cold chamber pressure die casting.Factors affecting zinc alloy die-casting

　　Zinc alloy die-casting, as one of the most commonly used die-casting processes, maintains the interests of many people. In order to improve profits, many people are exploring how to produce better quality die-casting parts through zinc alloy die-casting. Through production and experimentation, many factors that affect zinc alloy die-casting have been summarized, such as the pouring temperature of the metal liquid, injection rate, mold temperature, cooling rate, etc. The composition of raw materials is also an important factor.

　　It is well known that the composition of zinc alloy can affect the quality of zinc alloy die-casting, but do you know that aluminum is present in zinc alloy? Do you know what role aluminum plays in zinc alloy die casting? Aluminum in zinc alloys can play two roles: A. improving the casting performance of zinc alloys, increasing alloy fluidity, refining grains, causing solid solution strengthening, and improving mechanical properties. B. Reduce the reactivity of zinc to iron and reduce erosion of iron materials such as goosenecks, molds, and crucibles. The popularity of zinc alloy die-casting is attributed to the indispensable role of aluminum.
