Abstract
The aim of this work was to evaluate the effect of shear plastic into the mold cavity with a variable height on the structure and selected properties of molded parts. It was used as a special designed mold for producing test samples with varying thickness. It was shown, that the wall thickness of the molded part can significantly affect its properties, not only because of the greater volume of the amount of material, but also because of the process taking place within the the molded part during the solidification of the material. The degree of crystallinity can be different depending on the cooling time, which may contributes to the change in strength.
