Factors Affecting the Quality of Aluminum Shells

First of all, the aluminum case is produced under high temperature, aluminum shell production is too fast that the intensity of cooling than larger, leading to some elements cannot be in the alloy element with changing needs in the time allotted. There is a needle-like structure and hardness in the material, which is relatively high, poor ductility. And the manufacturing process has a low tensile strength, appears not only in the high temperature, yellow rust and cracks will appear.

Experience in production of aluminium have granular presence of burrs. If this burr is not cleaned up, such particles often have tadpole-shaped tails with the next. Being looked at under a microscope, the impurities present color is gray, containing a lot of iron.

Aluminum shell and some impurities can affect the function of the entire shell, and shell inside the process of aluminum. If refining is not sufficient, soil, refining agent, covering agent and powder coatings and oxide impurities are mixed with shell that would result in reduced quality of the aluminum housing.
