This oval extruded aluminum instrument box is integrally extruded from 6063 aluminum billet to form seamless hollow elliptical aluminum profile blanks.
Our full in-house production workflow covers high-temperature extrusion forming, CNC fixed-length saw cutting, precision CNC milling for end holes, mounting screw posts, PCB internal slots and wire outlet cutouts. After full deburring and ultrasonic degreasing cleaning to eliminate metal chips and oil residue, we apply fine matte sandblasting then colored hard anodizing in lake green finish.
All CNC machined features maintain tight ±0.02mm dimensional tolerance. As a professional custom aluminum enclosure manufacturer, we provide full OEM custom service to adjust outer dimensions, internal slot layouts, hole positions and anodize colors per customers’ technical drawings or physical samples, supplying standardized colored anodized aluminum power supply housing and cnc machined elliptical aluminum case for global electronics clients.
CNC Machining Custom: Custom drill holes, PCB slots, screw posts, cable outlets according to internal assembly demands.
Surface Finish Custom: Adjust sandblast fineness, customize anodize color including silver, black, lake green and other tones.
Marking Custom: Laser engraving, silk screen printing brand logos, model numbers on aluminum housing.
Packaging Custom: Custom anti-scratch foam inner lining and neutral export cartons for bulk shipment.
Product Advantages
Precision CNC machining with ±0.02mm tolerance eliminates loose assembly and misaligned screw hole issues of low-precision aluminum shells.
Integrated seamless extruded oval structure avoids water and dust intrusion gaps of split-welded casings.
Colored hard anodized coating resists scratches, corrosion and fading, solving short service life of thin ordinary oxidation finish.
Complete one-stop in-house production shortens lead time and avoids inconsistent quality from multiple outsourcing suppliers.
Flexible small-batch trial order custom service removes high minimum order quantity barriers for new product prototype development.
Pre-machinable internal PCB mounting slots save extra accessory installation costs for electronic assembly.
Quality Control
Raw Material Inspection: Alloy composition testing of 6063 aluminum billets before extrusion to guarantee stable material performance.
Mid-process Dimensional Testing: Digital caliper and micrometer measurement after saw cutting and CNC milling to lock ±0.02mm tolerance.
Surface Pre-treatment QC: Inspection after ultrasonic cleaning to ensure zero residual oil, metal burrs and particles.
Finishing Surface Check: Visual inspection for uniform sandblast texture, consistent anodize color and coating thickness.
Finished Product Full Inspection: Test screw hole fit, slot smoothness and shell flatness before packaging.
Batch Inspection Report: Provide detailed dimensional and surface test data sheets for every bulk order.
FAQ
Can you make custom-sized extruded oval aluminum enclosure based on my drawings?
Yes, our OEM custom service supports full size, hole and internal structure adjustments following your drawings or samples.
What minimum order quantity do you require for custom hollow aluminum electronic shell prototypes?
We accept low-volume trial orders for prototype testing with flexible MOQ for new product development.
What other anodize color options do you offer besides lake green?
We provide silver, black, gold and other custom colored hard anodizing upon request.
What precision tolerance can your CNC machining achieve for elliptical aluminum case?
All machined holes, slots and cutouts are controlled within strict ±0.02mm tolerance.
How long is the production lead time for oval extruded aluminum instrument box orders?
Sample lead time is 3–7 working days; mass production takes 10–18 working days depending on order quantity.
