```What Is Electroplating?
Electroplating is a metal surface finishing process that deposits a thin layer of metal onto the surface of a part through an electrochemical reaction. The plated layer can improve corrosion resistance, wear resistance, electrical conductivity, solderability, hardness and appearance, depending on the plating material and application requirements.
Electroplating is widely used for CNC machined parts, sheet metal parts, stamped parts, fasteners, connectors, housings, brackets, shafts and precision mechanical components. Common plating types include nickel plating, zinc plating, chrome plating, copper plating and tin plating.
For custom metal parts, electroplating is not only about making the surface shiny, because apparently manufacturing refuses to be that simple. The correct plating process must consider base material, coating thickness, surface roughness, masking areas, threaded holes, contact surfaces and the final working environment.

Electroplating Services
We provide different electroplating solutions based on material type, part function, surface performance, appearance requirements and production volume. Choosing the correct plating process matters because one wrong finish can turn a beautiful machined part into an expensive paperweight. Humanity has built rockets, yet still forgets to mark threaded holes on drawings. Tragic, but preventable.
Nickel Plating
Nickel plating provides good corrosion resistance, wear resistance and a clean metallic appearance. It is commonly used for mechanical parts, housings, connectors, shafts and precision components.
Zinc Plating
Zinc plating is widely used for steel parts that require corrosion protection. It is suitable for brackets, fasteners, hardware parts, sheet metal components and industrial equipment parts.
Cromado
Chrome plating provides a bright appearance, surface hardness and wear resistance. It is often used for decorative parts, mechanical components and products requiring a durable metallic finish.
Copper Plating
Copper plating is often used as an intermediate layer or functional coating to improve conductivity, adhesion and surface preparation for further finishing.
How Our Electroplating Process Works
Our electroplating process follows a controlled workflow from drawing review to machining, surface preparation, cleaning, plating, post-treatment, inspection and packaging for custom metal parts.
-
Drawing and Requirement Review
We review material grade, plating type, coating thickness, appearance requirements, masking areas, threads, holes, tolerances and assembly conditions.
-
Machining and Surface Preparation
The metal parts are machined, deburred and cleaned. Surface preparation may include polishing, brushing, sandblasting or degreasing depending on the required finish.
-
Cleaning and Activation
Parts are cleaned and chemically activated to remove oil, oxidation and contamination before the plating process.
-
Electroplating Treatment
A controlled electrochemical process deposits the selected metal coating onto the part surface according to the required plating type and thickness.
-
Post-Treatment
Depending on the plating type, parts may go through rinsing, passivation, sealing, drying or other post-treatment processes.
-
Inspection and Packaging
We inspect coating appearance, surface defects, adhesion, critical dimensions, threaded areas and batch consistency before protective packaging.
Process note: For electroplated parts, drawings should clearly mark threads, precision holes, contact surfaces, sealing areas and any areas that must not be plated. If those details appear only after production, congratulations, the project has entered the ancient art of avoidable rework.
```Machining and Surface Finishing Support
In addition to electroplating, we also provide CNC machining and surface preparation support for custom metal parts. This helps customers manage quality from raw material to finished surface, instead of juggling five suppliers and pretending that chaos is a workflow.

DFM Support
We evaluate how electroplating may affect coating thickness, tolerances, masking, assembly and final part performance.
Preguntas frecuentes
Common questions about electroplating, plated metal parts and surface finishing requirements.
What is electroplating used for?
Electroplating is used to improve corrosion resistance, wear resistance, surface hardness, conductivity, solderability and appearance. It is commonly applied to CNC machined parts, sheet metal components, stamped parts, fasteners, connectors and industrial hardware.
What materials can be electroplated?
Common materials include steel, stainless steel, brass, copper, aluminum, zinc alloy and other metal materials. The exact process depends on the base material and plating requirement.
What types of electroplating do you offer?
We support nickel plating, zinc plating, chrome plating, copper plating, tin plating and other custom plating options based on part function, appearance and working environment.
Does electroplating affect part dimensions?
Yes. Electroplating adds a metal layer to the part surface, so coating thickness may affect holes, threads, slots, mating surfaces and tight-tolerance areas. Critical dimensions should be clearly marked on the drawing.
Can aluminum parts be electroplated?
Yes, aluminum parts can be electroplated, but they usually require special pre-treatment because aluminum naturally forms an oxide layer. The plating process should be confirmed according to the aluminum grade and final application.
What is the difference between nickel plating and zinc plating?
Nickel plating is often used for wear resistance, corrosion resistance and decorative appearance. Zinc plating is commonly used for corrosion protection on steel parts, especially fasteners, brackets and industrial hardware.
Can electroplating be used for electrical components?
Yes. Copper plating, tin plating and nickel plating are often used for conductive parts, terminals, connectors and electrical components that require conductivity, solderability or contact performance.
What information is needed for an electroplating quotation?
Please provide 3D CAD files, 2D drawings, material grade, quantity, plating type, coating thickness requirement, surface appearance requirement, critical dimensions and any masking areas.
Can you provide machining and electroplating together?
Yes. We can support CNC machining, sheet metal fabrication, stamping, deburring, polishing, cleaning, electroplating and inspection as an integrated manufacturing solution.
Do you support prototype and low-volume electroplated parts?
Yes. We support prototype, low-volume and production electroplated metal parts. For appearance-critical or performance-critical parts, sample confirmation is recommended before batch production.
