Custom Extrusion Heat Sink Manufacturer

Aluminium Extrusion Heat Sink

Extrusion heatsinks are typically made of aluminum, specifically aluminum alloys such as 6061 aluminum and 6063 aluminum. The most common design of extruded aluminum heat sinks is of a flat aluminum base with vertical radiating fins for increased surface area.

Aluminum extrusion heat sinks are cost-effective solutions for the majority of electronic cooling applications. Extruded heat sink profiles enable engineers to either select or start their design from a pre-tooled extrusion profile for the cooling solution.

PT’s aluminium extrusion heatsinks profiles range from simple flat back fin structures to complex geometries for optimized cooling and can be used for natural or forced convection with the use of a fan. Additionally, aluminum extrusions utilize the alloys 6063 and 6061 for improved thermal conductivity. To further optimize your heat sink’s performance, extrusion can be assembled with the heat pipes

PT heatsink is one of the leading aluminium heat sink manufacturer & supplier in China, we have been successfully supplying small company and big enterprise with our custom extrusion heat sink design and manufacturing service over 20 years, thanks to extensive know-how and expertise.

Extrusion Heat Sink Process

Extrusion Heat Sink Advantages:

Compared with other manufacturing methods, Aluminum extrusion heat sink offer the following benefits:

  • Most cost effective
  • Best thermal performance for forced convection
  • Extruded from A6063 with high thermal conductivity (209 W/m-K)
  • Good for medium- to high-airflows
  • Excellent surface finish and appearance
  • Length can be customized without new tooling
  • Secondary operation is easy to achieve
  • Cross cut extrusions offer omni-directional properties
