The Aluminum Housing Nickel-Gold Plating Equipment is a complete system specifically designed for functional electroplating on aluminum alloy housing surfaces. Its core process addresses the challenge of coating adhesion caused by the inherent reactivity and easy oxidation of aluminum materials.

The equipment typically follows a standardized automated process: It begins with specialized pre-treatments such as electrolytic degreasing and activation to thoroughly remove the oxide layer from the aluminum surface and form an activated layer. This is followed by electroless or electroplating of a dense nickel layer, which serves as an intermediate barrier and base layer, providing primary thickness, hardness, wear resistance, and corrosion resistance. Finally, a thin gold layer is electroplated onto the nickel layer, leveraging gold's excellent conductivity, oxidation resistance, and solderability to achieve the desired surface functionality.

Application Fields

This equipment is widely used in industries requiring specific electrical, physical, and aesthetic properties for electronic device housings:

• Core Applications:

• Aerospace & Military Electronics: Provides excellent electromagnetic shielding, environmental corrosion resistance, and long-term reliability for chassis and shielding cases.

• High-End Communication Equipment: Ensures low-resistance connections and signal integrity for components such as 5G base station filters, waveguide cavities, and RF module housings.

• Precision Medical Devices: Meets requirements for biocompatibility, surface cleanliness, and resistance to chemical sterilization in medical equipment housings.

• Typical Scenarios:

• Equipment housings requiring reliable grounding and electrical conductivity.

• Cavities for high-frequency signal transmission or electromagnetic shielding.

• Consumer electronics or industrial product housings that demand corrosion resistance, wear resistance, and premium appearance.

By applying the nickel-gold composite coating, this equipment perfectly combines the lightweight and cost-effective advantages of aluminum with surface multifunctionality, making it a key technological asset for enhancing product value.
