<div>Forging is currently one of the most economical processes for the manufacture of parts for industry. Product quality and production costs are very significant factors for manufacturers today and determines their competitiveness. The design of preforms is an important aspect for improving the quality of forging parts and reducing the manufacture costs.This paper presents a new opportunity to design preforms for closed-die hot forging using a simple moving average smoothing technique. As examples, the preform design of axisymmetric forgings is performed. Computer simulations of the forging processes in the preform and final forging stages was carried out. The results are compared and analyzed.</div>
