Process Overview
Chrome Plating
Chrome plating is one of the most recognisable and technically demanding electroplating processes. It deposits a thin layer of chromium onto a substrate, creating a mirror-bright, highly corrosion-resistant surface. At Sunsai, we offer both decorative chrome (for aesthetics) and hard chrome (for industrial wear resistance).
Coating Thickness
0.1–0.5 µm (decorative) | 25–500+ µm (hard chrome)
Typical Turnaround
3–5 business days (standard)
Available Types
Types of Chrome Plating
Decorative Chrome
Thin, bright finish applied over a nickel undercoat. Used for automotive trim, furniture hardware, bathroom fixtures, and consumer products. Provides a high-gloss mirror appearance with good corrosion resistance.
Hard Chrome
Thick industrial chrome deposit (25–500+ microns) applied directly for wear and corrosion resistance. Used on hydraulic cylinders, shafts, moulds, and machine components. Exceptional hardness (900–1100 HV).
Industrial Chrome
A versatile chrome deposit for engineering applications requiring a combination of wear resistance and corrosion protection with dimensional restoration capability.
Why It Works
Key Advantages
- Exceptional hardness and wear resistance
- Outstanding corrosion protection
