    Abstract: The present invention relates to a method for manufacturing a screw cap(12), wherein the screw cap having a blind hole with inner threads. The method comprising the steps of placing a piece pre-preg MFC (11), of a suitable size for forming the screw cap, between a first tool (1) comprising a protruded part (2) with outer threads (4) for forming the inner threads (17) of the blind hole (14),and a second tool comprising a section (22) with an inner lateral surface (25) for forming an outer lateral surface(18) of the screw cap, moving the protruded part of the first tool into the section of the second tool, such that,the first and the second tool forms the screw cap,drying the piece of pre-preg MFC, such that it is shrinks onto the first tool and thereby forms the screw cap, and unscrewing the formed screw cap from the threads of the protruded part of the first tool.
