The sandwich injection molding process leads to a nearly symmetric skin-core-structure consisting of the two outer skin layers and the inner core layer. Usually the skin material is injected with one injection unit followed by injecting the core material with a second injection unit. The monosandwich injection molding process is a new sandwich-molding technique using only one injection unit for injecting both skin and core material in one step. In this work the influence of the monosandwich injection parameters and the part geometry is experimentally analyzed using a conductive filled polyethersulfone (PES) as skin material and unfilled PES as core material. The aim for using this material combination is to establish high-temperature resistant thermoplastic parts with an antielectrostatic surface suitable for application in the production of electronic parts.
