If you're looking for a guide to plating options for CNC machined parts, then you've come to the right place.

Plating is an important part of machining since it can make all the difference when it comes to quality and durability.

It's essential to understand the different types of plating available so that you can choose the best option for your project.

We're here to help!

We'll provide an overview of the various plating options, from galvanized to chrome plating, and explain what each type is used for.

By understanding the different plating options available, you'll be able to make an informed decision when it comes time to decide on what type of plating works best for your CNC machined parts.

You'll also feel confident knowing that you've made the right choice for your project!

Galvanized Plating

Galvanized plating is like a coat of armor for your CNC machined parts. It provides a durable, protective layer that secures your parts against corrosion and environmental hazards.

This process involves dipping the parts in a specially-designed bath of molten zinc alloy to ensure the coating adheres to the surface.

The anodizing process ensures the galvanized plating will not be easily scratched or damaged by everyday use.

Additionally, this method produces an aesthetically pleasing finish without compromising on durability.

This makes it the perfect choice for CNC machined parts that require additional protection from the elements. With this method, you can rest assured your parts will stay looking great and remain functional for years to come.

Zinc Plating

Zinc Plating

Moving on from galvanized plating, let's explore zinc plating.

Zinc plating is an affordable and efficient way to protect metal surfaces from corrosion and abrasion. It also provides a reliable base for paint adhesion, which makes it a great choice for CNC machined parts. Moreover, zinc offers superior protection against rust because of its strong corrosion resistance properties.

Not to mention, the layer of zinc that is applied during the process can help create a smooth finish that will look aesthetically pleasing in any setting.

When looking at zinc plating as an option for your CNC machined parts, one of the key factors to consider is its ability to provide a durable layer of protection against corrosion. Zinc has been proven to be effective in preventing rust and other forms of corrosion due to its high adhesion strength and ability to form an effective barrier between the metal surface and the environment. Additionally, it can offer superior protection against wear and tear since it is highly resistant to abrasion.

All in all, zinc plating is an economical solution for CNC machined parts that need robust protection without compromising on aesthetics or quality.

Nickel Plating

Back in the day when electroless nickel plating was first discovered, no one could have imagined the diverse uses it would have today.

This coating process is still widely used as a decorative, corrosion-resistant coating to increase durability and aesthetic value of CNC machined parts.

Electroless nickel plating offers excellent wear resistance and friction control compared to anodized coatings.

It also provides good electrical conductivity, making it ideal for electronic contact surfaces.

Another great benefit of this type of plating is that it is non-magnetic — perfect for medical devices or other precision instruments where magnetic interference must be avoided.

Additionally, this coating has superior adhesion properties that make it resistant to chipping and flaking even when exposed to harsh elements.

In short, electroless nickel plating can provide both functional and aesthetic benefits for CNC machined parts.

Chrome Plating

Chrome Plating

Moving on from nickel plating, let's take a look at chrome plating.

It's a popular choice for CNC machined parts due to its excellent abrasion and corrosion resistance.

Chrome plating is a harder surface than nickel, making it ideal for hardness testing.

As an added bonus, it provides excellent environmental protection against wear, salt spray and other harsh conditions.

Chrome plating has high aesthetic appeal and can be applied in various thicknesses depending on the application and needs of the part.

It's also easy to maintain as long as it's cared for properly.

With regular cleaning and polishing, your cnc machined part will stay looking great for years to come!

So if you're looking for a reliable finish that is both strong and stylish, chrome plating is the way to go.

Tin Plating

Hey there! If you’re looking for a plating option for your CNC machined parts, you may have come across tin plating.

Well, tin plating is one of the most popular finishes out there, and it comes with some great benefits. First off, it's an affordable choice. Tin plating is usually less expensive than other metal finishing options like silver or gold plating. It also offers excellent corrosion protection against salt water and other corrosive elements. Plus, it produces a nice finish that has a shiny silver color.

But what else should you know about tin plating? Here’s a breakdown of the most important points:

  • Alloying: Tin plated parts are often alloyed with other metals like copper or nickel to make them stronger and more durable. This process can also increase their resistance to corrosion.
  • Durability: Tin-plated parts are incredibly strong and resilient due to their alloying process and can last for years without suffering from wear or tear.
  • Corrosion Resistance: The alloying process gives tin-plated parts excellent corrosion resistance in even the harshest environments.

So if you’re looking for an affordable and reliable way to protect your CNC machined parts, tin plating is definitely worth considering!

Powder Coating

Powder Coating

Next up in our guide to plating options for CNC machined parts is powder coating. It's an excellent choice if you want a durable finish that won't wear off easily.

This process involves applying a colored powder to the metal, then using heat to make it bond with the surface and create a protective layer. Unlike anodizing and electroplating, it does not require any chemical baths or other processes - just heating the powder.

The advantages of powder coating over other plating processes are clear: it's easy to apply and requires less maintenance over time. Plus, it's available in a wide range of colors, so you can match your part's finish to your exact needs.

It may not be as shiny as some of the other options, but its durability more than makes up for that. So if you're looking for something that'll last and look great for years to come, powder coating might be your best bet.


Finishing the look of your CNC machined parts is an important part of making sure your project looks polished and professional. Plating options can provide a layer of protection and make your parts look great.

Galvanized plating, zinc plating, nickel plating, chrome plating, tin plating or powder coating are all viable options when deciding how to finish off your CNC machined parts. Each has its own advantages and disadvantages so it's important to consider which option best suits your needs before making a decision.

No matter what you decide, you'll be sure to have a project that looks great and will stand the test of time.
