Abstract

Thermoforming process is one of the most used processes in both automotive and packaging industry. In this study, thickness distributions of Polyvinyl chloride (PVC) sheets were determined after plug assisted thermoforming. By increasing the diameter of the plug and the plug depth inside the female mould, a series of thermoforming operation were performed and plug assisted thermoformed samples were obtained. Thickness distribution in thermoformed samples was examined comparatively using graphical method. It has been found that increasing the diameter of plug and the plug depth, changes thickness distribution particularly in the side wall and bottom of thermoformed semi-finished samples.

Özet

Isıl şekillendirme prosesi, gerek otomotiv gerekse ambalaj sanayiinde en çok kullanılan proseslerden biridir. Bu çalışmada, Polivinil klorür (PVC) filmlerin, erkek kalıpla ısıl şekillendirme sonrası kalınlık dağılımları belirlenmiştir. Erkek kalıbın çapı ve erkek kalıbın dişi kalıp içerisindeki dalma derinliği artırılarak bir dizi ısıl şekillendirme işlemi yapılmış ve numuneler elde edilmiştir. Bu numunelerdeki kalınlık dağılımı karşılaştırmalı olarak grafik yöntemle incelenmiştir. Erkek kalıp çapının ve erkek kalıbın dişi kalıp içerisindeki dalma derinliğinin artırılmasının ısıl şekillendirilen yarı mamullerde özellikle yan duvar ve taban kalınlık dağılımını değiştirdiği tespit edilmiştir.
