Boss Design and Optimization for Microcellular Foam Injection Molded Parts

摘要

There are two basic models companies following when implementing the MuCell ® microcellular foam injection molding process. The first and most common implementation is to apply the technology to a part designed for solid. The second implementation involves parts designed specifically to optimize performance with the microcellular foam process. In either case, the customer needs to understand the expected performance of the fastening mechanism. This study identifies the achieveable fastening performance with screws when using boss designs for standard solid injection molding and also identifies the optimum design geometry for microcellular foam molded boss design.
