INTERNAL STATE DETECTION METHOD AND MANUFACTURING METHOD OF EXTRUSION MOLDED BODY, AND EXTRUSION MOLDING APPARATUS, AND EXTRUSION MOLDED BODY

Japanese Patent JP2016210170

A

PROBLEM TO BE SOLVED: To provide an internal state detection method by which an internal state of an extrusion molded body including a core layer and a skin layer covering the core layer can be easily detected, and an extrusion molded body, and a manufacturing method by which an extrusion molded body having an appropriate internal state can be easily manufactured, and an extrusion molding apparatus.SOLUTION: There is provided an internal state detection method of an extrusion molded body 1 that is molded by extruding a core molding material 15 and a skin molding material 16 for molding a skin layer 11 that coats a core layer 10 which is formed of the core molding material 15. An inspection wave consisting of an electromagnetic wave is emitted from emission means 50 toward the extrusion molded body 1. The inspection wave having transmitted through the extrusion molded body 1 is detected by detection means 51. Internal information of the extrusion molded body 1 acquired on the basis of a detection result is output.SELECTED DRAWING: Figure 1
