Abstract: A method for making objects (50) by forming a thermoformable sheet material (40), comprises forming said objects (50) by interaction of die means (2) and forming means (3), and comprises, before said forming, compressing and crushing a first portion (41) of said sheet material (40) by crushing punch means (5) and maintaining said first portion (41) crushed during said forming to reduce a thickness thereof and to orientate chains of molecules that compose a structure of said sheet material (40) at said first portion (41) so as to weaken said structure and make said first portion (41) weakened, in particular easily perforable, tearable and breakable.
