Extruded Aluminum Heat Sink with CNC Machining

Precision Extruded Aluminum Heat Sink with CNC Machining

Engineered for Seamless Thermal Integration

 

 

Transform your thermal management with Extruded Aluminum Heat Sinks with Precision CNC Machining – where advanced extrusion meets surgical-grade machining. We manufacture integrated thermal solutions that eliminate interface losses between your components and heatsink, delivering up to 30% lower thermal resistance than assembled alternatives. Our CNC-machined extruded heat sinks combine complex aluminum profiles with micron-level flatness machining, ensuring perfect thermal contact for IGBTs, power modules, and high-flux LEDs. From prototype to production, we engineer custom aluminum thermal solutions that fit your mechanical, electrical, and environmental constraints – not the other way around.

This Extruded aluminum heat sink with CNC machining has the following features:

 

Zero-Interface Thermal Transfer: CNC-machined mounting surfaces (Ra ≤0.8μm) ensure >95% component contact

Unified Design Integrity: Eliminates secondary assembly – heatsink is the structural component

High-Density Integration: Tapped threads, wire channels, and connector cutouts machined in situ

Active-Grade Passive Cooling: Optimized fin geometries achieve 0.15–0.8°C/W thermal resistance

Harsh Environment Ready: Type III anodizing withstands salt spray (500+ hrs ASTM B117)

EMI/RFI Management: Integrated shielding grooves and grounding points

Vibration Resilience: Monolithic construction survives 8G shock loads

 

 

Our CNC-finished extruded heat sinks solve thermal challenges in:

 

Motor Drives & Inverters: IGBT mounting with coolant channels

5G RF Power Amplifiers: EMI-shielded enclosures with heat spreading cores

Industrial LED Luminaires: IP67-rated housings with COB mounting surfaces

EV Charging Systems: Liquid-cooled DC/DC converter plates
