‘Core back’ expansion molding is a form of injection molding. Once the foamed resin has filled up the mold, the volume of the mold is increased, causing the foam to expand. This means larger plastic parts, with low density and good rigidity, can be made from the same volume of plastic resin. http://www.mazda.com/publicity/release/2008/200809/080909c.html
