Why CHX Metal for Precision Aluminum Enclosures
Precision aluminum enclosures protect electronics, sensors, and mechanical assemblies in demanding environments — from factory floors to outdoor installations. We machine enclosures to tight tolerances with integrated sealing features, mounting bosses, and cable entry points.
- IP-rated sealing surfaces — O-ring grooves, gasket channels, and smooth sealing faces to IP65/IP67 standards.
- Heat-sink integrated designs — Finned heat sinks machined directly into the housing body — no secondary assembly.
- Multi-cavity enclosures — Internal compartments, PCB standoffs, and cable routing channels.
- EMI shielding preparation — Conductive surface prep for chromate conversion, electroless nickel, or tin plating.
- Mounting features — Integrated DIN-rail clips, wall-mount flanges, VESA patterns, custom brackets.

Materials & Tolerances
Choose the alloy for your application:
- 6061-T6 — suitable general-purpose; excellent anodizing response; easy to weld.
- 5052-H32 — high corrosion resistance for marine and outdoor use.
- 7075-T6 — high strength for ruggedized / industrial enclosures.
- Cast Aluminum (A356, A380) — for complex geometries in volume production.
Tolerances: ±0.005mm standard, ±0.005mm on mating surfaces, ±0.005mm on critical alignment features. Surface finish: as-milled Ra 1.6, bead-blasted Ra 3.2, anodized Type II / Type III.
Frequently Asked Questions
Can you make IP67-rated enclosures? Yes — we machine sealing surfaces to Ra 0.8 µm or better, with flatness within 0.005mm. O-ring grooves are held to ±0.005mm. We provide helium leak test reports on request for IP67-rated enclosures.
What is the large-format enclosure you can machine? Up to 800 × 600 × 400 mm on our 5-axis centers. For larger enclosures, we split the design into multiple parts and machine separately.
Do you provide surface finishing? Yes — anodizing (Type II/III), powder coating, bead blasting, polishing, electroless nickel, chromate conversion. All finishing is done by audited partners with full traceability.
Can you integrate heat sinks into the enclosure design? Absolutely — finned heat sinks, heat pipes, and even liquid cooling channels can be machined directly into the enclosure body. We optimize fin geometry for your thermal dissipation requirements.
