Machined Engraving

Protocase offers machined engraving on sheet metal enclosures and parts using our high-speed 3-axis vertical CNC milling machine. Also known as machined etching, this process offers permanent marking on your enclosure, panel or part, which is ideal for labeling, branding or schematics.

Machined engraving can be done on aluminum, stainless steel and cold rolled steel.

Machined engraving is completed after a panel or part is cut, but before it is bent. Machined engraving is ideal for flat areas of an enclosure, however they may also be put over a bend line (although this may result in some distortion).

Our 3-axis milling machine places certain limitations on the size of sheet metal parts that can be engraved. The maximum size of sheet metal parts we are able to engrave in a single setup is 26" x 16" (660.40mm x 406.40mm).

Engraving Depth:

The depth of Protocase's machined engraving is standard, set at 0.010" (0.25mm).

Our standard machined engraving depth can vary depending on the material used, as well as any secondary finish applied post engraving. For example, stainless steel and cold-rolled steelís stiffness will produce a shallower depth compared to aluminum, which is a more lightweight material.

Font Capabilities:

Maximum font size is only limited to the size constraints of our milling machine (see above). For ideal legibility, we recommend using a font with a size no lower than 10pt.

Finishes:

We offer machined engraving on a variety of finishes:

Aluminum:
  • Smooth Polyester Powdercoat: Both pre- and post-painting (flat parts recommended)
  • Grained Finish: Post-brushing
  • No Finish:
  • Anodizing*: Both pre- and post-anodizing (Note: machined engraving after anodizing will mean it is no longer corrosion resistant)
Stainless Steel and Cold-rolled Steel
  • Smooth Polyester Powdercoat: Post-painting (flat parts recommended)
  • Grained Finish: Post-brushing
  • No Finish:

*Anodizing is an electrochemical process that converts the metal surface (aluminum, typically) into a decorative, durable, corrosion-resistant, anodic oxide finish. Although anodizing is a finish we offer, it is performed externally. As a result, our standard lead time does not apply - turnaround times are typically 1-2 weeks.
