Abstract
This paper describes the possibilities and conditions of the closed-die flashless forging process using conventional mechanical presses and equipment. The technique of driven gear forging with an internal flash or with special die design has been developed. The quality of forgings is comparable to that achievable on Hatebur presses. Furthermore the problem of how to increase shift production under the same conditions so that the same quality and accuracy are achieved will be discussed. The material flow in the die cavity is affected by die design. Numerical simulation was used to optimise this process.
