The final "bombproof" enclosures for CHIME RED are Hammond Die Cast Aluminium Enclosures. Aluminium boxes were used to provide RF shielding of the internal components, while a black powder coated model was used to allow for laser engraving of labels.

One the required interface and I/O layout features had been modelled in SolidWorks, the hammond enclosures were CNC milled

Next, text labels were laser engraved on the enclosure. Careful alignment of the enclosures in the engraver was done using dry runs of the engraver tracing out the milled features using the visible red dot.
