Abstract:
The dist ribut ions of pressure and temperature play an important ro le in inject io n molding . T he accurate predict ion o f the dist ribut ion is one of key techniques in inject io n molding . With bet ter understanding o f the principle of flowing process and the viscoelast ic stress theory , the pressure equat ion and the temperatur e equat ion for the f low ing po lyester w er e put forw ard in this paper . And a new numerical method called the Finite Analyt ic Method fo r so lving part ial dif ferential equat io ns is employed in f low simulat ion of inject ion mo lding. Filling a mult iple-g ated rectang ular cavity is simulated in this paper . The simulat io n result agrees w ith the result from literature. It proves that the equatio ns and f inite analyt ic solut io n are right .
