<p>A process is disclosed for rapidly molding articles from foamable beads comprising pre-expanding foamable beads containing an excess of a foaming agent with heat under conditions to form pre-expanded beads. The pre-expanded beads may contain sufficient residual amounts of foaming agent or additional foaming agent may be added to the pre-expanded beads and the beads then further expanded by slowly heating the beads to soften and allow the foamed beads to further expand.</p> |
