影响注塑成型制品质量的工艺要素有很多,模温控制只是其中之一。即使是在相对较窄的成型工艺参数中,也几乎无法数清不同变量的数量。因此,本文探讨的范围限制在三个不同类别质量问题的一些基本原因:启动过程中出现的问题、突然出现的问题和随时间形成的问题。由于热流道系统只会给本已复杂的探讨对象增加更多的变量,故假设我们只处理冷注道模具。这里还假设注塑机安装正确,冷
There are many factors affecting the quality of injection molding products, mold temperature control is just one of them. Even in the relatively narrow molding process parameters, it is almost impossible to count the number of different variables. Therefore, the scope of this article is to explore some of the basic reasons for the quality problems in three different categories: problems that arise during startup, problems that emerge, and problems that develop over time. Since the hot runner system will only add more variables to the already complex subject matter, it is assumed that we only deal with cold runner molds. It is also assumed here that the injection molding machine is installed correctly and cold
