<p>This disclosure relates generally to molded cellular foam parts and, more specifically, to methods of manufacturing cellular polyurethane foam parts. In an embodiment, a polymer production system includes an energy source (21) configured to provide activation energy (19) to a foam formulation (28) to produce a foam part (12). The system further includes a polymeric mold (14) configured to contain the foam formulation within a mold cavity during the manufacture of the foam part. Furthermore, the mold is configured to not substantially interact with the activation energy that traverses the mold during the manufacture of the foam part. The system also includes a semi- permanent surface coating (52) disposed on a surface of the mold cavity that is configured to facilitate release of the foam part from the mold cavity.</p> |
