Die casting involves fusion, which is a process in the action of passing a dense liquid under the action of heat. With this significant contribution of energy, there is a relaxation of the covalent bonding and atoms separates. For pure metals, the action is called melting point whereas for an alloy it is known as a melting interval. Different metals or alloys have different melting point or interval (silver 960 °, gold 1063 °, copper 1083 ° interval between 960 and 1083 °). During the process, energy is provided to the gas in the form of heat, the average velocity of the particles increases and thus the temperature increases.
Two types of industrial fonts
There are two types of industrial fonts for die casting. The first involves heat from flames provided by a torch., which is ignited by a gas mixture of butane, propane or acetylene and oxygen. A temperature of 3000 C may be reached. The advantage is the cost of low back especially in the purchase of equipment. The second one is, electric induction melting. This is achieved by a magnetic field created by means of a coil through which an alternating current passes which creates a magnetic field. The atoms are excited by the magnetic field, which generates heat.
Die casting alloys generate generally an eutectic during solidification. This fusion is perpendicular to the path and is directed to the exterior. The pressure and depression of the compressed air caused by the vacuum through the port of the coating produce a centrifugal force. For in-depth information contact Melbourne Gravity.
