Some of the variables that have an impact on the mold life of aluminum die casting include the following from sdfbcx's blog

When it comes to aluminum die casting molds, there cannot be enough emphasis placed on the importance of the materials used in the process.

You should pay close attention to the deformation and cracking that occurs as a result of the poor structural engineering when it is subjected to the subsequent heat treatment. In order to prevent heat treatment deformation and cracking during the heat treatment process, a cross-section size that is uniform, symmetrical, and simple is required. Technology advances at an accelerating pace, and it is becoming increasingly important to pay close attention to the application of advanced processing technology, which is conducive to improving the machining accuracy of mold parts while simultaneously extending the service life of the mold. With the advancement of technology, advanced processing technology is becoming increasingly important..

The Influence of Grinding and Electrodeposition on the Performance of an aluminum die casting Mold
The amount of time spent grinding can cause the metal surface to become overheated in some areas, resulting in high surface residual stress and structural changes, which can lead to grinding cracks. Grindability cracks can be caused by a variety of factors, including insufficient tempering, improper pretreatment of the original structure, carbide segregation, coarse grains, and other variables. Quenching occurs when the amount of stress applied exceeds the strength limit of the component. Quenching means that the component is weakened in some way.

It is critical to avoid selecting an injection speed for the aluminum dies casting mold that is too fast for the application when determining the injection speed of the mold.
