At Nikken Ras Kogyo, we manufacture high-quality power supply materials and electrode substrates in the hydrogen and fuel cell fields. As solid polymer-type water electrolysis devices and alkaline water electrolysis devices in the hydrogen and fuel cell fields are expected to become larger and mass-produced in the future, the power supply materials (titanium ras) and electrode substrates (nickel ras) incorporated in them will also increase in size. Our company has introduced a leveling device as a secondary processing step after ras processing, achieving higher product quality and improved productivity. 【Features】 ■ Introduction of leveling device ■ Capable of processing high-quality ras products with excellent flatness *For more details, please refer to the PDF document or feel free to contact us.

Our company offers a cleaning process using electrolyzed ionized water to enhance the surface treatment performance of electrode substrates and other materials. We possess "electrolyzed ionized water cleaning," which effectively removes oil stains through high-temperature cleaning. The electrolyzed ionized water generated by our specialized electrolysis equipment has surfactant effects and exhibits high cleaning power. Additionally, the surface tension of electrolyzed ionized water at room temperature (20°C) is equivalent to that of tap water at boiling point (80°C). Furthermore, it is often heated to around 50°C for cleaning, adding thermal energy and allowing for a more penetrating and powerful degreasing cleaning process for electrode substrates. 【Features】 ■ Effectively removes oil stains through high-temperature cleaning ■ Generates electrolyzed ionized water from regular water for use as a cleaning solution ■ Contains no cleaning chemicals, has high oil-water separation properties, and can be reused *For more details, please refer to the PDF document or feel free to contact us.
