THE SIMULATION OF MONO-COMPONENT INJECTION PROCESS TO OBTAIN PARTS WITH ONE OR MORE GATE LOCATION

The injected thermoplastics products meet increasing by more in all activities fields. The injection process can be mono-component, bi-component and multi component. This paper presents a simulation of a mono component injection process to obtain high complexity parts. Using Moldflow software package will be reviewed the following aspects regarding: optimization of gate location number; melt-front temperature variation; filling time-variation; cooling time-variation; flow-orientation lines and warp. Material used for simulation is Polyethilene 232J and represents a landmark case won a hand tool. The purpose of this study is to highlight the differences obtained for a complex piece depending on the number of injection gates.
