temperatures reached with good control over the cycle time when there is a highly deformed area localised in the centre of the part for example as for a drawing die the applicant was surprised to observe that the preheating area of the blank should be close to but not actually in the area to be formed to prevent failure during drawing added heat can only come from preheating of the blank and not from the tool since in this case contact between the tool and the blank is too fast to heat it sufficiently for example the blank could be preheated using a heating shim preferably located at a distance of more than 5 mm from the area of the blank corresponding to the highly locally deformed area of the part the blank is then transferred to the drawing tool and possible cooling of the blank between the exit from the furnace and the press has to be taken into account to obtain the desired temperature under the press so that the blank may be slightly heated above the tool temperature the preheated blank is then drawn one of the characteristics of the invention is that the drawing tool is also heated at least partially to a temperature between 150 and 350 u00b0 c this is obtained by incorporation of electrical resistances into the tool it is possible to heat only some areas of the tool preferably the die and the blank holder rather than the punch one particularly advantageous arrangement is to have a die in two heated parts separated by an air strip the result is thus a hot die edge under the cladding of the blank subjected to shrinkage and a colder die bottom to increase the mechanical strength of the blank at the radii of the.
