Study on Packing Process of the Plastic Air Intake Manifold of Engines

Abstract:

Packing pressure directly influences quality of the plastic part. It is an important stage of plastic injection molding. This paper introduces the packing process.CAE software Moldflow provided the possibility to simulate the flow process of the plastic air intake manifold at different pressure and to predict the position of air traps. Packing pressure is determined by comparing analysis results and avoided mold adjustment and mold repairing. Analytic result shows that packing pressure at 70MPa can make the maximum injection pressure, melt flow rate, the required maximum clamp force smaller. And at that time, The air traps situation is also better. Practice proves that it is perfect of the finished sample of the plastic air intake manifold on basis of simulation.
