Cold extrusion is an economic production process for the production of elements of complex forms and accurate dimensions. The first part of the article explains the impact that a mechanical press has on the accuracy of products. It describes the mechanical press main characteristics and in addition, based on individual examples the impact of these characteristics on the accuracy of products is shown. Further on, the impact of rigidity to thickness of starter clutch barrel bottom, for rigid and softer press, is described. The second part presents analysis of the impact that scatter of the blank mass has at different press rigidities. In addition, an example of measuring dynamic rigidity of 1000-ton mechanical press during the process of starter barrel cold extrusion is given.
