Abstract: A tool is disclosed for forming an article in a molding operation. The tool includes a first layer with a forming surface for forming the article. The first layer is formed from a first material having a hardness or corrosion resistance sufficient for the forming operation. The second layer is affixed to the first layer for collectively forming a tool body. The second layer is formed from a second material having different material properties than that of the first material, and the second material has sufficient structural integrity for withstanding stresses of the tool body during the forming operation. A tool is also disclosed having a series of laminate sheets collectively providing a portion of the tool body. Another sheet is affixed to the laminate sheets with a homogenous forming surface for forming the article in the molding operation.

Abstract: A tool is provided for forming an article in a molding operation with a body formed with a forming surface for forming the article. A heat transfer material is mounted to the tool body, spaced apart from the forming surface, and formed from a material having a coefficient of thermal conductivity that is greater than that of the tool body. The heat transfer material and/or the tool body collectively provide a duct for conveying a fluid for heat transfer with the forming surface. Another tool is disclosed for forming an article in a molding operation with a tool body formed from a plurality of laminate sheets of a first material. The tool body includes a forming surface and a cavity. A heat transfer material having a coefficient of thermal conductivity greater than that of the first material is disposed within the cavity for transferring heat from the forming surface.
