[摘要] 本文介绍了一种在工业环境中应用实验设计（DOE）方法的方法，用于识别影响空调组件塑料注塑成型过程的临界因素。关注的关键质量（CTQ）是减少工艺缺陷，即短射。采用全因子设计同时研究了五种注塑成型工艺参数的影响。这五个工艺参数是背压、螺杆转速、矛温度、歧管温度和保压传递。最后，发现了影响短射缺陷的重要工艺参数。使用回归分析建立了CTQ与重要工艺参数之间的经验关系。

[Abstract] This paper illustrates an application of design of experimental (DOE) approach in an

industrial setting for identifying the critical factors affecting a plastic injection molding process of acertain component for aircond assembly. A critical to quality (CTQ) of interest is reducing process defects, namely short-shot. A full factorial design was employed to study simultaneously the effect of five injection molding process parameters. The five process parameters are backpressure, screw rotation speed, spear temperature, manifold temperature, and holding pressure transfer. Finally, the significant process parameters influencing the short-shot defect have been found. Empirical relationship between CTQ and the significant process parameters were formulated using regression analysis.
