When manufacturing die casting mold, generally, the casting layout design should be considered based on the relation between injection systems, casting condition, gating system, and cooling system. Also, the extent or the location of product defects will be differentiated according to the various relations of the above conditions. High-qualified products can be manufactured as those defects are controled by the proper modifications or the changes of die casting mold with the conditions.
In this research, the proper manufacturing method intensively be derived for reducing the defect of the internal porosities issues of power steering which is very complicated to achieve the mold design, and for minimizing and for guaranteeing the product quality through the analysis of the problem of casting parts and the deduction of alternative plans.
