Optimization of Gating System and Minimization of Casting Defect based on Casting Simulation: A Review

Abstract

Investment casting process is a manufacturing process to make complex geometrical parts of metal materials in mass production. But many times different defect occurs such as shrinkage cavity or porosity. These defects can be minimized by appropriate changes in gating parameters, such as gating system location, shape and size. Improving the casting gating systems based on design principle of gating system and casting simulation with the goal of improving casting quality such as reducing casting defects and increasing yield.
