Analyzing the warpage in the injection molding using SLS tool inserts

Around one third of all plastics are processed by injection molding, therefore economy and manufacture 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 differences and the advantages of these tool inserts in injection molding. The main difference between the conventional tools and SLS tool insert is also described in this paper. Beyond all question, the rapid tool inserts cause different properties such as different warpage of the polymeric part.
