An enclosure is primarily made by Die Casting. Die casting forces molten metal, usually aluminium, zinc or magnesium, under high pressure into a hardened steel die. It produces thin-walled parts fast once the die is paid for. Below is the full route to make an enclosure, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How an enclosure is made
The usual route, raw material to finished part. The amber step is where the enclosure gets its basic shape.
Alloy and tooling
Choose the casting alloy for the enclosure and make the pattern or metal die that forms the cavity.
Die Casting
Melt the metal and force it into the die under pressure, then let the enclosure solidify and cool.
Tooling High (steel die) Tolerance ±0.1 to 0.4mm Lead 6 to 10 weeks
Fettling and cleaning
Cut off the gates and risers, grind away the flash, and clean the raw casting.
Machining
Machine the mating faces, bores and datum surfaces to final tolerance: the as-cast surface is too rough for close fits.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Hole making
Drill, ream and tap the fixing and functional holes.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Heat treatment
Stress-relieve or harden the enclosure to reach the strength and hardness the design needs.
Tooling n/a Tolerance can distort Lead days
Surface finish
Plate, anodise or powder coat for corrosion resistance and appearance.
Tooling Low Tolerance adds 0.05 to 0.2mm Lead days
Inspection
Check critical dimensions and, for any part that holds pressure, leak-test before it ships.

PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for an enclosure at your volume, in your currency, are in the dossier.

What does an enclosure cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $5.9 to 10 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is an enclosure made from?
Common choices are 304 stainless; 6061-T6 aluminium.
What is the main process for an enclosure?
Die Casting. High-volume non-ferrous parts with thin walls, fine detail and a good as-cast finish, such as housings and brackets.
