Description

technical field [0001] The present invention relates to a visual monitoring system for fluid filling flow process, in particular to a visual polymer melt filling flow system for injection molding process, which can be used for quantitative observation of polymer melt flow behavior and melt flow behavior during injection molding filling process. The law of migration and movement of heterogeneous solid particles. Background technique [0002] The polymer melt filling process is an important stage of the injection molding process. The melt flow state during the filling process directly affects the orientation of the polymer polymer chain, the crystallization behavior of the melt, the orientation and distribution of heterogeneous particles in the melt, etc. Thus affecting the microstructure of the polymer plastic and the mechanical properties of the final shaped product. In addition, the instability of the filling process can easily lead to surface defects such as injection mar...
