METHOD FOR DECORATING AND EXTRUSION MOLDING EXTRUSION- MOLDED PIECE

摘要

PROBLEM TO BE SOLVED: To provide an extrusion-molded piece having the surface decorated with a ceramic touch at a low cost. SOLUTION: Moisture-adhering resin pellets are loaded into a hopper 21 of an extrusion molding machine 15 and a molten resin containing moisture obtained by melting the pellets inside the machine 15, is sent under pressure by a screw 24. Next, the molten resin containing the moisture is extruded from a die 25 and consequently, a decorative surface is formed by spew holes generated when the contained moisture is vaporized from the resin.
