  • Patent number: 10807287
    Abstract: A method for manufacturing an elongated element (200) is provided. The method comprises arranging a molding cavity (101), defined by a mold (103) and a mold insert (104), said mold insert (104) comprising a mold core (105) and a displaceable mold cavity wall (106), said displaceable mold cavity wall (106) being arranged between the mold (103) and the mold core (105), such that the molding cavity has a start volume in a start position of the displaceable mold cavity wall (106). Then a liquid material is injected into a proximal end (102) of the molding cavity (101), where after the displaceable mold cavity wall (106) is displaced in relation to and along with the mold (103) and the mold core (105), distally during said injection, to increase the molding cavity volume from the start volume into an end volume at an end position of the displaceable mold cavity wall (106), wherein the molding cavity (101) in said end position of the displaceable mold cavity wall (106) corresponds to the elongated element (200).

  • Publication number: 20150025508
    Abstract: A method for manufacturing an elongated element (200) is disclosed. The method comprises arranging a molding cavity (101), defined by a mold (103) and a mold insert (104), said mold insert (104) comprising a mold core (105). A liquid material is then injected into a proximal end (102) of the molding cavity (101), and the material is solidified, such that the elongated element (200) is formed. The elongated element (200) and mold insert (104) are removed from said mold (103), and the elongated element (200) is removed from said mold insert (104), wherein said removal of said elongated element (200) from said mold insert (104) comprises injecting a fluid in the interface between the elongated element (200) and the mold core (105). A mold assembly for the manufacture thereof is also provided.
