Finishing Options for Machined Parts

Adding a finish to machined parts and enclosures is not solely about aesthetics; it also enhances protection and performance attributes.

In this blog, we will walk through the options for bare metal, anodized, and powdercoat finishes, so you can find the perfect fit for your project.

Why Add Finishing for Machined Parts?

A good protective finish can add layers of defense, ensuring longevity and performance under stress.

Secondly, finishing serves aesthetic and communication purposes. An aesthetically-pleasing finished part not only looks professional but can also communicate the identity of your brand as well as mention instructions or labelling connectors on your part.

Therefore, you should carefully consider finishing options during the design process.

Now, let’s take a look at the options that we offer at Evernice

Bare Metal Finish or No Finish

Our most popular finishing options for machined parts are bare metal finishes or no finish, also called a stock finish.

For machined parts, no finish refers to the appearance straight off the machine, with visible toolpath patterns from the CNC mill or lathe tooling. These parts may also have minor surface scratches.

Design Considerations for Bare Metal Machined Parts

When applying a grained finish to milled parts, only the exterior surfaces can typically be brushed. Part geometry is important, especially if your part lacks easy-to-reach flat surfaces for brushing.

Anodizing

Anodizing is an electrochemical process that enhances the metal’s natural oxide surface, providing increased corrosion resistance and a decorative finish.

If your project involves parts exposed to heat or electricity, an anodized finish ensures corrosion resistance. With its hard surface, especially when using Type III anodizing, it adds a durable layer that extends the lifespan of parts and protects against scratches and wear.

Powdercoat

Powdercoating involves electrostatically applying a dry, free-flowing powder to a part, which is then cured in an oven to create a hard, durable finish.

Part Logo and Graphics

We also offer permanent part logo options such as laser engraving and UV Printing.

We can add graphics to your machined parts via laser engraving and UV Printing if required too. Adding graphics is a great way to communicate your brand or to add label cutouts for connectors and electronics.

Conclusion

Finishing your machined part is a balance between what looks good, what feels right, and what works well.

Understanding design considerations and the benefits of each type of finish will help you make the right decisions. This will result in machined parts and enclosures that are not only structurally sound but are also visually appealing, durable and meet your specific requirements.
