Materials of Custom Heatsink

Materials of Custom Heatsink

  • Aluminum: Aluminum alloys such as 1050, 6060, 6061, and 6063 are common materials for the production of custom heatsinks for various applications. This material is lightweight which makes it more efficient and easily portable in large-scale applications. Aluminum has excellent thermal conductivity and corrosion resistance.
  • Copper: Copper has high heat conductivity compared to aluminum which makes them ideal for producing custom heatsinks. This material is non-corrosive, ductile, malleable, and heavier than aluminum.

Custom Heatsink Finishing

Hokare offers a wide range of custom heatsinks in numerous surface finishing options according to your application needs and preference. Here are some of the surface finishing we can offer:

  • Anodizing: It entails an electrochemical technique that transforms surface material into an aesthetic, hard-wearing corrosion-resistance oxide finish.
  • Powder Coating: The powder coating finish uses electric charges to fuse it into metal and operate dry powder.
  • Nickel Plating: This surface finish technique features yellowish-white appearances. Nickel plating finish provides excellent dimensional repeatability and solderability.
  • Chromate Finish: This technique involves transforming metal surfaces. It ensures exceptional corrosion resistance.

Custom Heatsink Manufacturing Process

Custom Heatsink Manufacturing Process

  • Die-Casting: A crucial technique for fabricating custom heatsinks with complex geometry. Die casting is a common process for an aluminum heatsink.
  • Skiving: This process is ideally suited for producing custom heatsinks with special attributes. It includes metal material slicing in numerous geometry and dimension depending on heatsink profile needs.
  • Extrusion: Most suitable and sustainable fabrication process for producing a wide range of custom heatsink designs. This process uses raw materials that make it extremely cost-effective. The extrusion technique ensures higher precision and mechanical qualities for different applications.
  • CNC Machining: Relatively flexible fabrication method that makes custom heatsinks with highly geometric complexity. This fabrication technique is precise, rapid, and effective.
  • Forging: Suitable fabrication technique for high production volume.

Custom Heat Sink Design

Custom Design

We leverage detailed thermal analysis and state-of-the-art CAD tools to design heatsinks that offer optimal cooling efficiency. Our designs typically achieve a thermal resistance as low as 0.5°C/W, ensuring your devices operate within safe temperature ranges even under high loads.

Custom Prototypes

Utilizing cutting-edge 3D printing and CNC machining technologies, we’re capable of producing prototypes with intricate details and tolerances as tight as ±0.05 mm. This level of precision ensures that each prototype not only visually represents your concept, but also functionally tests its viability.

Custom Fabrication

Hokare manufactures custom heatsinks in ISO certified, state-of-the-art facility. Our custom heatsinks are manufactured, assembled, and designed into a full assembly. We test every heatsink for structural integrity and thermal performance.
