The topic of this paper are the types of engravings in the forging die, the process of their production, and durability of the engravings inside the forging die. Serial and mass production of forgings is carried out by forging in a forging die. The forging die consists of an upper and a lower forging die, and it usually contains several cavities in which the forged material achieves desired shape. The forging process requires a gradual change of shape, which is carried out in several stages. Forging cavities can be final, preparatory and for material cutting. The forging die is produced from a single piece of material, mostly tool steel for hot work. The forging die material must be resistant to tempering and wear due to working at high temperatures. The form of engraving in forging die is achieved by machining. The quality of the surface of the forging engraving directly affects the surface quality of the produced forgings. After processing by machining, the forgings are heat-chemically treated, in order to extend the durability of the forging die cavities, and the working life of the forging die. The forging die cavity is highly stressed when the upper forging die strucks lower one. The form of the engraving then wears out, thus the durability of the forging die is limited and depends on numerous factors. The greatest wear of the engraving appears in the places where the forging and the engraving are in longest contact. The durability of the engraving mostly depends on the complexity of the engraving form and the forging method.
