Custom Extruded Heat Sinks for Power Electronics & Industrial Systems

Short Description:

Material: 6063-T5 Aluminum Alloy

Surface Treatment: Anodizing

Application

Ideal for:

• Modular Power Systems: Inverters, UPS units, and DC-DC converters

• Industrial Drives & Controls: Servo amplifiers, PLC cabinets, and motor drives

• Renewable Energy Integration: Solar micro-inverters, wind turbine converters

• Test & Measurement Equipment: High-power load banks and RF amplifiers

Technical Specifications

Base Material: AL6063-T5 Aluminum (Extrusion-grade, optimized for thermal conductivity & structural rigidity)

Standard Profile Dimensions: 111.8 × 66.5 × 93 mm (Custom lengths up to 2000mm available)

Fin Geometry: 45.9mm fin height, 1.6mm fin thickness, 5mm fin pitch (Adjustable per thermal simulation)

Mounting Surface Flatness: ≤ 0.05mm over entire area (Critical for low thermal resistance)

Threaded Holes: M4/M5 threads with precise depth control (per GB/T 197 standard)

Surface Finish: Ra ≤ 1.6 μm (as-machined), optional anodizing (Type II/III)

Key Advantages

Optimized Extrusion Profile

Fin density & base thickness engineered for maximum heat dissipation per unit weight

Precision CNC Post-Processing

All critical surfaces (mounting face, thread holes, ports) machined to ±0.1mm tolerance

No Secondary Assembly Required

Threaded inserts & grounding points integrated during machining

Scalable Production

One-time mold cost amortized over volume; we handle tooling, extrusion, and finishing

Manufacturing Capabilities

Tooling Design & Mold Fabrication: Based on your CAD or thermal specs, we design the extrusion die

Aluminum Extrusion: AL6063-T5 billets extruded under controlled temperature/pressure for uniform grain structure

CNC Machining Center: 4-axis machining for mounting surfaces, threads, and interface features (ISO 2768-mK tolerance)

Deburring & Surface Treatment: Automated deburring + optional anodizing

100% Final Inspection: Dimensional check, surface roughness (profilometer), and functional testing
