Abstract
PURPOSE: To prevent the generation of a press force locally exerted on a spot being to form a hole part and to prevent the occurrence of local rupture by a method wherein hollow holes are formed, protrusion parts are formed on the surface and the back, and by cutting the protrusion parts, perforations are formed, in a base material. CONSTITUTION: A base material 1 of a decoration perforation board is manufactured through an extrusion molding method and has hollow holes 4 and an uneven surface is formed on the surface and the back of the base material. By cutting a part of protrusion parts 2 and 3 formed on the surface and the back of the base material, perforations 10 and 12 are formed. As noted above, to form holes in the base material, a press force in a vertical force is not exerted on the base material for processing but by exerting a cutting force, processing is executed, whereby no force is locally exerted on a spot being to form a hole part and local rupture is prevented from occurring at the periphery of a hole.
