運用田口方法決定最佳化PE淋膜機製程參數

淋膜機為製造紙材與PE複合製程重要的關鍵過程，且具有大量製造、低成本及生產快速等優點，應用層面非常廣泛，舉凡黏膠標籤、紙杯、餐盒、餐盤等。在進行PE淋膜時，為獲得最佳PE淋膜的品質，除了良好的設備及淋膜塗頭機構輔助外，尚須考慮適當的製程參數。傳統上，大多依靠比較有經驗之技術能力人員，利用不斷測試及錯誤中修正找尋方法來訂出較佳的參數組合，但此方式通常需耗費較多的時間與損耗，尤其如果進行全因子全水準實驗時更是大量損失公司試驗成本。本研究以PE淋膜機成型產品為實驗對象，應用田口方法進行實驗，找出最佳化參數製程參數。本研究選定4個實驗可控因子，分別為加熱溫度、電暈時間、冷卻時間、速度。結果顯示整體製程能力由原先的Cpk指標0.34提升到1. 45。整個PE淋膜翹曲規格收斂且穩定的狀況。關鍵字：PE聚乙烯、淋膜機、田口方法、製程能力指標。

Abstract Laminating machine is an important key process equipment for the manufacture of paper and PE composite which has the advantages of fast production, large production volume, and low cost. It also has very wide range of applications, such as viscose labels, paper cups, paper boxes, and paper plates, etc. In order to obtain the best PE lamination quality during the PE lamination process, it is not only necessary to have good laminating equipment and coating head agencies, but also necessary to consider the appropriate setting of process parameters. Traditionally, the setting of process parameters is relied mostly on experienced technicians who use trial and error method to perform this task. However, this method usually consumes more time and money, especially when it comes to full-factor and full-level experiment. In this study, the Taguchi method is applied to find the optimal parameters for PE laminating process. Four experimental controllable factors are selected, namely heating temperature, corona time, cooling time, and speed. The results of this study show that the overall process capability index (Cpk) has been improved from 0.34 to 1.45, and the entire material camber condition is convergent and stable.
