In recent years, the total production of Die Casting Part in China has steadily increased, and the industry has developed rapidly. This is mainly due to the continuous information on Chinese casting orders, and the Chinese casting industry gradually gaining recognition and praise from overseas companies. With the development trend of the global Aluminum Alloy Die-Casting industry, its production and processing focus is gradually shifting to China. Driven by the trend of global economic integration, the demand for die castings is constantly increasing in various aspects. In addition, China has unparalleled human resources and aluminum location advantages, which immediately promoted a significant increase in the total production of Aluminum Alloy Die casting. We all know that die castings are widely used, especially in the mechanical manufacturing industry, where there is a particularly high demand for die castings. In recent years, the development of China's automotive industry has become rapid, and the demand for die castings has steadily increased, greatly promoting the development trend of China's die casting industry.
Do you know the methods to prevent casting defects and drawbacks of aluminum alloys? Below, everyone will discuss for you;
1. The casting structure should be established in a reasonable and uniform manner to reduce hot spots.
2. For castings with uneven thickness, a thicker part should be placed in a larger area on top, which is beneficial for adding a riser.
3. The amount of cast iron can be appropriately increased.
4. Properly select the pouring position and pouring system to cause additional or sequential condensation. The compactness of the sand mold should be appropriate.
5. Ensure the sequential solidification of castings and pull casting defects and defects into the riser. Therefore, it is advisable to choose the position of the casting during pouring as effectively as possible; Using raw materials with different thermal conductivity coefficients in each part of the casting mold, a straight runner is placed to control the thermal conductivity speed of various parts of the casting, resulting in a standardized sequence of condensation towards the riser direction.
6. The metal casting effect of expanding the riser. Place a sufficient number of steel grade risers in appropriate locations to ensure sufficient liquid metal, and adhere to the principle of metal casting for castings.
7. Choose and manipulate the composition of the metal material liquid to avoid shrinkage of shape memory alloys as much as possible.
8. Properly selecting the pouring environment temperature and pouring speed can reduce the pouring environment temperature and pouring speed without improving other defects.
