Abstract

A hollow article such as an active bolster for an automobile is formed of an injection molded panel having a ridge and furrow adjacent a panel perimeter and an injection molded sheet having a bonding section at a sheet outer periphery, wherein the bonding section is within the furrow. An injection molded bond is formed between the bonding section and furrow, wherein a compression area where the sheet overlies a region of the panel adjacent the furrow is configured to constrain the bond to the furrow. An associated process and system facilitates mold alignment, part alignment, material strength, design adaptability, efficient processing, reduced labor, increased production rates, reduced energy consumption per part, aesthetically pleasing surfaces, and reduces or eliminates the need for a separate welding operation.
