The density of aluminum is about 2.7g/cm3, which is only higher than the second light metal of magnesium in the metal structure material, and only 1/3 of that of iron or copper.

In the modern production process, die casting has been a particularly common production mode, common die casting aluminum alloy die casting, zinc alloy die casting, magnesium alloy die casting, to give you a simple introduction to the principle of die casting:

First, there is a pattern on the surface of the casting and a trace of metal flow? Causes: 1, the flow channel leading to the casting inlet is too shallow; 2, the injection ratio pressure is too large, resulting in excessive metal flow rate, resulting in metal liquid splashing.

Die casting structure design is the first step of die casting work. The rationality of the design and process adaptability will affect the smooth progress of the follow-up work, such as the selection of parting surface, the opening of the inner gate, the layout of the launching mechanism, the mold structure and the difficulty of manufacturing, the rule of alloy solidification and shrinkage, the precision of the casting, the types of defects and so on, will take the advantages and disadvantages of the die casting itself as the premise.
