Abstract
A method for producing a ceramic molded body, the method including: a molding step of subjecting a ceramic molding material to extrusion molding using an extrusion molding machine equipped with a temperature control portion to provide a ceramic molded body; a cutting step of cutting the ceramic molded body to have a predetermined length; and a dimension measuring step of measure a dimension of the cut ceramic molded body. A relationship between a temperature of the temperature control portion and the dimension of the cut ceramic molded body is previously obtained, and based on the relationship, an appropriate temperature of the temperature control portion is calculated from the dimension of the ceramic molded body measured in the dimension measuring step, and the temperature control portion is controlled to the appropriate temperature in the molding step.
