Excessive impurities in die castings can lead to several issues such as reduced strength, brittleness, surface defects, and reduced machinability. These impurities can enter the casting process from several sources such as the die itself, the melting process, or even the alloys used. Therefore, controlling the quality of the raw materials, optimizing the melting process, and ensuring proper maintenance of the dies are critical in reducing the impurities and producing high-quality die castings. Reasons For Excessive Impurities In Die Castings Excessive impurities in die casting......

It is believed that many manufacturers should find that die-cast aluminum is not suitable for anodizing when conducting surface treatment on various series of aluminum materials. This is determined by the composition of die-cast aluminum and the characteristics of anodizing, so how is die-cast aluminum not suitable for anodizing? First of all, anodizing requires that the aluminum surface be free of impurities, and the aluminum material is relatively pure, because the anodizing film must be uniform and flat. The presence of excessive impurities and other components will inevitably......
