A Study on the Injection Flow with Viscoelastic Effect
점탄성 효과를 가진 사출 유동에 관한 연구
- Published : 2008.09.30
Abstract
In this paper, we design internal space in plunger-type low pressure vacuum injection molding machine from numerical study. And we study characteristic of viscoelastic flow for searching injection molding condition. Then the flow analysis was performed using the CAE S/W. The result shows optimal value of nozzle and hole in injection chamber. And we investigated qualitatively relationship between injection pressure and injection mass flow with variable shear rate
