Product Introduction
We are a professional aluminum extrusion profile and CNC processing manufacturing company, committed to providing customers with high-performance extruded heat sink products, widely used in LED lighting, power modules, new energy vehicles, 5G communications, inverters and other industries.
Our extruded heat sink uses high thermal conductivity aluminum alloy, which is extruded to form a mixed heat dissipation structure, and then combined with CNC precision machining for size trimming, drilling, tapping, surface treatment, etc., to improve the structural stability and thermal management performance of the radiator. We can develop molds and mass-produce personalized radiator solutions according to customer drawings or functional requirements.
Sharing of details on processing difficulties: High-tooth density heat sink
An industrial customer customized an extruded heat sink for high-power power supply equipment. The teeth are fine and the structure is complex, and the processing challenges are significant:
Material: 6063-T5 aluminum profile
Size: 310mm × 140mm × 45mm
Structure: 65 pieces of 1.1mm thick heat dissipation teeth on the top, with extremely small tooth spacing
Process requirements: milling at both ends, processing M4 countersunk holes, deep processing of slots, flatness required < 0.04mm
Process challenges:
The heat dissipation teeth are too dense, the CNC clamping space is insufficient, and conventional processing methods are prone to deformation;
The slot is close to the root of the tooth, the tool vibration is large, and the tool life is short;
The multi-hole position is centered and symmetrical, and it is required to be clamped all at once, and the processing accuracy is high. ±0.01mm
Solution
Use customized vacuum adsorption fixture to improve clamping stability and avoid crushing heat dissipation teeth;
Use micro carbide tools + low-speed multiple cutting to control thermal deformation and chattering;
Programming uses the same reference point to automatically locate the hole distance, and cooperates with the coordinate tool setting system to process and form in one time;
Finally, three-coordinate measurement + film thickness detection is used to ensure that the product meets strict quality requirements.
Customers feedback that this batch of extruded heat sinks has high installation accuracy and excellent thermal conductivity, and has been supplied in batches for more than 18 months.
