Influence of Injection Moulding Parameters on Tensile Strength of Injection Moulded Part

Abstract

Polymeric materials processing is one of the fastest growing industries in the world. One of the most important method for processing polymeric materials is injection molding. 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 polyamide were made by adjusting various parameters (injection pressure, injection speed). Afterward, the tensile properties of obtained specimens were analysed. The mathematical models that show dependence of tensile properties on the injection molding parameters were obtained as the result of analysis.
