| Abstract: | The research status of weld line in injection molding was introduced. The formation mechanism of weld line
was expounded. The strength prediction studies of weld line such as prediction model and automatic recognition
algorithm were summarized. The studies of the weld-line in microcosmic view were concluded. and the influences of the
melt temperature, mold temperature and injection pressure on the weld-line were achieved. Based on the traditional
technology of the injection molding, rapid heat cycle molding which was a new injection molding technology to improve
weld line was presented. and two new kinds of optimizing mold structure were introduced as an improvement of weld line. |
