(Summary description)Aluminum die-casting mold is used in industrial production to obtain various molds and tools for required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping, stretching and other methods. Aluminum die-casting mold processing is composed of different parts. What characteristics should the parts have?  
1. The wear resistance of parts is one of the basic and important properties of aluminum die-casting die processing, because there is severe friction between the cavity surface and the blank during aluminum die-casting die processing, which leads to the failure of aluminum die-casting die due to wear.
2. The parts shall have high temperature resistance. When the aluminum die-casting die is processed, the temperature is higher, and the convergence hardness and strength are reduced, resulting in early wear or plastic deformation and failure of the aluminum die-casting die.
3. The parts shall have cold and hot fatigue resistance. The aluminum die-casting die is in the state of repeated heating and cooling during the working process, which makes the surface of the cavity subject to tension and pressure strain stress, causing surface cracking and spalling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy, resulting in the failure of the aluminum die-casting die.
4. The parts shall have corrosion resistance. When the aluminum die-casting mold such as plastic mold is working, due to the presence of chlorine, fluorine and other elements in the plastic, HCI, HF and other strong corrosive gases are decomposed after heating, which erode the surface of the aluminum die-casting mold cavity, increase its surface roughness, and intensify wear failure.
