Abstract
Un injecteur dun appareil à moulage par injection comprend un corps dinjecteur doté dun premier segment, dun deuxième segment et dun troisième segment. Le deuxième segment est raccordé de façon amovible à au moins lun ou lautre du premier et du troisième segment. Le premier segment et le troisième segment sont chauffés soit par le premier ou le deuxième élément chauffant dinjecteur, respectivement, soit par un manchon délément chauffant doté dune entaille le long du deuxième segment. Le deuxième segment est essentiellement dépourvu délément chauffant dinjecteur de sorte que le deuxième segment est chauffé passivement par le contact avec le premier segment et le troisième segment.
