Abstract
A mold shim or insert is disclosed, which is placed between the surface of a forming mold or mold magnet and a fastener strip that is to be molded into a foam object. The mold shim compensates for the variability of the mold surface and provides a more even surface for the fastener strip to seal against —thereby preventing fouling of the strip's fastening elements during the molding process. Alternative embodiments of the invention are not used with a fastener strip, but instead have engaging members on their non-mold-proximate surface for engaging clips or wires which are thereby embedded into the foam object during the molding process.
