RESIN MOLDING CUTTING METHOD AND RESIN MOLDING CUTTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a resin molding cutting method and device capable of thermally cutting a resin molding with high accuracy and contiunuously at high speed. SOLUTION: A heating line 8 is composed of a heating element extending in band shape with its cross section S shaped to be larger in width than the thickness. The heating line 8 is formed in thin plate shape so that the ratio (H/W) of the width H to the thickness W of the cross section S is 1.5-100, preferably 2.5-25. A molded sheet is thermally cut with the heating line 8 by being moved to cross the heating line 8 from one end side to the other end side in the width direction of the heating line 8 of such a shape.
