Problem projekta je bil pojav mikropor in lomljenje kavitete. Reševali smo ga s pomočjo izkustvene in eksperimentalne metode. Izkustvena metoda se je izkazala zelo dobro, saj imamo v podjetju veliko izkušenj na podlagi oblikovanja orodij za globoki vlek ALU-PVCD folije. Naredili smo štiri različne oblike pestičev. Eksperimentalni rezultati oblik A, B in D so bili slabi, kajti še vedno je bil prisoten pojav mikropor in lomljenje kavitete. Oblika C je pa zagotovila vse zahteve in se izkazala za najboljšo.The problem of the project was the appearance of micropores and the breaking of the cavity. We solved it using an experiential and experimental method. The experiential method proved to be very good, as we have a lot of experience in the company based on the design of tools for deep drawing of ALU-PVCD foil. We made four different shapes of fists. The experimental results of forms A, B, and D were poor, as the appearance of micropores and cavity fracture was still present. Form C, however, met all the requirements and proved to be the best
