Design, Analysis and Verification of 4 Micro Cavities for a Standard Runner System

This paper presents the design, analysis and verification of 4 micro cavities for a standard system using a molding software package. It is essential to design a runner system which is best suited for a micro injection molding. In designing the runner system, one of those significant criterion is the ease of the micro cavity filling. The simulation and analysis through molding software package is conducted with the purpose of providing necessary data for the purpose of optimizing each and every different runner system studied in this work. Robust design is employed and orthogonal arrays as well as analysis of variance are utilized in order to obtain an optimum result in each runner system analysis. At the end, optimized runner systems were evaluated against a small number of criteria which are mainly the filling characteristic and the efficiency of the runner system.
