Abstract
The work aims to increase the quality of the sheet metal embossing process used for car door caissons manufacturing.In order to obtain parts without defects, the cause of the defects, the moments in which they appear and the process conditions that favor their appearance are studied. For the processing of parts with complex and irregular shapes, optimal conditions for the flow of the material are necessary. If the degree of deformation is small, the stamping must be done by stretching the material and, therefore, retaining ribs must be provided. Thus, the edges of the semi-finished product are retained and the central part of the part will be subjected to a stretching process, thus avoiding the elastic return and ensuring the stability of the shape of the part
