basic information
■ Glossy and matte (pearlescent) finishes are available. ■ Hardness: 450-500 Hv (HRC 45-49) ■ Weather resistance: No discoloration after 200 hours of xenon irradiation Test equipment: Xenon weather meter X75H Test conditions: Dry at 63℃ * Xenon light has wavelengths close to sunlight, allowing observation of fading under normal environmental conditions. ■ Reflectivity - For incident wavelengths in the visible light range (350nm to 800nm), specular reflection is below 0.1. - Total reflection, including diffuse scattered light, is 4-6%, which is equivalent to or better than black chrome, known for its good heat absorption. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝= For other functions and details, please contact us.

Company information
In 1955 (Showa 30), we separated and became independent from a machinery factory (now Sanei Seiki Kogyo Co., Ltd.), and since then, we have been dedicated solely to plating processing, continuously providing various surface treatments that delight our customers. We have received high praise as a plating company that understands the needs and feelings of our customers, who are machinery manufacturers. We have obtained ISO 9001 and 14001 certifications and have been recognized for green procurement, conducting business activities that consider both quality and the environment. Currently, we specialize in electroless nickel plating and electrolytic polishing of stainless steel, and particularly for electroless nickel plating, we offer a variety of options tailored to different applications and needs. Additionally, we excel in small-batch, diverse production, so we can accommodate orders starting from just one piece. We also accept prototype and sample requests. We are committed to conducting research that lives up to our name as a research institute, aiming to assist with any challenges or the development of new products, so please feel free to consult with us. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ We provide high quality, low prices, and short delivery times. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
