簡介：

Injection molding visualization is the experimental method of direct
observation on the melt filling behavior in the mold cavity. By using developed
visualization system, the influence of mold structure design on the injection molding
product’s defects, such as jetting and weld were studied in this paper. The forming
process of jetting was observed by the visual method, and results show that it is useful
to avoid jetting by locating gate correctly. According to the generation of weld line in
single gate cavity, an improved measure to adjust the weld locations by adding
overflow traps was proposed. The result indicates that the overflow trap is good for
adjusting weld location and makes the defects appear in the unimportant points of
surface. Another experiment on the forming process of weld line in two-gate cavity
with setting different distance parameters were carried out. The result shows that
increasing of gates distance may significantly affect the performance of weld line.
