Low-reflective black plating is a surface treatment technology that significantly suppresses light reflection through a special fine surface structure (moth-eye structure), reducing the occurrence of flare and ghosting. It accommodates a wide range of wavelengths from ultraviolet to visible to infrared, contributing to stray light prevention and resolution enhancement in optical devices and cameras. It achieves a specular reflectance of less than 0.1% and a total reflectance of less than 5%, demonstrating excellent low-reflective performance. It can be applied to various metals such as aluminum, copper, iron, and stainless steel, and is compatible with complex shapes. Furthermore, it is an environmentally friendly plating technology that complies with RoHS2. The selection of surface shapes is also possible according to the required performance.

This product is a surface treatment technology that enables silver plating on iron materials through a unique technology, providing an alternative to traditional copper electrical contacts. Since conductivity, which is crucial for electrical contacts, is dominated by the silver-plated surface, the contact performance can be maintained even when changing the base material from copper to iron. Furthermore, a two-layer plating structure is adopted to prevent galvanic corrosion (dissimilar metal contact corrosion), ensuring high corrosion resistance. Additionally, by establishing a rapid washing, draining, and drying process, high-quality silver plating on iron materials, which was previously difficult, has been achieved. This significantly reduces material costs, allowing for a reduction of over 90%.

This is a plating technology that leverages the lightweight and molding flexibility of resin while providing high electromagnetic wave shielding performance. By using copper (Cu) or nickel (Ni) plating, it reflects electromagnetic waves and achieves a shielding effect of over 99.99% (over 80dB). It accommodates a wide frequency range from low to high frequencies and can effectively block both electric and magnetic fields. It has excellent adhesion, eliminating concerns about peeling like a film, and also boasts long-term reliability. Two types are available based on application: single-sided plating and double-sided plating, contributing to designs that do not require shielding housings. Depending on the application, you can choose between single-sided and double-sided plating.

This is a surface treatment technology that applies a high-density and thick metal plating to fiber-reinforced plastics such as CFRP (carbon fiber reinforced plastic) and GFRP (glass fiber reinforced plastic), imparting new functions while maintaining the conventional lightweight properties. Our unique process enables the formation of pinhole-free coatings, preventing outgassing and allowing for compatibility with vacuum environments. Additionally, it simultaneously achieves multifunctionality by providing conductivity, electromagnetic wave shielding, and improvements in surface hardness, impact resistance, and weather resistance. We can also accommodate large items (with a dedicated plating line for large FRP) and propose optimal plating specifications tailored to various applications. This technology expands the performance of FRP and contributes to high added value across a wide range of industrial fields. *For more details, please refer to the PDF document or feel free to contact us.*

Electropolishing is widely used as a finishing process for stainless steel not only because of its excellent luster but also because it improves corrosion resistance after electropolishing. By electropolishing, the altered layer and temper scale caused by prior machining are removed, along with contaminants on the surface (such as debris and dirt from processing), resulting in a cleaned surface. Additionally, through electropolishing (anodic dissolution), a thin oxide film is formed on the surface, creating a passive film. This passive film has a higher chromium content than the base material (the stainless steel substrate), resulting in a coating with good corrosion resistance. Furthermore, by eliminating surface roughness, it becomes more difficult for debris and dirt to adhere to the surface after electropolishing, which also contributes to improved corrosion resistance.
