What are the factors that affect the quality of die-casting parts

　　1、 Die-casting machine

　　The die-casting machine is the basic key to die-casting production. Before designing the die-casting mold, we need to choose the die-casting machine based on the size, volume, and process structure characteristics of the die-casting parts. In order to ensure the good performance of the die-casting machine, it is also necessary to regularly inspect the die-casting machine, identify various problems and promptly handle them.

　　2、 Die casting structure

　　The rationality of the structure of die-casting parts has a direct impact on the structure of die-casting molds, the quality of die-casting parts, and production costs. If the structural design of the die-casting parts is not reasonable, the shifting of the mold will not only lead to the complexity of the die-casting mold structure, but also the quality of the forming cannot be guaranteed.

　　3、 Die casting process parameters

　　In the process of die-casting production, these process elements affect and constrain each other. Only by selecting and adjusting these elements reasonably and coordinating them consistently can satisfactory results be achieved and the quality of die-casting parts be improved.

　　Reasons for Bubbles in Zinc Alloy Die Castings

　　The zinc alloy die-casting parts have the advantages of smooth surface, wear resistance, and high precision. The most common defect in the production process of zinc alloy die-casting is the formation of bubbles on the surface of the castings. So, what is the reason for the appearance of bubbles on the surface of zinc alloy die-casting parts?

　　1. If there is too much release agent or mold oil and water, and the design of the mold has too small or too few air pockets, the gas produced by the release agent cannot be eliminated when high-temperature zinc alloy slurry is injected into the mold, resulting in foaming on the product.

　　2. The pressure adjustment of the die-casting machine is not large enough, making it difficult to remove gas from the mold.

　　3. It's because the nozzle is broken or not aligned properly.

　　The hammer in the furnace is broken.
