- Prototype, low-volume, and batch production
- Tight tolerance machining according to drawing requirements
- Custom surface finish and color
- Thread inserts, assembly, and packaging support
- Export packaging for international shipment
Manufacturing Workflow
- Review 3D model, 2D drawing, material, tolerance, and finish requirements
- Confirm manufacturability and machining strategy
- Prepare CNC programming and tooling
- Machine roughing and finishing operations
- Deburr, clean, and inspect dimensions
- Apply surface treatment if required
- Final inspection and packaging
Selection Notes
This aluminum CNC housing is a suitable demo product for showing the capability of custom CNC milling services. For higher strength requirements, 7075 aluminum may be selected. For better corrosion resistance in harsh environments, 316 stainless steel or titanium may be considered. For lightweight cost-sensitive parts, 6061 aluminum remains one of the most practical choices.
Customer Reviews
The aluminum CNC housings matched our drawings very well. Critical hole positions and threaded features were accurate, and the anodized finish was clean and consistent. This sample is a good example of what we expect from a precision CNC supplier.
We ordered prototype CNC machined aluminum enclosures for an electronics project. The parts arrived with smooth edges, accurate dimensions, and professional packaging. Communication about tolerance and surface finish was clear.
The demo housing shows strong machining capability for small-batch custom parts. The tapped holes, pockets, chamfers, and bead-blasted anodized surface were all finished properly.
