Aluminum suitable for die casting process is die-casting aluminum, usually die-casting aluminum alloy. It has a set of core pulling  cooling system with high technical content. Generally speaking, the materials are sent to the cavity to be cast through a centralized entrance to form parts. Casting is a process of metal smelting, which usually uses the gravity of metal to cast in the mold. But "aluminum die casting" is  done by gravity, but by a certain amount of pressure. It's a bit like "injection molding.".

High pressure  high speed filling die casting aluminum mold are two characteristics of die casting aluminum. The commonly used pressure injection specific pressure is  thousands to tens of thousands of kPa, even up to 2 × 105kpa. The filling speed is about 10 ~ 50M / s, sometimes even more than 100m / s. Filling time is very short, generally in the range of 0.01 ~ 0.2S. Its advantages include:

1. Good product quality: Castings with high dimensional accuracy are generally equivalent to grade 6-7,  even up to grade 4; with good surface finish, they are generally equivalent to grade 5-8; with high strength  hardness, the strength is generally 25-30% higher than that of sand casting, but the elongation is reduced by about 70%; with stable size  good interchangeability; castings with thin-walled  complex diecasting aluminum.

2. High production efficiency: high machine productivity, for example, the domestic J Ⅲ 3 horizontal cold air die casting aluminum machine can die cast aluminum 600-700 times in eight hours on average,  the small hot chamber die casting aluminum machine can die cast aluminum 3000-7000 times in eight hours on average; the die-casting aluminum mold has a long life, a pair of die-casting aluminum mold, die-casting aluminum bell alloy, the life can reach hundreds of thousands of times, even millions of times; it is easy to realize mechanization  automation.

3. Good economic effect: due to the accurate size of die-casting aluminum, the surface is bright  clean. Generally, it is no longer used for machining,  the processing amount is very small, so it  only improves the metal utilization rate, but also reduces a large number of processing equipment  working hours; the casting price is cheap; it can use combined die-casting aluminum to other metal  non-metal materials. It can save both assembly time  metal.
