diameter of a stamp 12. The stamp is hollow and has bores 23 and 24 to intake and outtake the coolant (50%

ethylene glycol solution) and has a tight cap 13 made of material having heat conductivity greater than that

of stamp material 12. The stamp cavity 12 is filled with coolant (50% ethylene glycol solution), connected by

the heatisolated pipe lines via the three-running cock 25, a cooler 26, the cock 27 to coolant reservoir 28.
