As a leading CNC Machining service provider, EMAR specializes in manufacturing high-performance heat sinks with micron-level precision. Our advanced CNC technology ensures optimal thermal management for electronics, industrial equipment, and automotive applications.

Why Choose CNC Machining for Heat Sinks?

CNC machining offers unparalleled advantages for heat sink production. The process allows for complex fin geometries, precise base flatness (within ±.05mm), and custom designs that maximize surface area for efficient heat dissipation. Our 5-axis CNC machines can produce aluminum heat sinks with fin thickness as low as .3mm while maintaining structural integrity.

Our Heat Sink Manufacturing Capabilities

EMAR's facility features state-of-the-art CNC machining centers capable of handling:

• Materials: Aluminum 6061/6063, Copper C110, and alloys
• Maximum dimensions: 800×500×300mm
• Surface finishes: Anodizing, powder coating, chemical conversion
• Tolerance: ±.02mm for critical dimensions

Quality Assurance Process

Every heat sink undergoes rigorous inspection including:

• 3D coordinate measurement for dimensional accuracy
• Thermal performance testing in controlled environments
• Surface roughness verification (Ra ≤ .8μm for mating surfaces)

With 15+ years of CNC machining experience, EMAR delivers heat sinks that meet MIL-STD-883 standards for military applications and ISO 9001 certified quality for commercial use. Contact our engineering team today for custom thermal solutions tailored to your specific requirements.
