摘要： The invention relates to a heatable tool for a device, which processes a plastic melt or a metal melt, comprising a surface that comes into contact with a melt. An electrically conductive ceramic (16, 54, 116, 154, 216, 254) for heating, at least in the area of the surface, is provided in therein or is integrated therewith. In order to improve the design of the heatable tool, the invention provides that cooling channels (220) for conducting a cooling medium are made in the electrically conductive ceramic (216). The invention also provides that the electrically conductive ceramic (16, 54, 116, 154, 216, 254) is designed as an insert for inserting into a tool base structure, whereby the insert, particularly by oxidation, has, at least in part, an electric insulation. Lastly, the invention provides that a nanostructure is applied to the electrically conductive ceramic or, alternatively, a ceramic structure system consisting of an electrically conductive ceramic and of an electrically non-conductive ceramic is created.

摘要： The tool incorporates an electrically conductive ceramic part (16) which heats a tool member at least in the area of a surface (18) which contacts the molten material. The ceramic part is integrated in or with the tool member (12,14). The tool incorporates an electrically conductive ceramic part (16) which heats a tool member at least in the area of a surface (18) which contacts the molten material. The ceramic part is integrated in or with the tool member (12,14). A controlled low voltage with high current is passed through the ceramic part (16) to achieve a high heat output in the latter. The ceramic may be sandwiched in the tool member (12,14) so that it lies close to or immediately below a melt contacting surface (18). Connection between the ceramic part and another part of the tool, e.g. a housing part or supporting part, is preferably by diffusion welding. The ceramic part may alternatively have a surface which contacts the melt and forms a cavity surface or a hot runner channel. For the latter a ceramic with high abrasion resistance is employed. The ceramic surface may be shaped to match the forming cavity profile. When cooling channels are required in the ceramic they are produced by erosion. The ceramic part may be mounted on a tool steel member (14) which acts as a carrier. Specific areas of the ceramic part surface may be electrically isolated. Current may be supplied by mounting the ceramic part on an electrically conducting surface.
