EXTRUDER FOR THERMOPLASTIC MATERIAL

摘要

PURPOSE: To prevent the generation of an M-shape or a W-shape by minimizing differential cam sharing. CONSTITUTION: An extrusion molding apparatus 50 for the extrusion molding of a thermoplastic material has first and second die main body parts 52, 54 prescribing a manifold 60 having a back line 71 and the manifold 60 is fluidally connected to an outlet 64 for extruding a thermoplastic resin and the back line 71 is substantially parallel to the outlet 64. First and second main body bolts 70 are arranged at first and second equal distances from the back line 71 and arranged at third and fourth unequal distances from a center line 94 on both mutually opposed sides of the center line 94 and the first and second main body bolts 70 are arranged at a substantially equal distance from the outlet 64.
