Abstract

Determination of optimal injection moulding parameters has significant impact on properties of a part. Usage of recycled material in process of injection moulding reduces costs of manufacturing but also alters properties of the part. This paper shows manufacturing process of test samples according to design of experiment, measuring of samples and statistic analysis of results in software Minitab. During trials influence of mould cavity wall temperature and content of recycled material on shrinkage will be investigated and analyzed. Content of recycled material that can be used for production of polymer part has direct influence on costs of production and the goal is to use maximal possible content of recycled material without affecting the shrinkage, respectively dimensions of part. Mathematical model that predicts final dimension of part in regard to input parameters will be set.
