Abstract
In one embodiment, a tool for forming an article in a molding operation has a tool body formed from a non-particulate material, with a particulate material bonded to the body. The body provides a forming surface for forming the article. The particulate material, or the particulate material and the tool body collectively provide a duct for conveying a fluid for transfer of heat with the forming surface. In another embodiment, the tool has a tool body formed from a non-particulate material with a cavity and the particulate material is disposed within the cavity. A heat transfer material is disposed in the cavity bonding the particulate material to the tool body. Methods for manufacturing such tools are also disclosed.
