This paper shows example results of computer simulations supporting the production process of sink. Design and verification of deep drawing process and tools design were carried out using finite element models implemented in Inventium Suite. Wrinkling and fracture of the material were the main phenomena subjected to the investigation using numerical analysis. A number of computer simulations were carried out in order to eliminate defects and analyze the shape of the final product.
