Manufacturing of Mac Pro

Deep draw stamping.

The enclosure is drawn through a series of dies that progressively stretch the aluminum into something approaching the final shape of a Mac Pro

The initial ingot of material

Apple uses a CNC center to profile the outside shape of the Mac Pro. This step brings the part into high-precision tolerances and removes the relatively rough surface finish produced in the deep draw process.

Profiling

Robots spin the Mac Pro's enclosure around polishing wheels to produce a near-mirror surface finish.

External surface

Milling

In order to prevent damage during the upcoming milling operations, the freshly polished enclosure is coated with a surface protection film.

The enclosure is back in a CNC center where the I/O slot is cut out.

Anodizing

Electrical current is run through aluminum in an acid bath, causing oxygen molecules to bond to aluminum producing a thin, uniform layer of aluminum oxide.

In this process, robotic blast system uses air pressure to force glass beads to uniformly rough up the surface.

This is a triangle cooling tower inside the Mac Pro. It is extruded from aluminum and has features like holes and threads added later.

Making PCBs

Hand assembly

The final process is the laser operation.
