Product Description

This custom CNC aluminum middle frame is manufactured from 6063-T5 extruded aluminum profile, designed as the structural border for compact portable smart electronic terminals and portable audio equipment.
The blank rectangular hollow aluminum profile is precisely cut to target dimensions, then processed by multi-axis CNC milling to form all functional cutouts including Type-C charging port, microphone pinholes, physical button slots, internal locking buckles, positioning bosses and motherboard fixing grooves.
After full deburring, uniform linear brushed texture is applied on both inner and outer walls, followed by degreasing cleaning and natural clear anodization to boost anti-corrosion performance and metallic texture.
As a professional OEM manufacturer, we deliver one-stop custom service for all aluminum enclosure frames, supporting fully personalized dimension, cutout layout and surface finish based on customers’ technical drawings or physical samples. All finished aluminum terminal borders pass 100% dimensional tolerance test and full visual inspection before shipment.

Product Advantages

• Avoid unstable precision from ordinary machining: Multi-axis CNC equipment ensures ±0.02mm tight tolerance, perfect matching with PCB and screen assembly to eliminate assembly gap issues.
• Solve weak structural problems of thin aluminum housings: Adopt 6063-T5 tempered extrusion aluminum with stable rigidity, no deformation after long-term use of portable devices.
• Fix rough metal surface burr defects: Full inside & outside deburring + uniform wire brushing, no scratch or sharp edge damage to internal electronic components.
• Eliminate easy oxidation and fading problems: Standard natural anodized treatment improves scratch resistance and anti-corrosion performance for long-term product appearance.
• Cut multi-supplier coordination trouble: We are integrated manufacturer from extrusion to finished frame, one-stop custom service to reduce communication and delivery delay risks.
• Avoid unqualified outgoing products: 100% full inspection for dimension and appearance, reduce customer after-sales defective rate.

Quality Control

1. Raw material incoming inspection: Test 6063-T5 aluminum alloy composition and extrusion flatness before production.
2. In-process mid-test: Real-time dimension sampling inspection during CNC milling to guarantee machining tolerance.
3. Full deburring visual check: Inspect all inner and outer edges to remove residual burrs completely.
4. Surface treatment QC: Uniform brushing texture & anodizing thickness test to avoid uneven color or coating peeling.
5. Final finished product 100% full inspection: Full dimensional measurement and comprehensive appearance check for each aluminum middle frame.
6. Random sampling assembly test: Match with standard PCB to verify the accuracy of internal buckles and positioning structures.
7. Independent quality report can be provided for bulk OEM orders upon customer request.
