3d printed injection mold.How to prevent insufficient pouring of aluminum alloy die castings

　　There are many types of defects in castings, and insufficient pouring is one of them. Insufficient pouring, also known as insufficient pouring, refers to the phenomenon where the metal liquid does not reach a certain amount due to insufficient weight or calculation errors, and cannot completely fill the casting cavity, resulting in incomplete castings. But fortunately, it is relatively easy to detect during casting inspection, so it can be easily screened. How to prevent the occurrence of insufficient watering? The first thing that comes to mind is to calculate the weight of aluminum alloy die castings, prepare sufficient liquid metal, and ensure that it smoothly fills the mold cavity. According to the reasonable design of the pouring system structure for aluminum alloy die-casting parts, it is ensured that the metal liquid can be smoothly filled during pouring. If the structural system has problems such as small cross-sectional area and long distance from the set position, the flow rate of odd numbered pages will be slow during pouring, and it will not reach the mold cavity, resulting in pouring failure.
