CONFORM EXTRUSION APPARATUS, CONFORM EXTRUSION METHOD, AND CONFORM EXTRUSION MATERIA

摘要

PROBLEM TO BE SOLVED: To provide a conform extrusion apparatus capable of manufacturing a conform extrusion material with less heterogeneous phase, a conform extrusion method, and a conform extrusion material.;SOLUTION: A conform extrusion apparatus, which continuously extrudes a conform extrusion material in a predetermined shape with a die by supplying, from a supply passage constituted of an annular groove continuous circumferentially in a rotatable wheel and a shoe that covers a part of the opening of the groove, via an abutment so arranged as to block the supply passage, an extrusion stock into a die chamber provided in the shoe, comprises a flow control part provided in a vicinity of the introduction port to force a partial region in the skin layer of the extrusion stock into pressure-welding, thereby making the flow rate into the die in the partial region of the skin layer relatively lower than that of another region of the extrusion stock.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
