Understand The Structural Design Of Zinc Die Casting

Update:20 May 2022

For zinc die casting , the first step of the work is the design of the structure. The rationality of the design and the adaptability of the process will affect the smooth progress of the subsequent work, such as the selection of parting surface and the types of defects, etc., will be based on the pros and cons of the die casting itself. Today we talk about wall thickness.

The wall thickness of die castings is related to performance; the wall thickness of die castings affects the state of molten metal filling the cavity, and ultimately affects the surface quality of the castings; the wall thickness of die castings affects the consumption and cost of metal materials.

When designing die-casting parts, to ensure the reliability of strength and rigidity, the thicker the wall, the better the performance; for die-casting parts, as the wall thickness increases, the mechanical properties decrease significantly. On the contrary, the crystal grains of the center layer of thick-walled die-casting parts are relatively large, which tends to produce defects such as internal shrinkage cavities, pores, and depressions on the outer surface, so that the mechanical properties of the die-casting parts decrease as the wall thickness increases.

Of course, the structural design of lead die casting is also very important.
