Cold forging  heat sinks

Cold forging technology is to recrystallization temperature of profile below room temperature forming processing. Cold forging material mostly is aluminum or copper.

Cold forging is a highly precise manufacturing process in which the workpiece is formed under high pressure and low temperature. 

Fin arrays are formed by forcing raw material into a molding die by a punch. The process ensures that no air bubbles, porosity or other impurities are trapped in the material, and thus produces products with exceptionally high quality.

Shape & Materials

Cold forged heat sink is a good choice for casting complex shapes with excellent thermal conductivity. The cold forging process allows an almost perfect straightness of more fins per square millimeter. 

The shapes of cold forged heat sink include plate fin heat sink, round pin heatsink and oval fin heat sinks.

The manufacture of forged heat sinks are well suited to the use of copper because the copper heatsink can be shaped without high temperatures and can be formed with minimal damage. 

Cold forging heatsink manufacturing can often include secondary processing operations such as holes, chamfering and steps to reduce unnecessary waste.

Benefits

1. Improved mechanical strength

2. Improved surface finish

3. Better control of tolerance

4. Efficient use of raw materials

5. Reduced energy consumption

6. High production rate

7. Low overall cost

Compared To Zipper Heatsink, the Advantages of Cold Forged Heatsink

Unlike zipper-fin or bonded-fin heat sinks, the pins on a forged heat sink are an integral part of its base plate – they are simply squeezed out of the base. There is no air gap or thermal interface between the pins and the base. Heat can dissipates easily from the base to the pins without additional resistance.

Application

The heatsink adopts cold forging technology for integrated design and production, with low thermal resistance and good heat conduction effect, which effectively guarantees the timely export of heat and achieves the ultimate heat dissipation effect. 

In addition, the cold forging heatsink has good mechanical properties, high productivity and high material utilization rate, and is particularly suitable for mass production, thereby reducing production costs.

So cold forged heatsinks are very popular and widely used in the field of consumer electronics, Led, power, medical, telecommunications and automotive industries etc.

It is necessary to go beyond geographical restrictions, focus on the global market, adjust the strategic layout, while stabilizing the domestic competitive position, go to the world, actively participate in the market competition in the international Factory Supply Black Anodized Cold Forging LED Heat Sink manufacturing field, and create a new level of growth. The company insists on taking the road of high-quality development, giving full play to our advantages and making continuous progress. In the future, we will further expand the scale of the enterprise. While improving economic benefits, the company will pay more attention to the construction of internal management system, actively explore the international market, strengthen logistics management, and improve the technological content of products and the level of the enterprise.
