Bare-Metal Finishes
Protocase offers several bare finishes for custom parts, enclosures and panels.
No Finish: CNC Sheet Metal
![No Finish No Finish](img/no_finish/main.jpg)
- Part is de-burred with no additional finishing
- No added cost
- Best economics for functional parts that will not be on display
- This is not 'decorative' in anyway
- Minor surface scratches, swirl marks and blemishes are to be expected
- Surface can be digitally printed and silkscreened, although it is not advisable due to the fact that No Finish is not a decorative or aesthetically appealing finish
- CNC machined parts will have visible toolmarks
Grained Finish: CNC Sheet Metal
![Grained Finish Panel with Digital Print](img/grained_finish/Main_Image_Grained_Finish_Panel_with_Digital_Print.jpg)
- Part is de-burred, and then given a specific linear grain direction via brushing
- Applied to sheet metal parts before bending
- Can only be applied to accessible flat exterior faces on machined parts
- Aesthetically superior option for bare finish for parts or enclosures that will be displayed
- Can be digitally printed and silkscreened
Vibratory Finish: CNC Sheet Metal

- Smooths and imparts random finish via tumbling in abrasive medium
- Excellent for machined parts
- Great option for a random (non-directional) bare metal finish
- Maximum part size is 10"L x 10"W x 10"H
- Minimum part size - part must have a cross-sectional dimension of at least 1" (25.4 mm), and a length of at least 3" (76.2 mm)
- Rolls over corners very well
- Minimizes toolmarks on CNC machined parts
- Not available for copper
- Can be digitally printed and silkscreened

Media Blasting: CNC Sheet Metal
![Media Blasting Media Blasting](img/media_blasting/media_blasting.jpg)
- Part is deburred and cleaned, then sprayed with a steady stream of tiny glass beads via compressed air
- End result is a smooth, bright finish that’s flat and non directional
- Excellent for machined parts
- Great option for sheet metal parts, but large, thin sheet metal should be avoided in order to avoid warpage
- Materials: Aluminum, Stainless Steel and Copper
- Maximum part size: 6”x6”x6” (152.4mm x 152.4mm x 152.4mm)
- Minimum part size: Part must have at least one dimension that exceeds 2” (50.8mm)
- We recommend handling with gloves in order to avoid staining or smudging the parts
- As media blasting is a manual process, results may vary in terms of uniformity, especially when anodizing will be applied to your media-blasted part
- Can be digitally printed and silkscreened
- Can be permanently marked with laser marking and rubber stamping

Stock Finish: CNC Sheet Metal
![CNC Milling: Stock Finish CNC Milling: Stock Finish](https://www.protocase.com/products/cnc-machining/cnc-milling/img/Stock.jpg)
Stock Finish is similar to No Finish in that there is no additional finishing applied. The outer surfaces of your machined parts are left as the raw material (For example: plate, tubing or bar stock). Stock Finish parts may have scratches, as well as material identification print or stickers from the supplier.
Things to Consider:
- • Appearance is not decorative in any way. Stock Finish should only be chosen if the parts will not be on display.
