Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, household appliances and some communication industries. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in industries with high requirements such as large aircraft and ships.

Die casting is especially suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used in various casting processes.

Compared with other casting technologies, die casting has smoother surface and higher dimensional consistency.

Features:

Pressure casting (die casting for short) is a casting method in which molten alloy is poured into a pressure chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. The main characteristics of die casting are high pressure and high speed.

1. Molten metal fills the cavity under pressure and crystallizes and solidifies under higher pressure. Common pressure is15-100 MPa.

2. The speed of filling the cavity with molten metal is very fast, usually 10-50m/s, and some even exceed 80m/s (the linear speed of introducing the cavity through the inner gate-the speed of the inner gate), so the filling time of molten metal is extremely short, and the cavity can be filled in about 0.0 1-0.2 seconds (depending on the size of the casting).

Die casting is a precision casting method. The dimensional tolerance of die-cast parts is very small, and the surface accuracy is very high. In most cases, die-casting parts can be assembled and applied, and threaded parts can be directly cast without turning.
