Cold extrusion is an economic production process for the production of elements of complex forms and accurate dimensions. The first part of the article is about the impact that mechanical press has on the accuracy of products and reliability of tools. There is a description of the mechanical press main characteristics and in addition, individual examples show the impact of these chracteristics on the accuracy of products. Further on, the impact of rigidity to the thickness of starter clutch barrel bottom, for rigid and softer press, is shown. The second part presents the tools and entire system the formed part, tools, press rigidity. There is also an analysis of the impact that scatter of the blank mass has at different press rigidities. An example of measuring dymanic rigidity of 1000-ton mechanical press during the process of starter barrel cold extrusion is shown.
