2. What Is a Heatsink Production Line 

Essentially, a heatsink production line is comprised of a series of machines that produce aluminum heat sinks. Heat sinks transfer thermal energy away from electronics.

The production line begins with raw aluminum preparation. Aluminum forming machines then cut and form the fins and base. Lastly, the line has stations for assembly and surface finishing.

Heat sinks require extremely tight tolerances to function properly. Any error in dimension can cause poor heat dissipation. As a result, the forming and cutting equipment is servo controlled.

ASHRAE has more information on general heat dissipation requirements.

3. Equipments Composition

The main machines of heatsink production line are composed of:

• Aluminum extrusion press or skiving machine
• CNC machining center
• Fin forming press
• Drilling and tapping station
• Surface treatment line
• Cleaning and drying equipment
• Fixing assembly equipments
• Inspection equipments

Extrusion or skiving machine will form fin first. Secondly, CNC machining center will machine the mounting surface. Drilling and tapping station drill and tap screw holes after CNC machining.

At the same time, heatsink surface treatment equipment is responsible for surface treatment. Inspection equipments will inspect surface flatness and dimension tolerance of heatsink last.

To make the production process smooth, Bangwin Machine adopts PLC program control

4. Production Process

Process flow of heatsink production line:

Cold billet or strip enters the extrusion or skiving machine for fin forming. The extrusion or skiving machine produces equidistant fins.

The formed heatsink is placed in the CNC machining center for CNC machining. Drilling and tapping fixture punch screw holes on the heatsink.

Heat sink surface treatment equipments conducts surface treatment after drilling. Cleaning equipment cleans the heatsink surface.

Inspection equipments check heatsink contact flatness finally. So the quality of the heatsink can be guaranteed.

5. Self-control System

Speed and stability can be enhanced by automation. That is why Bangwin Machine is equipped with centralized control systems.

There are sensors to detect temperature, pressure and cutting accuracy. Digital displays are also provided to monitor the production information in real time.

Traceability is beneficial for quality control, so data of each batch will be recorded. What’s more, automated loading device can help reduce workers’ operation.

Factories can not only obtain higher production efficiency, but also minimize production risks with the above measures.

6. Technical Benefits

Bangwin Machine’s high performance heatsink production line has many advantages.

On the one hand, it can improve production efficiency. On the other hand, it can improve dimensional accuracy.

At the same time, automatic forming ensures that the distance between fins is uniform, so that the heat dissipation performance is stable. Moreover, the line adopts modular layout, which can expand production capacity.

According to the actual needs of customers, the production volume can be increased or decreased. Meanwhile, energy-efficient design helps to save energy.

7. Fields of Application

The following industries all need heatsinks:

• Consumer Electronics
• Power Supplies
• LED Lighting
• Electric Vehicles
• Industrial Automation

Data centers need cooling systems to keep processors working properly. And EV inverters need aluminum heatsinks for cooling as well.

Check out International Energy Agency (IEA) statistics about energy efficiency.

Demand for cooling will continue to grow as technology advances. With that in mind, manufacturers need flexible systems that can scale with production.
