一个成功的热流道模具应用项目需要多个环节予以保障,其中最重要的有两个技术因素:一是塑料温度的控制;二是塑料流动的控制。1.塑料温度的控制在热流道模具应用中塑料温度的控制极为重要,许多生产过程中出现的加工及产品质量问题直接来源于热流道系统温度控制的不好,如使用热针式浇口方法注塑成型时产品浇口质量差问题, A successful hot runner mold application projects need to be protected in several aspects, the most important of which are two technical factors: First, the plastic temperature control; the second is plastic flow control. 1. Plastic Temperature Control In the hot runner mold plastic temperature control is extremely important, many of the production process appears in the quality and product quality directly from the hot runner system temperature control is not good, such as the use of hot-pin gate method Injection molding product gate poor quality problems,
