Abstract (en)
[origin: EP2684627A1] A method to manufacture a forming tool, which method can be used in material shaping processes involving heat transference from the shaped part into the forming tool and from the latter to a cooling medium, through the provision of a permanent or semi-permanent isolating and/or releasing layer over the in-cavity surface of the die in combination with the use of high thermal conductivity materials for the die. This method allows to severely reduce the manufacturing cost of the produced part through productivity/durability optimization and continuous monitoring of the process. The system is applicable for all material forming processes involving the heat transfer from the formed part to the forming tool and cooling down of this later during the consecutive forming cycles, in particular for High pressure die casting, semi-solid die casting, squeeze casting, hot forging, hot glass forming and tube manufacturing amongst others.
