【Abstract】 The principle and characteristics of valve-typed injection control are introduced. Through the study on filling mode controlled by injection system, based theoretically on injection flow, and by CAE technology, the filling process is simulated. The relations between gate position and injection pressure, weldline as well as part thickness in valve-typed controlled filling process are analyzed. It’s a theoretical reference to improve injection processing conditions and the quality of injection products.更多还原
