METHOD AND DEVICE FOR EXTRUSION MOLDING OF CONTINUOUS COMPONENT

摘要

PROBLEM TO BE SOLVED: To extrusion mold efficiently the whole length continuously while increasing the molding freedom of the chanel shape and the whole shape. SOLUTION: The extrusion molding is so carried out as to change the sectional shape of a channel molding site and form a swelling section 21a, and the whole length is continuously extrusion molded in a series integrally while forming a channel 28 of sufficient size on the swelling section 21a formed by the variation of the sectional faces to make the selection of the shape of the swelling section 21a and the shape of the channel 28 selected comparatively and optionally, and make the length of a continuous component extrusion moldable efficiently.
