Magnesium alloy has a wide range of uses. It can be used in many fields such as aerospace, medical, electronic products, etc. It can be described as an indispensable "essential oil" in many industries ". The magnesium alloy die-casting can be said to be one of the most important application technology, magnesium alloy die-casting process is similar to other die-casting process, but because of the different characteristics of magnesium alloy, there are different places in the pressure, speed, temperature and coating application.

Magnesium alloy die-casting hot chamber and cold chamber two, die-casting pressure is also different. The shot pressure of the hot chamber machine is about 40MPa, while the specific pressure of the cold chamber machine is usually 40-70MPa. Magnesium alloys have low inertia due to their low density. At the same time, due to the rapid solidification of magnesium alloy, it is necessary to fill the entire cavity before the metal solidifies, so the injection speed of magnesium alloy is faster. In addition, temperature is a thermal factor in the process of magnesium alloy die casting. In order to provide good filling conditions, ensure the quality of die casting, control and maintain thermal stability, corresponding temperature specifications must be selected, mainly refers to the mold temperature of the pouring temperature of magnesium alloy. The role of the coating is to provide an effective isolation layer between the die-casting alloy and the mold to prevent the molten metal from directly flushing the cavity.
