Die castings made of non-ferrous metals such as aluminium, magnesium, zinc, etc. are omnipresent in everyday life. Toys, aluminium rims and kitchen utensils, but also machine and engine housings are made using either a hot-chamber or cold-chamberdie casting machine. Die casting machines are fast and efficient. It only takes a few steps from the raw material to the finished product. Smooth surfaces, low wall thicknesses and achievable tolerances are further advantages of die casting machines. At Surplex, the used machinery expert, you will find used machines from leading manufacturers such as BÜHLER, IDRA, FRECH or ITALPRESSE.

Die casting machines are used for the efficient mass production of metal products. Pressure die casting is a technique known for being quick and direct, and its main advantage is the fact that the product can be manufactured in only two steps. From liquid metal up to the end product, the only two steps necessary are the transport and production. The products processed using a die casting machine usually have high levels of dimensional accuracy and even surfaces, but because of their fine-grained inner structure and the material used, they are not set up to withstand highly static or dynamic power. An exception to this is the production of aluminium wheels through the process of aluminium die casting. Through special designs and the strength of the thick-walled material, they can take up the cross and shear force through acceleration and cornering. Nevertheless, the mechanical pressure die casting is still performed afterwards, in order to increase their mechanical properties.

Pressure die casting is a particularly efficient process, especially in relation to products made from steel, which first have to be cast, ground, cut, and stamped before they can be reformed. When it comes to its application, one of the disadvantages is the fact that there is a restricted mechanical capacity and a restricted choice of materials that can be processed with die casting machines. Only materials with a low melting point can be used; otherwise, a permanent mould out of steel cannot be onset. Products typically processed through a pressure die casting machine are the components of machines and motors, toys and kitchen tools. Aluminium pans are usually manufactured using the aluminium die casting machine. Due to the high melting point of steel, it cannot be processed using a pressure die casting machine.

When it comes to different types of die casting and the related metalworking machinery, one can choose between hot-chamber and cold-chamber die casting. During both processes, a liquid material is injected into a permanent steel mould. After the hardening, the mould separates and the finished product can be taken out. During hot-chamber die casting the melting chamber component of the machine is particularly close to the die casting tool. The main advantage of a hot-chamber die casting machine is its very high speed, productivity and efficiency, while the disadvantage of the hot-chamber die casting process is the high strain that the mechanical components are under during the melting process. This leads to high levels of wear and tear of used die casting machines. The hot-chamber die casting machines get very hot and should be shielded when in operation. When it comes to the cold-chamber die casting machines, there is a distinction between the refining production and die casting units. They do not heat up to the extent that a hot-chamber die casting machine does, and do not have the equivalently high production rate.

Generally, both types of die casting machines work fully automatically. Assistants can only be hired for the transportation of full containers containing the end product, and for the preparation of empty containers. But those workers should be briefed about the safety requirements for working in the vicinity of a die caster, even when conducting some simple tasks. The maintenance of a used die casting machine should only be conducted by specialists.

Well-known providers of die casting machinery are OSKAR FRECH, COLOSIO and BÜHLER AG. One can often find a quality used die casting machine manufactured by those and other well-known suppliers in our numerous industrial auctions as well as on our regular used die casting machines page. We also recommend subscribing to our newsletter in order not to miss any special offers on our used machines and any type of industrial machinery that may be of interest to you.
