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.

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.
