Once this type of mold thermal fatigue crack ACD37 rod appears, you can not continue in service. Therefore, these service life of the mold, mainly determined by the thermal fatigue crack initiation time for ordinary die allows a certain size thermal fatigue cracks. Thus, the life of the mold ACD37, depending on thermal fatigue crack initiation and propagation speed at the time when the cold extrusion of metal black, thermal effects due to the severe deformation of the metal flow generated by the mold temperature, sometimes up to 150 ^ 4000C. Mold cyclical temperature changes may also cause thermal fatigue cracking and failure
