以往的窗簾葉片主要是用鋁或鐵製薄片經過加工製成弧形截面後,再經表面烤漆而成,但是這種傳統葉片具有原料成本高、成品重量重及容易吸熱而導致隔熱效果差等缺點。為了改善上述問題,有業者開發出利用像是聚氯乙烯發泡材料之類的塑膠原料所製成的葉片,以達到降低成本、輕量化及隔熱效果佳等目的。但是目前用來製造聚氯乙烯發泡材料葉片的成型模具主要採用一進一出的設計,也就是只有一個入料口與一個出料口,如此將會導致生產效率低落的問題。 In the past, curtain blades were mainly made of aluminum or iron thin slices that were processed into an arc-shaped section and then painted on the surface. However, such traditional blades have high raw material costs, heavy finished products, and easy heat absorption, resulting in poor heat insulation. And other shortcomings. In order to improve the above-mentioned problems, some companies have developed blades made of plastic materials such as polyvinyl chloride foam materials to achieve cost reduction, weight reduction, and good thermal insulation effects. However, the current molding dies used to manufacture PVC foam material blades mainly adopt a one-in-one-out design, that is, there is only one inlet and one outlet, which will lead to the problem of low production efficiency.
