ADC12 for aluminum alloy die casting. Aluminum alloy die casting products are mainly used in electronics, automobile, motor, home appliances some communication industries. Some high-quality aluminum alloy products with high performance, high precision high toughness are also used in large aircraft, ships other industries with high requirements.
Die casting is especially suitable for manufacturing a large number of small medium-sized castings, so die casting is widely used in various casting processes. Compared with other casting technology, the surface of die casting is more flat has higher dimensional consistency.
Die casting for short is a kind of casting method that pour molten alloy into the pressure chamber to fill the cavity of steel mould at high speed make alloy liquid solidify under pressure to form castings. The main characteristics of die casting different other casting methods are high pressure high speed.
1. The metal liquid is filled in the mold cavity under pressure crystallized solidified under higher pressure. The common pressure is 15-100mpa.
2. The filling time of liquid metal is very short, about 0.01-0.2 seconds (depending on the size of the casting), which can fill the cavity. Die casting is a kind of precision casting method. The dimension tolerance surface accuracy of die casting parts are very small. In most cases, die casting parts can be assembled applied without turning, threaded parts can also be directly cast.
