A black electroless plating technology that can handle complex shapes and is resistant to scratches!
This is a black plating technology conducted using a non-electrolytic plating method. It provides a deep black coating with a piano black finish. No environmentally regulated substances are used (RoHS compliant). **Features:** - The coating thickness is uniform and can be applied evenly to complex-shaped parts and the inner surfaces of pipes. - Superior wear resistance compared to other black surface treatments. - High hardness, making it resistant to scratches (around Hv500). - Excellent heat resistance and light resistance (no discoloration due to UV exposure). - Average reflectance in the visible light range (including all diffuse reflection) is less than 10%. - Conductive coating, preventing static electricity buildup. - No environmentally regulated substances are used (RoHS compliant). **Properties:** - **Light Absorption:** Absorbs over 90% of light in the visible spectrum (380-750nm) on average. - **Corrosion Resistance:** No corrosion observed even after 150 hours of continuous exposure in a 5% salt spray test. - **Heat Resistance:** Reflectance does not change even after holding at 200°C for 2 hours. - **Precision:** Uniform film formation is possible for all shapes (±10% of specified thickness). - **Materials:** Treatment is possible for various materials. Please consult for details. *For more information, please download the PDF or feel free to contact us.*

Company information
Asahi Precision Co., Ltd. has a purchasing department primarily focused on the processing of precision equipment parts (from ordering parts and materials to processing and assembly) and a surface treatment department that performs plating. In the surface treatment department, we are committed to improving our technical capabilities without compromise, and in recent years, we have received awards such as the Kansai Monozukuri Shin-sen 2017, 2018, and the Kyoto Small and Medium Enterprises Technology Excellence Award 2018. To meet various needs, we are continuously working on the development of original plating technologies that are not available from other companies, and we currently offer over 15 types of special surface treatments. We leverage our unique "technical capabilities" and "know-how" as strengths, and we have established a production system primarily based on plating technicians. Furthermore, we have obtained ISO 14001 certification and are advancing environmentally conscious technology development as part of our management system.
