The effect of process parameters on thickness distribution in thermoforming

Ekşi O., Karabeyoğlu S. S.

Advances in Science and Technology. Research Journal

Vol. 11, no 2

198--204

In this study, cylindrical, conical and hemispherical molds were used to form flat thermoplastic sheets which are 1.5 mm in thickness. The effect of plug assist on thickness distribution was investigated. The sheets were formed with and without plug assist. Then thickness distributions on thermoformed products were obtained for two experimental procedures by a digital caliper (Resolution: 0.01 mm). As a result, plug assist thermoforming provides more uniform thickness distributions than negative forming.

An experimental study on wall thickness distribution in thermoforming

In this work, Polystyrene (PS) sheets were thermoformed in predetermined conditions. Wall thickness distributions obtained by experimental method in PS thermoformed products. Then the same thickness distributions were predicted by using Geometric Element Analysis (GEA). The thickness results were obtained experimentally, compared to thickness distributions which were predicted by GEA. It has been found that GEA does not precisely reveal thickness distributions.
