This paper discusses the use of conventional forging equipment for the manufacture of precise forging without flash. An analysis is presented of the factors influencing the forging process and the conditions for establishing this technique in a forge based on practical experience at the SKODA Auto forge. The main problem is usually the excess volume of billet material. Three basic forms of die design for overload protection are illustrated and discussed.
