Abstract (en)

[origin: WO9928066A1] The invention provides an improved stopper rod which is made by a method in which a composition to form the body of the stopper rod is charged into a mould (10), a removable core (12) being positioned in the mould (10) to form a longitudinally-extending bore (31, 41) in the stopper rod body, an externally-threaded removable insert (16) being positioned in the mould in correspondence core (12) to form an internal thread (37, 43) on a portion of the bore and a plate (18) being positioned in the mould to define a flat upper end (35, 40A) of the stopper rod body, characterised in that a spacer (22) is positioned between the externally-threaded insert (16) and the plate (18) whereby the internal thread (37, 43) in the bore (31, 41) of the stopper rod body is formed spaced from the upper end (35, 40A) of the body when the composition is pressed in the mould. The invention also provides a mould in which to make the improved stopper rod.
