A premium mechanical keyboard starts with its case. If you run a keyboard brand or organize group buys, choosing the right custom aluminum keyboard case manufacturer determines finish quality, consistency and whether you deliver on time.
How CNC Keyboard Cases Are Made
Cases are milled from solid aluminum plate. Top and bottom halves are roughed, finished on multiple faces, then deburred, bead blasted and anodized or e-coated. Brass or stainless weights are machined separately and often PVD coated or mirror polished.
Key Specifications to Define
| Item | Options |
|---|---|
| Layout | 60%, 65%, 75%, TKL, Alice, custom |
| Material | 6061 (most common), 7075 (stiffer, different anodize tone) |
| Finish | Sandblast + anodize, e-coat, spray coat, Cerakote |
| Weight | Brass, stainless, PVD, mirror polish |
| Mounting | Gasket, top mount, tray mount |
| Plate | Aluminum, brass, POM, FR4 (if outsourced) |
Prototype Before the Group Buy
Always order prototype units. Use them to verify PCB fit, gasket compression, sound, weight and color. Approve a physical color sample — anodized color varies slightly between alloy batches and finishing lines.
Common Quality Issues to Check
- Uneven anodizing or visible tool marks under the finish
- Gaps or steps between top and bottom case
- Thread damage on mounting screws
- Scratches from packaging and transport
Planning Batch Production
Lock the design after prototypes, confirm color standards, then schedule machining and finishing per colorway. Protective packaging for every case is essential.

FAQ
What is the most common material for keyboard cases?
6061 aluminum, chosen for machinability and consistent anodizing.
Can I order a few prototype cases first?
Yes. Prototype units should be approved before a batch for a group buy.
How do I ensure color consistency?
Approve a physical color sample and keep all parts of a colorway in the same alloy and finishing lot where possible.
