　　Frequent occurrence of adhesive film in aluminum alloy die-casting production

　　Due to the fact that aluminum alloy die-casting production requires working at around 500 degrees Celsius, in addition to being subjected to high pressure, it also has to withstand high temperature effects. So, in the production of aluminum alloy die-casting, the phenomenon of mucous membrane often occurs. So, how should aluminum alloy die-casting factories deal with the frequent mucous membrane of aluminum alloy die-casting parts?

　　In fact, the phenomenon of aluminum alloy die-casting film is a very common phenomenon in die-casting production. To control the occurrence of film phenomenon in aluminum alloy die-casting parts, it is necessary to find the corresponding reasons for analysis. However, through years of experience accumulation, we have summarized the following points:

　　1. The temperature adjustment of the die-casting mold is too high, exceeding the required range.

　　2. Insufficient demolding slope, resulting in mucous membrane due to being too small.

　　3. The polishing of the die-casting mold is not in place.

　　4. The release agent is not sprayed properly.

　　5. The issue of aluminum alloy raw materials.

　　6. Unreasonable flow channel design can also cause the phenomenon of adhesive film in die-casting molds.

　　Based on the analysis of the causes of the mucosal phenomenon mentioned above, the following solutions are summarized:

　　1. Firstly, check the mold temperature and combine it with the previous production plan to see if there is any situation of excessive temperature.

　　2. Check the ratio and usage of the release agent to see if it meets production requirements.

　　3. Improve the pouring system and cooling system of the mold.

　　4. Improve the parameters of the pressing process and modify them appropriately.
