In order to meet the increasing requirements introduced by European Union directives and guidelines for the automotive industry, in the area of increasing safety while constantly reducing carbon dioxide emission limits, companies in the automotive industry implement new materials and new technologies for production. Currently, two trends are propagated in the way of manufacturing car body elements: the cold forming process of steel with a tensile strength Rm up to 1600 MPa and the hot forming process of steel with a strength Rm of up to 1800÷2000 MPa. The largest European manufacturers of car parts must meet the design and manufacture of hot forming tools. It is one of the most modern pressing technologies implemented for several years in innovative plants located both in Europe and the USA. Designing and testing of this type of tools are carried out by companies with advanced technological production capabilities. The use of this type of technology increases the level of product innovation, due to the know-how of companies for such complex tools, despite the fact that the costs of tools significantly exceed the costs of standard dies. The competition on the European market in the production of parts in hot forming process is not so large at the moment. |
