CNC machined aluminum heatsinks are essential for efficient thermal management in industrial electronics. Crafted from high-quality aluminum alloy (6061/6063) via precision CNC machining, our heatsinks deliver exceptional thermal conductivity to keep electronic components cool. The anodized black surface not only boosts corrosion resistance but also ensures a sleek, professional appearance.

With a tolerance of ±0.05mm, these CNC machined aluminum heatsinks provide a precise fit for industrial devices, enabling seamless integration into assemblies. Each unit undergoes 100% dimensional inspection with calipers to guarantee accuracy. Whether you need standard sizes (such as length 100–300mm with customized width) or fully tailored heatsink designs, we offer a MOQ of 50pcs, sample lead times of 3–7 working days, and bulk deliveries within 10–15 working days.

Ideal for power supplies, LED fixtures, and other industrial electronic applications, our anodized black aluminum heatsink combines CNC precision with durable performance. Customization options for dimensions, fin geometry, and surface treatments make it easy to meet your specific thermal management needs.

Our CNC Machining Facilities & Capabilities

At JXD Machining, we operate a 5,000+ square meter fully integrated CNC machining facility, armed with a fleet of 40+ advanced pieces of equipment to meet diverse customization demands. Our core equipment lineup includes: 12 sets of 3-axis CNC milling centers (Haas VF-2), 8 sets of 4-axis machining centers (DMG MORI CMX 1100 V), 5 sets of high-precision 5-axis milling centers (MAZAK Variaxis i-700), 10 sets of CNC turning lathes (Okuma LT2000-MY), 3 sets of Swiss-type automatic lathes (Citizen M32), and a complete Surface Treatment line covering anodizing, sandblasting, and powder coating.

 

We excel in both flexible rapid prototyping and stable high-volume production: we support 1-50 pieces of rapid sampling and 10,000+ pieces of mass production, with the ability to process over 20 Materials including Aluminum(6061/7075), Stainless Steel(304/316), Titanium alloy (TC4), Brass, and engineering Plastics ( POM  / PEEK ). With a strict tolerance control range of ±0.005mm to ±0.05mm, we easily handle complex structures such as deep holes, curved surfaces, and multi-step components, serving key industries like Electronics, Medical devices, Consumer Products, and Industrial Automation.

On delivery efficiency, we balance speed and precision: rapid prototyping takes 3-5 working days, small-batch production (50-500 pieces) is completed in 7-10 working days, and large-volume orders are delivered within 15-25 working days (adjustable based on order scale and complexity).

Quality Assurance

At JXD Machining, our strict, streamlined quality & outbound process—backed by advanced tools—guarantees compliance:

Incoming Check: Verify raw material certificates + sample tests (hardness, composition) to rule out defects.

In-Process Inspection: Spot-check critical stages with CMMs to validate tolerances (±0.001mm) early.

100% Final Test: Full dimensional, surface roughness, and functional checks—only passers move forward.

Outbound Review: Secure packaging + batch labeling; test reports/certifications included for traceability.
