Abstract
A heat insulating panel (20) for a mold tool (14) includes a surface for being mounted onto a section of the mold tool. The panel has an exposed upper surface (29) and a thickness great enough to provide heat insulation sufficient to maintain the temperature at its exposed upper surface lower than the melting temperature of a powder plastic resin (13) that is melted and cured onto the mold tool. Any powder plastic resin on the upper surface remains in powder form during molding such that the powder may be returned to a powder box (12) and be reused. The heat insulating panel (20) has a periphery (21) that covers the entire periphery of the mold tool.
