses for Manufacturing ■ Heat Treatment Business We restore the internal structure of metals that have become brittle after processing to their original state. > Vacuum Heat Treatment By performing heat treatment in a vacuum, we minimize dimensional changes and achieve a clean finish on the metal surface. □ Benefits Increased strength, increased hardness, stress relief, adjustment of magnetic properties, etc. > Brazing We join metals together using filler material. Simultaneous processing with heat treatment is possible. □ Benefits Joining of hollow parts, joining of dissimilar metals, etc. ■ Coating Business We generate a hard ceramic thin film on the metal surface, imparting high functionality. □ Benefits Wear resistance, sliding properties, durability, anti-adhesion, etc. ■ Thermal Spraying Business We spray molten material onto the metal surface to form a high-quality coating. □ Benefits Wear resistance, thermal insulation coating, high-temperature oxidation resistance, corrosion resistance, etc.
