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
The working mechanism of cold extruding aluminum radiator is pretty simple. As mentioned above, you don’t need to pre-heat the block of the aluminum metal to working on it. Second, the cold forging process works the same as the stamping forming. So, you have almost the same machine set up for cold forging. First, you need to invest in a cold extrusion machine. You need a high-quality hydraulic press machine for cold extrusion. These are machines specially designed for all kinds of cold forming. The modern hydraulic press machine comes with automation features that make them easier to use. However, you need to get it right size depending on the size of radiators you want to produce. A complete cold forging process requires three main things – material, press equipment and mould. The material, in this case, is the aluminum metal. The die or mould comes in the shape of the radiator you want to create. The punch provides the need force in the press chamber to produce plastic deformation. The forming process is quite simple. Place the mould firmly in the press chamber and place the metal block. Then press the metal block with a punch against the mould to form the desired product. The force from the hydraulic press will be enough to make the aluminum material produce plastic deformation. That’s how aluminum radiators are constructed. If you are making just one size and shape of the aluminum radiator, then this set up is perfect for mass production.
There are many benefits that come with cold forging parts as opposed to traditional forging methods. One of them is cheaper production. The forming method reduces some of the steps, such as heating and oxidation, hence reducing the cost of production. Cold forging produces high strength parts with excellent mechanical properties. So, these are parts that can withstand tough condition. The other advantage of cold forging is a high production rate, making it ideal for mass production. At Cold Fording China, we use cold forging or impact extrusion to produce highly complex Cold Forged Parts in one or more pressing operation. Mechanical finish, annealing and surface coating complete the service range. The cold forged parts, including aluminium radiators, are structurally superior and very cost-effective. Our parts are widely used in all kinds of fields from industrial machines to automobiles, ships and aeroplanes. In close cooperation with our customers, we develop the desired parts according to the blueprints.
