Investigation of Mechanical and Dimensional Features in Unfilled Polyketone Polymer

Abstract

High performance engineering polymers are widely used in automotive sector today. For this reason, the mechanical and dimensional of one of these polymer materials after injection molding under different process conditions (melt temperature, injection pressure and gate type) will be investigated. In order to examine the mentioned properties of these polymers, a series of plastic injection experiments were carried out based on the Taguchi Experimental design (L 9 ). In the experiments, tensile strength, percentage elongation and shrinkage values were obtained by using the parameters of mold temperature, injection pressure and type runner gate. At the end of the study, time and cost savings were achieved by performing the least number of experiments according to the Taguchi experimental design. In addition, the problems encountered in the use of polymer materials in the literature and industry have been tried to be removed. Moreover, some solutions will be provided on mechanical and the quality problems in plastic injection molding.
