  Sinda Thermal can offer 1 and 3 FT length and most common use heatsink extrusions applied in many thermal management. Heatsink extrusions are manufactured by pushing the aluminum ingot through the steel tooling to make the custom shape, then cut off and machining for the specific dimensions; heatsink extrusions usually supplied with a surface finish such as black anodizing or clear anodizing to enhance its thermal performance. Sinda Thermal extruded heatsinks are designed to provide the optimal thermal performance.

  Aluminum heat sink extrusion is the most common process and cost efficient thermal solution for most electronic devices and industrial applications. Aluminum extruded heat sink has lightweight, good thermal performance, cost-efficient, easily manufacturing, etc. benefits. The aluminum extruding process is to put the heated aluminum ingot to the customized tooling die to get the designed shape and dimensions, then cut off the extrusion profiles to get the wanted length; usually the further processes such as CNC maching, drilling, anodizing are needed to complete the custom design and dimensions.

Production Process:

Extruded heatsinks are most widely used in thermal management for its most cost saving, lightweight, and good conductivity. Heatsink extrusions usually are manufactured by the below a few steps:

1. Pushing the aluminum billets through the steel die to get the extrusion shape

2. Cutting off and cross cut if needed

3. CNC machining to complete the specific dimensions and holes

4. Anodizing and packing
