Mould Wall Thickness Directly Affects Aluminum Die-Casting Quality

Casting wall thickness is the root of die casting quality: walls that are too thin cause short shots and tearing, while excessively thick walls lead to shrinkage cavities and depressions; sudden changes in wall thickness result in porosity and deformation. The design of mould cooling, gating, and venting systems must be precisely matched to the wall thickness distribution to ensure consistent surface appearance, air tightness, dimensional accuracy, and mould service life.
