Hot Stamping - Process
� Blanks are heated to 950 º C in a furnace.� The heating time is important to achieve the
proper material structure.� The heated blank must be loaded into the
press a.s.a.p. to avoid cooling of the material.� The press has to close , draw the part and
keep it closed for several seconds.� During this time, the cooling circuits in the
upper and lower dies are cooling the part to200ºC (≈).

� Advantages of Hot Stamping:� High tensile strength.
� Reduction of the part weight.� Improvement of mechanical characteristics.
� High dimensional stability, no springback.� Reduction on the required press force (400
– 1.200 mT. for Hot Stamping instead of 2.500 mT. for Cold stamping).
