INFLUENCE OF MOLD PROPERTIES ON THE QUALITY OF INJECTION MOLDED PARTS

Around one third of all plastics are processed by injection molding, therefore its economy and manufacturing technology have fundamental importance. The major issues in the development of injection molding tools include the progress in material technology and the developments in tool design methodology, such as developing rapid tool inserts. It is essential to develop fast methods to manufacture tools for injection-molded-like prototype parts or mass-produced parts. Due to these high requirements, it is more and more significant to use simulation methods to optimize the part before manufacturing. This paper shows the advantages of tool inserts in injection molding. The main difference between the conventional injection molding tools and rapid tool insert is also described in this paper. Beyond all questions, the rapid tool inserts cause different properties such as different warpage of the polymeric part
