Professional CNC Machining for Heat Sinks & Thermal Management Services

AOOM Technology delivers comprehensive cnc machining for heat sinks & thermal management solutions built on decades of precision-manufacturing expertise. Our ISO 9001:2015-certified facility in China operates 80+ advanced CNC machining centers supported by a team of experienced mechanical engineers and metallurgists. From single prototype validation to full-scale production runs exceeding 100,000 units, every project undergoes the same rigorous engineering review — ensuring that material selection, tool-path strategy, and quality-control protocol are optimized before the first chip is cut. We partner with clients across automotive, aerospace, medical, energy, and industrial automation sectors to produce mission-critical components that demand uncompromising accuracy, repeatability, and surface integrity.

Key Technical Specifications

• Materials: Aluminum 6061-T6, 6063-T5, 1050, and C11000 copper with thermal-conductivity verification reports
• Fin geometries: Straight-fin, pin-fin, flared-fin, cross-cut, and proprietary micro-channel arrays for optimized convective and radiative heat transfer
• Precision: Base flatness within 0.02 mm (critical for TIM bond-line thickness), fin spacing uniformity ±0.05 mm, and surface finish Ra 0.4 μm
• Equipment: 12-axis CNC machining centers with high-speed spindles (up to 30,000 RPM) for rapid fine-fin cutting in soft metals
• Post-processing: Type II anodizing, black anodize for emissivity enhancement, nickel plating, and thermal-interface surface lapping

Applications

• Power electronics: IGBT coolers, inverter heat sinks, and rectifier cold plates for EV traction drives and solar inverters
• Telecommunications: RF amplifier thermal bases, base-station heat sinks, and 5G mmWave module coolers
• LED lighting: High-bay luminaire heat sinks, stage lighting thermal cores, and automotive headlamp coolers
• Medical laser systems: Diode laser mounts, CT tube coolers, and MRI gradient-coil cold-plate assemblies

Quality Assurance

Every component machined at AOOM Technology is manufactured under a strictly enforced ISO 9001:2015 quality management system. Our quality-control workflow begins with incoming material inspection and certification verification, continues with in-process probing and statistical process control (SPC) during machining, and concludes with a comprehensive final inspection. We deploy coordinate measuring machines (CMM) with Renishaw probing systems to verify critical dimensions, geometric tolerances, and surface finish parameters against your engineering drawings. First-article inspection (FAI) reports are standard for every new production run, and material certifications are archived for full traceability. For clients in regulated industries, we also support PPAP (Production Part Approval Process) documentation and AS9100D aerospace requirements.
