- Key Products/Technologies
- Heat Treatment Business: Possession of vacuum heat treatment, oxy nitriding, plasma nitriding, gas nitriding, PVD COATING, and vacuum carburizing technologies. Vacuum heat treatment offers improved toughness, strength, and hardness of components through changes in metal structure in a vacuum state, minimizing deformation during processing, ensuring excellent surface brightness, preventing oxidation and decarburization, and providing an environmentally friendly process. Its applications are extensive, including various forging dies, extrusion dies, semiconductor molds, automotive, and machine parts. Oxy nitriding is an eco-friendly process for enhanced corrosion resistance, achieving superior wear resistance, anti-seizure properties, increased surface hardness, and strengthened wear characteristics. Plasma nitriding is an environmentally friendly, pollution-free, and energy-saving process, preventing product deformation during low-temperature treatment and improving wear and fatigue properties. Gas nitriding involves nitrogen penetration into the steel surface and the formation of a hardened iron nitride layer by heating in an NH3 atmosphere at approximately 500°C, eliminating the need for quenching and enhancing the wear and fatigue properties of components. PVD COATING utilizes Physical Vapor Deposition technology to form ultra-hard thin films, simultaneously improving lubrication, wear resistance, and corrosion resistance, while minimizing changes in base material hardness and dimensions due to low processing temperatures. TiN coating is applied to various tools and cold dies. Vacuum carburizing is a carbon penetration technology in a vacuum, utilizing simulation programs based on material and requirement specifications, achieving over 50% faster carburization speed, absence of intergranular oxidation layer on the surface, excellent fatigue properties, beautiful surface appearance, minimized dimensional changes, and rapid processing. Applicable items include wear and fatigue-resistant dies such as hot/cold forging dies, deep drawing dies, upset dies, automotive parts (e.g., PINTLE), SUS types, titanium parts, injection screws, and cylinders.Heat Treatment Business: Possession of vacuum heat treatment, oxy nitriding, plasma nitriding, gas nitriding, PVD COATING, and vacuum carburizing technologies.
