In addition, thermal shock the uneven plate billet heating temperature, die clearance and lower die fillet is too large, blank plan, severely bruised, BHF is too small or uneven can wrinkling and drum kits. After dough wrinkling, it is difficult through the shadow, the gap between the male mold, easily pulled off. Even overcast, the male mold, wrinkles can not be eliminated, will affect the quality of the head. High carbon steel and low carbon steel head ellipsoid can not afford to wrinkle conditions: Dp - Dm 20t prone to wrinkling and drum kits, so perfect mold, using
