EFFECTS OF PROCESSING PARAMETERS ON OPTICAL PROPERTIES OF INJECTION MOLDED POLYSTYRENE PARTS

摘要

In this paper, PS products qualities are discussed by experiments to find the relations between processing parameters and residual stresses, optical properties. Residual stresses are measured by polarimeter. The variance of processing parameters is considered when residual stresses distribution and polarimetric interference are measured. Also the optical property of transparency and haze are measured by transmittance meter. From the experiments results, we find that processing parameters have great effects on residual stresses and haze but little effects on transparency.
