ED Coating

FNX ED E-Coating – Corrosion-Resistant E-Coating Solution for Automotive Components and Metal Parts is a solution in the field of electrophoretic coating / E-coating / electrodeposition coating / metal surface treatment / anti-corrosion coating / phosphating, connected and provided by FNX Supply Chain Company Limited (FNX-SC) through its network of surface treatment enterprises within the FNX ecosystem, serving automotive and motorcycle manufacturers, Tier 1 – Tier 2 enterprises, precision mechanics, electrical – electronics, industrial equipment, and metal parts manufacturers.
The solution is used to create a protective coating on metal surfaces using the electrophoretic method, supporting corrosion resistance, creating a relatively uniform coating, and preparing the surface for subsequent finishing processes.
Within the FNX network, MSTS Seikou Tousou is a capable ED coating provider with a process including degreasing – rinsing – activation – phosphating – ED coating – UF rinsing – drying.
ED coating technology uses an electric field to facilitate paint deposition onto the surface of conductive materials, suitable for brackets, stamped parts, metal frames, steel components, automotive – motorcycle parts, and products with relatively complex shapes.
Depending on the project, the treatment plan can be developed based on substrate material, part dimensions, shape, corrosion resistance requirements, color, coating thickness, production volume, and technical standards.
FNX-SC acts as the supply chain focal point, supporting request reception, connecting suitable processing units, and coordinating implementation within the surface treatment network.
