Aluminium Casting Design Car Cold Water Plate

1. Determine the shrinkage rate and use a casting model to enlarge the size of the casting during the mold design process. The dimensions of the die casting model cavity and core obtained from this design result have taken into account the shrinkage factor. There are several methods for setting the shrinkage rate, which are flexible and practical. On the premise of ensuring that the dimensional requirements of the casting are met, the casting can choose a certain shrinkage rate to set; Different shrinkage rates can also be selected to set certain dimensions individually based on the different shrinkage resistance of the casting; It is also possible to select a shrinkage rate for certain features with similar shrinkage rates on the casting to enlarge the size of the casting model. In addition, the system can also be used to set the shrinkage rate according to a certain axis of the coordinate system, such as in the two directions perpendicular to the parting surface, and castings can often choose the axial shrinkage rate.
