Summary:To provide a novel and improved extrusion molding method capable of suppressing the push clogging of raw material.SOLUTION: An extrusion molding method has: a step of obtaining the proper ranges of the uniaxial decay stress and shear stress of raw material capable of normal extrusion molding in which the push clogging of the raw material is not generated; and a step of determining the raw material conditions of the raw material to be used so that the uniaxial decay stress and shear stress of the raw material to be used reach the proper ranges.SELECTED DRAWING: Figure 5 【課題】原料の押し詰まりを抑制することが可能な、新規かつ改良された押出成形方法を提供する。【解決手段】上記課題を解決するために、本発明のある観点によれば、原料の押し詰まりが発生していない正常な押出成形が可能な原料の単軸崩壊応力及び剪断応力の適正範囲を求める工程と、使用予定の原料の単軸崩壊応力及び剪断応力が適正範囲内になるように使用予定の原料の原料条件を決定する工程と、を含むことを特徴とする、押出成形方法が提供される。【選択図】図５
