Material, Machine & Process Innovations Give Birth to SRIM Truck Box

摘要

Automotive use of high-density structural RIM (HD-SRIM) technology has progressed from its beginnings in bumper beams to full-size pickup-truck boxes and tailgates. Improved polyurethane chemistry, robotic preforming technology,and refinementsof molding tecchnique all helped make possible commercial production of these large, complex structural parts. Here, for the first time, are the details on the technical developments behind this project.
