Materials & Specifications
We machine CNC aluminum parts from 6061, 6061-T6, 7075, 2024, 5052, ADC12. Typical accuracy is ±0.005mm, warp control 0.1mm/300mm. Parts are manufactured to your 2D drawing or 3D model, in sizes from a few millimeters up to 1000mm envelopes, from single prototypes to hundreds of thousands of pieces per year.
Typical Applications
- heat sinks
- enclosures
- brackets
- optical benches
These are representative examples; we regularly take on custom geometries outside this list. Send your drawing for a feasibility check.
Our Machining Capability
Production runs on 3-axis and 5-axis vertical machining centers, CNC lathes, and Swiss-type automatic lathes. Fixtures are designed in-house for repeatable clamping, and programs are simulated before cutting to protect tight tolerances. Quality is verified, not assumed. First article inspection is mandatory on every new part number, and our quality engineers record CpK on critical dimensions for volume programs. With a coordinate measuring machine (CMM), surface roughness testers, and a temperature-controlled inspection room, measurement uncertainty is kept far below the tolerances we quote.
Surface Finishing Options
Available finishes include Type II and Type III anodizing (clear, black, and custom colors), sandblasting, wire drawing, laser engraving and silk-screen marking, zinc and nickel plating, passivation, and black oxide. Cosmetic parts are inspected under standardized lighting with defined surface criteria.
MOQ, Lead Time & Packaging
Quotations with manufacturability feedback are returned within 24 hours of receiving your drawing or 3D model. Prototypes ship in 3-7 days; production orders run 7-15 days depending on quantity and finishing. Export packing uses anti-scratch film, VCI paper, or custom trays so parts arrive ready for your assembly line.
Why Choose CHX Metal
Engineering support is included, not extra. Our CAM engineers review every drawing for manufacturability and cost reduction before quoting, and flag tolerance or finish decisions that materially affect price. Customers typically save 10-25% on program cost after this review.
