SQUARE PVC PIPE EXTRUSION FOR A MOLD

摘要

The present invention relates to a mold for extrusion molding a square PVC pipe. The present invention provides a seperable mold for extrusion molding a square PVC pipe between a vacuum cooling apparatus and an appratus for molding a compressed material for extrusion molding a circular PVC pipe so as to extrusion mold by converting the circular pipe extrusion molded with appropriate pressure in the appratus for molding a compressed material into a square, such that the present invention is economically excellent and working processe can be reduced compare with the existing method in which a squre PVC pipe is manufactured by hand, and thereby producing effects capable of mass production.
