Extruded Aluminum Enclosures

Extruded aluminum enclosures are made of two aluminum extrusions (or side rails, as they're also known), along with a front, rear, top and bottom panels.

Protocase currently offers two stocked 6063 aluminum extrusions:

Extruded aluminum enclosures are extremely useful for creating PCB enclosures, as the extrusion's slots allow for easy mounting of printed circuit boards.

Protocase can build your completely customized extruded aluminum enclosures in 2-3 days, in the quantity you require (there is no minimum order - ever!). We offer a wide variety of custom finishes in order to achieve a professional, high-quality look, as well as custom cutouts, fasteners and other hardware.

Materials:

Our stocked extrusions are 6063 Aluminum.

Top and bottom panels specifically must be 0.064" (mm) 5052 aluminum in order to fit the aluminum extrusion's slots.

The front and rear panels in an extruded aluminum enclosure are also typically 5052 aluminum, though any of our stocked sheet metal may be used instead.

Front & Rear Panel Options:

Choose from one of our six standard faceplate styles - or design your own:

2U Profiles:

You can mix the panel types to have different combinations, as well as make other customizations to the panels. For instance, you can extend the sides of the front panel in order to mount the enclosure in a rack, or you can bend out the bottom flanges to use as mounting flanges for securing the enclosure in position.

Fasteners:

We use #6 thread-forming screws for attaching the front and rear panels.

Self-clinching fasteners cannot be inserted into an aluminum extrusion unless a particular area on the extrusion is CNC machined first in order to insert the fasteners.

Fasteners can be installed in any of the enclosure's panels, as long as the fastener doesn't interfere with the extrusion once the enclosure is assembled.

Finishes:

The aluminum extrusions (side rails) come in a bare aluminum mill finish. Powdercoat and/or chem filmed can be applied to the extrusion as a secondary finish. We do not recommend applying anodizing to aluminum extrusions.

The panels in an extruded aluminum enclosure can have many of our finishes applied (either for all four panels, or part-by-part):

Graphics & Permanent Marking:

The panels in an extruded aluminum enclosure can have graphics and other marking applied:
