4.Thickness: Typical coating thickness is 5–25 μm with minimal dimensional impact.
5.Advantage: Maintains tight tolerances while improving surface performance.
6.Capability: Suitable for steel, metal, and industrial components.
7.Quality: Inspection covers coating thickness, adhesion, and surface uniformity.
CNC Machining Electroplated Parts
Our CNC Machining Electroplated Parts have a solid surface finish and are machined to very tight tolerances. We offer unique solutions from prototype to mass production. Our factory team has more than 9 years of experience and the engineers have an average of 15 years of experience. Our unified process makes sure that the measurements are accurate to within ±0.02 mm while adding even plating layers of 5–25 μm. Sample production usually takes 7 days, but for easier shapes, fast service is possible in 3 days. Nickel, zinc, and chrome coating can be done on steel, aluminium, brass, and stainless steel parts.
What Are CNC Machining Electroplated Parts?
These are precisely made metal parts that have been given a protective metal layer by electroplating.
The first step is CNC cutting or turning to make exactly what you want. Parts are cleaned and activated after being machined before going into the coating bath.
A thin layer of metal that is all the same thickness sticks to the surface. This covering makes the part more resistant to rust and makes it last longer.
With this one option, you get both accurate measurements and security for the surface.
Our Electroplating Process
Step 1: Precision
Machining We use high-tech CNC machines to make your parts. Before coating, complicated shapes and close standards are made.
Step 2: Surface
Preparation All of the parts are cleaned and turned on. This makes sure that the layer sticks well.
Step 3: Electroplating Application
Through an electrical process, metal ions stick to the surface. The coating builds up evenly on all the places that are visible.
Step 4: Quality Verification
We check the amount of the covering, how well it sticks, and how even the surface is. Before it is shipped, each batch has to meet certain standards.
Available Plating Options
Nickel Plating
Ideal when you need to make something harder and more resistant to wear. CNC Machining Electroplated Parts has a bright, long-lasting finish that protects well against rust.
Zinc Plating
A cheap way to protect steel parts from rust. Often used in industrial and automobile settings.
Chrome Plating
Provides extreme sharpness and a mirror-like finish. It can be used for both decoration and functionality.
Because each application is different and needs different levels of performance, we help you choose the right finish.

Why Choose Our Electroplated Parts?
Dimensional Stability
Electroplating doesn't make your part bigger like thick coats do—it only adds 5–25 μm. This small effect keeps your key limits the same.
Engineering Support
Your drawings are looked over directly by our experts. Before production begins, we give you advice on how to choose the right material, finishing type, and design optimisation.
Fast Turnaround
We keep contact open and work well together from the price to the delivery. Any problems with quality are fixed by remanufacturing within a week, and the shipping costs are paid.
Flexible Production
We can meet your bulk needs, whether you need 10 samples or 10,000 production parts. Your project isn't limited by minimum order requirements.
Complete Traceability
On request, we can give you material certificates and plating thickness records. The results of the salt spray test show how well the rust resistance worked.
Common Applications
Your electroplated CNC parts can serve in:
- Automotive fasteners and brackets
- Industrial machinery components
- Electronic hardware and connectors
- Medical device housings (FDA-compliant materials available)
- Aerospace structural elements
- Food processing equipment
The combination of precision machining and protective plating suits both functional and decorative requirements.
Quality Assurance
Pre-Plating Inspection
Machined parts are verified for dimensional accuracy and surface condition. Any defects are corrected before plating begins.
Coating Control
Plating parameters are monitored throughout the process. Thickness gauges confirm uniform coverage across complex geometries.
Final Verification
Adhesion tests, thickness measurements, and visual inspections ensure every part meets specifications. We follow international standards for surface treatment quality.
FAQ
Q: What is electroplating for CNC machined parts?
Nickel or zinc electroplating improves corrosion resistance, conductivity, and appearance on CNC machined objects.
