Projeto de uma injetora manual de bancada para moldagem por injeção

Abstract

njection molding is one of the most used polymer processing methods in Brazil and worldwide. An injection molding machine is one that heats a thermoplastic material and injects it into a mold cavity to shape the polymer. This method is effective and profitable, especially when the production of a large number of parts is done, but the set of injection molding machine and mold may become economically unviable if the desired number of parts is low. The challenge is to develop a project of a bench injection molding machine that is economically viable, and that depends on few resources to be able to mold small batches of parts, in order to become a useful and practical tool for students and researchers at the university. In this context, this work aims to present a project, a methodology and a functional prototype to meet this proposed demand, which can perform the injection of small batches, with the most common materials, and that remains with low cost for its production, considering materials and manufacturing methods available at the UTFPR - Guarapuava Campus.
