塑胶产品在成型过程中披锋的工艺改善方法

Technology improvement of flash on the forming process for plastic products

披锋,塑胶行业的品质用语,指产品边缘多出的无用部分,因为多出的部分通常带有锋,所以称为披锋。披锋通常产生于模具分型面,镶件,斜顶边缘位置,主要是由材料流动性,模具结构缺陷,产品设计不合理,成型工艺不恰当造成的。目前,各行业的塑胶产品使用越来越广泛,很多产品结构设计已经由塑胶替代金属,顺应轻量化时代的需求。如:汽车产品,家电产品,电子产品,等零件。但是塑胶产品在模具成型的过程中很容易产生披锋,这对于产品质量,是致命的质量缺陷。本文以家电产品空调面板为例,研究塑胶产品在成型过程中披锋产生的原因,并研发出了对应的改善方案。不仅满足了客户对产品外观的要求,提升了产品档次,且突破创新了模具此类痛点问题的解决对策。本文从塑胶产品成型工艺参数改善披锋方面进行了阐述及原理介绍,使读者对成型工艺在模具成型中的影响有一定的认识。

Flash, The term＂the quality of the plastic industry＂, A useless part of a product＇s edge. Because the extra part usually has a frunt, So it＇s called a cape. The flash is usually produced in the mold parting surface, insert, slider position. Due to material fluidity, defect of mold structure, unreasonable product design, impruper molding process. At present, the use of plastic products in all industries more and more. Many product structure designs have been replaced by plastic. Adapt to the needs of the era of light-quantification. For example： automobile products, home appliance, electronic products, etc. However, plastic products are easy to cause flash in the process of mold forming. This is a fatal quality defect for product quality. This paper takes home appliance air conditioning panel as an example. Sludy on the cause of plastic products in flash. The corresponding improvement plan has been developed, lt＇s not only meet customers＇ requirements towards appearance and update product grade, but also make a breakthrough for such pain point of the mold. In this paper, the paper expounds and introduces the process parameter improvement of plastic products. The influence of the reader on molding process in mold forming is recognized.
