CNC Heatsink

We are a manufacturing company integrating aluminum profile extrusion and CNC precision processing, focusing on customizing various CNC heatsink heat sinks with complex structures and superior performance for customers. This type of heat sink is not only fine in structure, but also has high thermal conductivity and beautiful appearance. It is widely used in high heat density products such as 5G communication equipment, automotive electronics, medical equipment, power inverters, etc.

By combining high thermal conductivity aluminum alloy extrusion process with multi-axis CNC machining technology, we can produce various high-precision CNC heat sinks, including customized parts with gears, guide grooves, positioning holes, and thermal interfaces to meet the diverse needs of different customers in heat dissipation efficiency, assembly compatibility and structural strength.

Case: Double-sided positioning high-precision CNC Heatsink module processing
Material: 6061-T6 aluminum alloy
Size: 180mm × 120mm × 25mm
Requirements: Complex steps and through holes on both the upper and lower sides, with an accuracy of up to ±0.01mm
Surface treatment: Anodized black, no water marks, no brushed lines, no bubbles
Difficulty analysis:
Double-sided positioning is difficult to match: the parallelism of the upper and lower fixtures and the accuracy of repeated clamping need to be precisely controlled;
Cutting force can easily cause deformation of thin areas: we adopt the "layered light cutting" strategy to ensure that the heat dissipation teeth do not deform;
Anodizing pre-treatment requirements are strict: the whole process controls oil pollution, oxide film uniformity and edge smoothness;
The heat dissipation capacity of the area where local heat is concentrated needs to be optimized in a targeted manner, which is solved by improving the tooth shape distribution and diversion design.
This batch of CNC heatsink products finally passed the customer's 100% inspection standard and has been successfully applied to communication base station equipment, with stable operation and excellent temperature rise performance.
