Injection molding is one of the most common and effective manufacturing processes used to produce plastic products and impacts industries around the world. However, injection molding is a complex process that requires careful consideration of several key control variables. These variables and how they are utilized greatly affect the resulting polymer parts of any molding operation. The bounds of the acceptable values of each Control Process Variable (CPV) must be analyzed and delimited to ensure manufacturing success and produce injected molded parts efficiently and effectively. One such method by which the key CPVs of an injection molding operation can be delimited is through the development of a process window. Once developed, operating CPVs at values inside the boundaries of the window or region will allow for the consistent production of parts that comply with the desired Performance Measures (PM), promoting a stable manufacturing process. This work proposes a novel approach to experimentally developing process windows and illustrates the methodology with a specific molding operation. A semicrystalline material was selected as it is more sensitive to process conditions than amorphous materials.
注塑成型是用于生产塑料制品的最常见且有效的制造工艺之一，对全球各行业都有影响。然而，注塑成型是一个复杂的过程，需要仔细考虑几个关键控制变量。这些变量及其使用方式会极大地影响任何成型操作最终得到的聚合物部件。必须分析并界定每个控制过程变量（CPV）的可接受值范围，以确保制造成功，并高效且有效地生产注塑部件。确定注塑成型操作关键CPV的一种方法是通过开发工艺窗口。一旦开发出来，在窗口或区域边界内的值下操作CPV将能够始终如一地生产符合所需性能指标（PM）的部件，从而促进稳定的制造过程。这项工作提出了一种通过实验开发工艺窗口的新方法，并用一个具体的成型操作来说明该方法。选择了一种半结晶材料，因为它比非晶材料对工艺条件更敏感。
