Abstract

This paper describes algorithms for automated design of rotary-platen type of multi-shot molds for manufacturing multi-material objects. The approach behind our algorithms works in the following manner. First, we classify the given multi-material object into several basic types based on the relationships among different components in the object. For every basic type, we find a molding sequence based on the precedence constraints resulting due to accessibility and disassembly requirements. Then, starting from the last mold stage, we generate the mold pieces for every mold stage. We expect that algorithms described in this paper will provide the necessary foundations for automating the design of rotary-platen molds.
