MOLDAGEM DE ELASTÔMEROS EPDM: otimização do tempo de cura

Abstract

The use of thermosets is very broad and, in all industries, are used in large scale constitute the most important group among all non-metallic materials. Each day synthetic materials are replacing traditional materials such as steel, aluminum and even wood and fabric, and besides being more economical in many cases retain the mechanical efficiency of other materials. For the need of increased production of parts produced in injection molds, this study aims to discuss a method of adjusting the parameters of injection molding compound in order to reduce the healing time in the process of injection molding elastomeric ethylene-propylene-diene monomer (EPDM) with the intention of increasing the productivity of injection molding processes in series production. By using a linear model graphical representations were obtained, which was possible to predict the characteristics of the molded composite within a range in injection molding parameters investigated.
