In-line compounding machine (130), comprising: extruder (26) for producing, in use, homogenized melt, extruder (26) including feed throat (94) for receiving material to be compounded into melt, extruder (26) having barrel head; shooting pot assembly (24) having injection end; transfer channel (56) coupling extruder (26) to assembly (24); stationary platen (90) having: front wall (150); rear wall (152) having centrally located barrel opening (98); intermediate support structure (154) between walls (150, 152), intermediate support structure (154) defining hollow central cone region (102) accessible through centrally located barrel opening (98); wherein centrally located barrel opening (98) is configured to receive interconnected configuration of: barrel head of extruder (26), transfer channel (56), and injection end of assembly (24), interconnected configuration being retained in hollow central cone region (102) between and within walls (150, 152); and wherein extruder (26) and assembly (24) are acutely angled and laterally offset with respect to each other.

Dans une machine de moulage (130), présentée dans la FIG. 4, le décalage latéral et angulaire d~une extrudeuse à vis jumelles (26) par rapport à un ensemble de pot de tir (24) permet le raccourcissement d~un canal de transmission (56). Pour réduire de manière supplémentaire les effets de cisaillage résultant de la durée de résidence de la matière fondue, un adaptateur de bec (52), le canal de transmission (56) est situé à l~intérieur du cône cylindrique (102) d~une plaque d~appui (90), le cône cylindrique (102) typiquement formé par une structure de support intermédiaire en forme d~arche (154) couplant les parois avant (150) et arrière (152) de la plaque d~appui (90). Pour traiter le retrait de matière brute résultant de l~introduction d~une tête d~extrudeuse, du canal de transmission (56) et de l~extrémité de la tête de l~extrudeuse à l~intérieur du cône cylindrique (102), le renforcement d~une région supérieure de la paroi arrière (152) de la plaque d~appui (90) est accompli en utilisant un membre transversal (160, 164). Dans une application de composition en ligne, des longueurs diminuées pour le canal de transmission (56) et l~adaptateur de bec (52) réduisent les effets de cisaillage sur la matière fondue (en diminuant la durée de résidence de la matière fondue) et donc une longueur de fibre moyenne accrue dans une pièce moulée est obtenue.
