介绍吹塑模内贴标的成型原理和成型工艺,提出贴标过程中出现气泡是影响质量合格率的主要原因。并着重对吹塑模内贴标成型工艺中产生气泡的因素进行探讨,给出相关问题的改善措施和正常生产所使用的工艺参数。对在模内贴标时出现气泡的桶给出新的可行的修复方法。 Introducing the molding principle and forming process of the blow mold in-mold labeling, it is proposed that the appearance of bubbles in the labeling process is the main reason that affects the passing rate of quality. The emphases are put on the factors that cause bubbles in the blow molding process, the corrective measures are given and the process parameters used in normal production are given. A new and viable solution to the barrel that bubbles when it is in-mold labeling.
