Design and optimization for gating system of bearing base molding

In this paper, the best gate location of the thin-walled part bearing base was chosen by using Moldflow software. Two types of gating systems, namely, point gate and disk-shaped gate were designed. By comparing with the analysis of filling, tempe rapture at flow front, volume shrinkage and weld lines of two different gating systems, the better gating system is determined. Type of gate is disk-shaped gate, which provides the basis for the entire mold design. Simulation method improves not only the efficiency of testing mold, but also quality of product.
