Technical difficulties of magnesium alloy die-casting raw materials
Magnesium alloy because of its light weight and high strength characteristics, commonly used in the manufacture of automotive parts, but because of its high temperature melt state instability caused by the actual industrial production of the following technical difficulties:
1. Flammable and easy to corrode
2. High process barriers
3. Charging and solidification speed
4. Defect control
5. Material properties
6. Insufficient high temperature stability
7. Difficulty in forming complex structural parts
8. The application of vacuum die-casting technology
1.Flammable and easy to corrode:
Magnesium alloy has the characteristics of easy to burn, easy to deform and easy to corrode.
This makes its production process in the process of safety production and die-casting process design put forward higher requirements.
2. High process barriers:
Magnesium alloy die casting process is complex, the technical level needs to be much higher.
For example, although semi-solid injection moulding process is more advanced, but low yield rate, expensive equipment and other problems still exist.
3. Charging and solidification speed:
Due to magnesium alloy charging speed is higher than aluminium alloy, at the same time solidification speed is faster.
This brings great challenges to the runner system and heat balance design of the mould.
4. Defect control:
Magnesium alloy in the die casting process is easy to produce porosity, inclusions and other casting defects.
These defects will affect the quality and mechanical properties of castings.
5. Material properties:
Magnesium alloy has poor plasticity, poor corrosion resistance, and there is a contradiction between strength and plasticity, it is necessary to optimise its properties through solid solution strengthening, long-range ordered phase regulation and other methods.
6. Insufficient high temperature stability:
Magnesium alloy has poor stability at high temperature, which limits its application in high temperature occasions.
7. Difficulty in forming complex structural parts:
Magnesium alloy complex structural parts are difficult to form at one time, poor dimensional accuracy, easy to casting defects.
8. The application of vacuum die-casting technology:
Vacuum die-casting technology can reduce the porosity defects, improve the metallurgical density of die casting, but its application is also facing technical difficulties.
