The industry demand for improved material properties and performance, as well as the ever increasing demand for weight and cost reduction has presented challenges for the automotive industry as a whole. From the plastic materials side, the challenge has been incorporating new fastening and assembling technology into existing applications, all while reducing cost and improving performance. This paper will explore new approaches for assembly and attachment methods for Shape Molded Expanded Polypropylene (EPP) Foam products used in automotive interiors. As EPP foam becomes more widely used throughout the automotive interior, it has become necessary to provide innovative ways of attachment and joining. Recent innovations have allowed for the insert molding of EPP using wireframes, plastic inserts, metal brackets, and bars.
