Die casting is the method used for forcing molten metal into mold cavities under high pressure. Die casting is very versatile and hence, is the widest used method for casting a metal. Die casting is same as permanent mold casting the only difference is that the metal is injected into the mould at very high pressure of 10-210 Mpa. This results in a more uniform part, usually good dimensional accuracy and also good surface finish.
The different metals and alloys that can be used in die casting are zinc, aluminum, copper, magnesium, tin and lead. Ferrous metals can also be used for die casting, die casting method is generally used for applications in which a large quantity is medium or small sized parts are required with detail, good dimension and fine surface finish.
An aluminium alloy die casting system provides a die casting machine which has a gate for melted aluminium alloys passage, sets a flow rate of melted aluminium alloy in range of 5m/sec to 15m/sec and press injects melted alloy in cavity of die. By this system it is possible to get a weldable casting having no air. An aluminium auto part manufactured by above mentioned process is weldable and also dense in structure. The result is auto parts formed of die-cast products are produced on a large scale cost effectively. Automotive Components
Aluminium and aluminium alloys casting problems: Aluminium castings have played significant role in development of aluminium industry since its inception in late 19th century. The first aluminium products were castings such as utensils and decorative parts which exploited the novelty and utilization of new discovery. Those early parts quickly expanded to meet the requirements of a wide range of engineering specifications. Die casting aluminum radiator cnc machining
