MANUFACTURE OF THERMOPLASTIC SUBSTANCE CHARGED, CHANGED AND REINFORCED WITH FIBER AND TWIN-SCREW TYPE EXTRUSION MOLDING MACHINE FOR EXECUTION THEREOF

摘要

PROBLEM TO BE SOLVED: To give a high mechanical stability, a high impact resistance, crush- proofness at breakage and the dimensional stability at an injection molding to a produced thermoplastic substance. SOLUTION: Only in a manufacturing process, a polymer as a matrix is supplied together with a blending polymer to a twin screw type extrusion molding machine 2. After the melting of the matrix, a filler is fed through a feeding device 8. Next, fiber rovings 12 are fed under the state being cut into long fiber chops to the matrix.
