Measurement of Tensile Strength on Engineering Polymers Used in Plastic Rail Terminal Parts

Abstract

Engineering polymers are of great importance in plastic rail terminals used in electrical panels in many sectors. Polyamide is fatigue resistant with a low coefficient of friction and has high tensile strength, is the most important of these polymers. In this study, the mechanical properties of engineering polymers used in the production of these terminals under different ambient conditions will be investigated. Tensile test specimens were obtained by plastic injection molding to determine the optimum injection parameters for these properties. A plastic injection machine (Arburg) and metal mold were been conducted to plastic experiments. Taguchi L8Experimental design was used to examine the parameters of cooling time, injection speed, mold temperature and runner type. From this study, it can be seen that runner gate way is most effective parameters among four parameters. As a result, the effect of runner gate ways used in plastic injection molds on tensile strength was investigated.
