aluminium heat sink extrusion.Reduce the failure of die-casting molds

　　Die casting molds are essential tools for producing die castings, and they are the place where the die castings are poured and formed. A normal die casting mold is usually priced at around 10000 yuan, and some special ones can reach 20000 to 30000 yuan. This is one of the reasons for the high cost of die casting production. In order to reduce costs, it is necessary to minimize the failure of die casting molds.

　　There are many factors that can lead to the failure of die-casting molds, including external factors such as high or low casting temperature, type and composition of casting material Fe, whether the tonnage of the die-casting machine matches, casting size and shape, excessive die-casting pressure, too fast inner gate speed, wall thickness, and so on; There are also internal factors, such as the forging process of raw materials, the quality of the material of the die casting mold itself, the rationality of the mold structure design, the rationality of the pouring system design, the heat treatment process of the mold, including various requirements for fitting accuracy and smoothness.
