METHOD FOR SEPARATING FLAT IRREGULARLY-SHAPED CROSS SECTION PIPE MADE OF ALUMINUM OR ALUMINUM ALLOY FROM WAX-COATED THIN WALL FLAT IRREGULAR-SHAPED CROSS SECTION TUBE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a flat irregularly-shaped cross section pipe having a decent burrless separation/cut part without significantly changing the manufacturing cycle.;SOLUTION: In this method for separating the flat irregularly-shaped cross section pipe from a thin wall flat irregularly-shaped cross section pipe strand coated with wax, for example, an extrusion-molded flat irregularly-shaped cross section pipe strand, especially a thin wall multilocular irregularly-shaped cross section pipe strand coated with wax used for a heat exchanger, the wax coating on the flat irregularly-shaped cross section pipe strand is mechanically removed before separating and cutting the intended place to be cut.;COPYRIGHT: (C)2004,JPO
