Metallic Coating Service
Metallic coatings are a variety of metal-based or alloy-based coatings applied through different processes over metal part surfaces. Some of the common methods are applying the coat using spraying, electrochemically, chemically, or mechanically.
Metallic coating for metals doesn’t require much preparation since metals are good conductors. For materials that are poor conductors of electricity, the surface needs to be prepared first. This can be done through electroless plating or other chemical preparation processes.
The metallic coating gives a metallic shine and glossy finish to any surface it is applied on. The finish is also corrosion, sunlight and oxidation-resistant.

Die Cast Industry: Status in 2026 and Trends by Segments
Die-casting is a process of creating metal components by forcing molten material into a reusable mold (called a die), where it fills the cavity and takes the shape upon solidification.

Choose the coating system from the substrate and failure mode
Metallic coatings should be selected by the failure mode to be controlled: corrosion, wear, conductivity, solderability, appearance or dimensional build-up. Define the substrate, preparation, coating sequence, thickness, protected geometry and verification method.
Engineering data to lock before release
| Failure mode | Corrosion, wear, contact, solderability or appearance |
|---|---|
| System stack | Base material, underlayer, top layer and treatment |
| Dimensional data | Coating build-up at fits and threads |
| Verification | Thickness, adhesion, corrosion or electrical test |
Coating chemistry and thickness alone are not enough; the preparation and measurement plan also need to be controlled.
