For zinc alloy die-casting, every design detail will have a huge impact on the product, so it must be implemented according to specifications. Here, take the wall thickness as an example, because it has a lot to do with the quality of die castings.
Under the condition that the zinc alloy die casting has sufficient strength and rigidity, the wall thickness should be reduced as much as possible, and the wall thickness should be kept uniform. When the wall of zinc alloy die casting is too thin, the metal welding is not good, which affects the strength of the casting and makes it difficult to form; if the wall thickness is too large or severely uneven, it is easy to shrink and crack. As the wall thickness increases, defects such as porosity and shrinkage in the casting also increase, which also reduces the strength of the casting. The wall thickness of die-casting parts is generally 2.5~4mm, and parts with a wall thickness of more than 6mm should not be die-casted.
