Abstract

PURPOSE:To produce a multilayer resin molded body being free of combinations of component resins and avoiding thermal deterioration of the resins by a method wherein a plurality of resin materials are extruded in multiple layer as the temperatures corresponding to the melting points of respective resin materials are kept. CONSTITUTION:A mandrel 1 and the 1st-5th die head members 2-6 are fitted from inside to outside and the 1st-3rd molten resin passages 7, 9, 10 are formed through which fluids are joined one after another, reach an extruding hole 8. A resin multilayer extruding die is formed by arranging the 1st-3rd heating means 15, 16, 17 and cooling means 19, 20, 21 which correspond to each passage. When resin materials flowing in the 2nd passage 9, 3rd passage 10 are laminated around the resin material flowing in the 1st passage 7 one after another using said die to form a parison member of the three layers, each resin material flowing in the passages 7, 9, 10 is extrusion-molded by said heating, cooling means at suitable temperatures corresponding to respective melting points to obtain an excellent multilayer laminated body.
