Effects of melt and mold temperature on mechanical properties of injection molded part

Injection molding is one of the most common processes used to produce plastic parts. It is a cyclic process of rapid mold filling followed by cooling and ejection. A variety of materials both plastic and non-plastic can be used as feedstock. However, the machine must be configured for the type of material used. The properties of an injection molded part depend upon the working material and upon the processing parameters as injection pressure, holding pressure, melting temperature, injection speed etc. As part of the paper, the samples of polypropylene were made by adjusting various parameters (melt temperature, mold temperature). Afterward, the tensile properties of obtained specimens were analyzed. The mathematical models that show dependence of tensile properties on the injection molding parameters were obtained as the result of analysis.
