What is Cold Forging


In the metal manufacturing industry, there are many forming processes that are used. But cold forging, also called cold extrusion, is among the most popular methods. That's because of the many benefits it offers over most of the available processes, such as hot forging, among others. Cold forging is one of the manufacturing processes that take fewer steps to produce a product. As the name suggests, cold extrusion is performed at room temperature. So, it's simply a volume forming process that's carried out below the metal's crystallization temperature. So you don't need to invest in the expensive medium-frequency induction heating to heat the blanks. With that, it means that you will be spending less energy on the entire manufacturing process with this method. This is one of the biggest reasons cold forging is growing popular. Cold extrusion basically works the same way as the stamping process. You need to force to work on the workpiece to produce the required product. The setup includes three main elements -the material, molds/dies, and the press equipment. The material used could be any metal. This includes steel, aluminum, and stainless steel, among others. The mold or dies differs depending on the shape and the size of the product being formed.

The Advantages of Cold Forging


Cold forging or cold extrusion is growing popular because of the many advantages it process offers. There are many reasons manufacturers prefer cold forging over hot forging, precision forging, temperature extrusion, and so on. One of the advantages of cold forging is higher energy saving compared to other available options. As mentioned above, cold forging works at room temperature. So, you don't need to pre-heat the material or workpiece you are working on as hot forging. This means the total energy needed to manufacture products is reduced with cold extrusion. That makes the method economical for manufacturers and cheaper tools. The other advantage of cold forging is surface finish quality. With this cold extrusion, you produce products that need very little or no finishing at all. This means you will be avoiding most of the costs associated with the finishing work. So, if you are in the business, this means more money and affordable products. Another advantage of cold forging is material saving. Unlike most of the manufacturing processing methods, cold extrusion produces near-net shapes. It means you will be having very little or no material wasted during the entire manufacturing process. You will save money on the cost of material and hence, more profits than hot forging. The other benefit of cold forging is close dimensional tolerance.

    There has been a huge increase in the use of electronics in the manufacturing of all modern machine. This comes come at the backdrop of a massive automation campaign of machines. But this development has also caused a demand for aluminum radiators. Their work is simply to remove heat produced from the electronic circuit to reduce damages. For the longest time, hot extrusion has been the technology used for the production of aluminum radiators. The process requires the use of heat aluminum, mostly using the medium-frequency induction heating, to achieve plastic deformation. The manufacturer also used oxidation to maintain the quality of metal. In overall, the cost of producing these parts becomes high with hot forging. Cold extrusion or cold forging, is among the most advanced extrusion technologies in the industry. It has grown popular in the industry because of the numerous benefits it offers over the method. One of the major reason why manufacturers are going for cold forging is the ease of automation in production. With its few steps to produce forged parts, it is very to almost fully automate its functions. As the name suggests, cold extrusion simply means forging at room temperature or temperature below crystallization. Unlike the traditional forging methods such as warm forging where the blank is heated first, cold forging doesn’t. You just work on the workpiece directly or heat slightly if it’s an extremely tough metal to make it easier for the extruding machine. But aluminum is a soft metal hence no heating is required
