Sun Bao-fu, Jiang Cong, Hu Ming-jiang

ABSTRACT: Firstly, application of Moldflow on the mobile phone cover with two different injection methods which one is to use pin-point gate and the other is to use latent gate to simulate the injection molding process, then we analyze the results from the filling time, air traps, weld lines and the warpage four aspects. Lastly, we find out the effect of latent gate is better than that of pin-point gate by compare the above four results.
