Forming tool

摘要

A forming tool, advantageously made from a metal with a forming contact surface (4, 5) and with one or several temperature regulation canals (T1) which are integrated in the tool (2, 2.1) and through which a fluid flows, characterized in that an electric conductor in the form of an inductor (9) is arranged at the internal wall of the temperature regulation canals (T1) and, if need be, with the insertion of a dielectric layer covering the temperature regulation canals (T1).

1. A forming tool, made from an electrically conductive metal with a forming contact surface comprising:
a first temperature regulation canal which is integrated in the tool at a closest distance from the contact surface and through which a fluid flows; a second temperature regulation canal through which a fluid flows and which is arranged at a longer distance from the contact surface opposite the first temperature regulation canal; andan internal wall of the first temperature regulation canal comprising a dielectric first layer deposited on a wall of the first temperature regulation canal, an electrically conductive second layer deposited on the dielectric layer and a third layer made of an electrically conductive material, the third layer being an inductor layer having a thickness of about 0.2 mm.
