Heat Sinks: The Cold Forging Of Aluminum Heat Sink

Heat Sinks: The Cold Forging Of Aluminum Heat Sink

If you have been using electronic and some electrical devices, you must have come across heat sinks. These are metallic plates that are used in electronic devices and works by dispensing produced heat. Did you know that heat sinks are made from cold forging? That’s true.

But how does cold forging aluminum heat sink? This article is providing you will also details you need about the cold forging of aluminum heat sinks. This is how they are cold-forged:

Selecting The Right Aluminum

The first step into cold forging aluminum heat sink is selecting the right aluminum material. The work of heat sinks is to keep the electronic device cool by dispensing the produced heat. This means the choice of aluminum must have very good heat conduction properties. That’s one of the most important factors to consider.

Designing and Making Molds

The second step is the design of the molds. There various sizes and shapes of the heat sinks, and thus there are all kinds of mold designs. So, you need to get the right mold for the kind of heat sinks you want to produce. There are special machines that work on the design and making of the molds s. The design is done on the computer, and the making is done by machining equipment.

Placing Molds and Materials

The third step in cold forging aluminum heat sink is organizing mold and workpiece to start the forging process. The mold must be fixed on the machine to ensure its firm during the compression. In some cases, you might have molds both on the striking surface and on the punch. Then place the material being forged on the mold. Make sure that the material is properly lubricated to make the process easy.

Forging

With the die and the material well, it’s time to strike and for the expected heat sink. A hydraulic press machine is used in the forging. The hydraulic system produces the hydraulic pressure that’s direct on the hammer or the punch. The pressure causes the metal to develop plastic deformation hence taking shape and size of the molds. That’s how heat sinks are formed.

Finishing

The last stage is finishing the cold-forged-aluminum heat sink. There are machines simply made for the finishing work. They will fix all the awkward parts to give the product the expected shape.

Properties of Cold Forged Steel Making It Popular

Properties of Cold Forged Steel Making It Popular

The vast application of cold forged steel is one of the reasons why it has grown very popular in the forging industry. Steel is one of the hardest metals, and the availability of various steel alloys with better properties makes it popular in the metal manufacturing industry. In this article, we are going to look at some of the major properties making cold forged steel popular. Read more below.

High Ductility

One of the biggest cold forged steel properties is ductility. Ductility is the ability of the metal to withstand the bending forces it is exposed to. In the metallic industry, whether in the construction industry or automobile, metallic parts are exposed to a lot of bending stress, and this could cause breakage or fractures. But steel can withstand these forces because of the high ductility properties.

Impact Toughness

The impact toughness is another cold forged steel property making it popular in metallic parts manufacturing. Impact resistance is the ability of the metal to withstand an impact like fall and so on. Steel, with its impact toughness, can withstand such conditions hence increasing the parts’ lifespan.

Fatigue Strength

When the metallic part is exposed to rough conditions for a long time, they are likely to start wearing out. That’s why fatigue resistance is an important feature to look for metallic parts. Cold forged steel offers one of the best fatigue resistance properties in the market. This is why steel forging parts can last for a longer time.

Tensile Strength

Tensile strength is another property making cold forged steel popular in the market. The exposure of the metallic parts to tension can cause a lot of damages, including breakages and warping. But that is not the same with the cold forged steel. It offers high tensile strength to become one of the best choices in the market.

Better Wear Resistant

Wear resistance is one of the crucial properties you need to consider when it comes to cold forged parts. This is one of the properties that make the parts last for a long time. You need to consider, among many other things, how long the forgings will serve you because it will give you value for money. Cold forged steel offers one of the best wear resistance properties for all forged metals.
