Abstract
In this study, the selection of thermal insulation materials and the design of a mechanical insulation curtain for rubber injection molds were discussed. First, experimental tests were performed on a rubber mold to determine the most suitable insulation materials, which were mica plate, resin bonded glass fiber plate and ceramic fiber paper. Cost and thermal performances were also analyzed for these materials. According to experimental observations ceramic paper is considered the most suitable product for curtain material. Furthermore, a new design is proposed which has a radiation curtain mechanism. It was developed for rubber presses without requiring special materials for each mold. This mechanism presents an innovative design for preventing heat transfer in this type of manufacturing process.
