EXTRUSION MOLDING MACHINE FOR CERAMIC MOLDING

摘要

PROBLEM TO BE SOLVED: To provide an extrusion molding machine for a ceramic molding capable of enhancing rigidity of a screw shaft, increasing in its length and sufficiently enhancing an extrusion pressure. SOLUTION: In the extrusion molding machine 1 comprising a screw extruder 12 having a screw shaft 2 including a shaft 20 and a screw piece 22 spirally wound on a periphery of the shaft 20 and rotatably contained in a material channel 30 of a housing 3, and a mold 11 provided at an end of the extruder 12 to extrusion mold a ceramic molding 8 of a desired shape; the extruder 12 has an intermediate bearing 4 for supporting the shaft 2 on the way of the channel 30 of the housing 3.
