Title: METHOD FOR MANUFACTURING EXTRUSION MOLDING
Abstract:
Provided is a method for manufacturing an extrusion molding, the method being capable of manufacturing an extrusion molding with minimal unevenness of quality using simple maneuvers. This method for manufacturing extrusion moldings comprises: (1) a step for manufacturing a kneaded product by kneading a starting material powder, a liquid and a binder; (2) a step for manufacturing a crushed product by crushing the kneaded product; and (3) a step for molding the crushed product using an extruder. The crushed product in step (2) is crushed to a particle size such that 80 mass% or more passes through a sieve of nominal dimension (D/2) mm when the internal cylinder diameter of the extruder in step (3) is D mm or is crushed using a crusher in step (2).
