Electroplating Surface Treatment
Overview of NPXingye Electroplating Services
In custom metal parts manufacturing, electroplating is one of the most mature and widely used surface treatment processes. NPXingye leverages decades of experience in precision metal parts production to integrate electroplating seamlessly with stamping, sheet metal fabrication, CNC machining, and forging processes. This enables us to deliver electroplating solutions that enhance corrosion resistance, functional performance, and aesthetic quality for our clients.
Electroplating works via an electrochemical reaction to deposit a uniform metal layer onto the surface of a metal substrate. This coating significantly improves corrosion resistance, wear resistance, conductivity, and assembly stability without compromising the original dimensional precision of the parts. The process is particularly suited for medium to large-volume custom parts, providing consistency while maintaining cost efficiency.
NPXingye’s electroplating services serve a wide range of industries, including:
Automotive manufacturing
Industrial equipment & automation
Electronics & electrical components

Materials:
Common Materials Suitable for Electroplating
Electroplating is not limited to a single material; XY can match different base materials according to part requirements:
Carbon steel / Alloy steel (most common, high rust resistance required)
Stainless steel (requires pre-treatment before plating)
Copper and copper alloys (for conductive or electronic parts)
Aluminum alloys (requires special pre-treatment or base layer)
Zinc-based materials
In practice, the suitability of electroplating is evaluated based on material properties, operating environment, and subsequent assembly requirements.
Electroplating Process & Steps
Electroplating is an electrochemical process involving multiple steps to ensure coating quality and uniformity. Nanpi Xingye strictly controls every step to achieve optimal results.
Pre-Treatment
Degreasing / Cleaning: Removes oil,grease, and surface contaminants to ensure strong adhesion of the plating layer.
Pickling: Removes surface oxides from the metal.
Activation Treatment: Uses chemical agents to enhance coating adhesion.
Electroplating Deposition
Plating Bath Setup: Adjusts chemical composition and pH of the electrolyte according to plating requirements.
Current Control: Controls current intensity and plating time to ensure uniform coating thickness.
Post-Treatment
Passivation & Sealing: Improves corrosion resistance of the plated metal.
Rinsing: Cleans plated parts with deionized water to remove residual chemicals.
Quality Inspection
Coating Thickness Measurement:Ensures the plating layer meets the specified thickness.
Adhesion Testing: Confirms that the plating layer adheres securely and does not peel.
