Bare Metal Finish

Protocase offers three basic bare finishes for aluminum and stainless steel - "No Finish", "Grained Finish" and "Vibratory Finish".

No Finish: CNC Sheet Metal

No Finish
No Finish
  • 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

Grained Finish: CNC Sheet Metal

  • 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
  • Can be digitally printed and silkscreened

Stock Finish: CNC Sheet Metal

Stock Finish
CNC Milling: Stock Finish

Stock Finish is similar to No Finish parts in that there is no additional finishing applied, except the outer surfaces of your machined part are the raw material that was milled (For example: 0.5” plate or square tubing). 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.
