Document Type and Number:
Japanese Patent JPH11129230
Kind Code:
A
Abstract:

To eliminate the influence due to the springbcak of organic foamed particles and give a sharp relief pattern with favorable reproducibility to the surface with relief pattern in the extrusion molding of a product, in which the organic foamed particles are added for lightening the product.

The manufacturing method consists of processes, in which inorganic kneading material added with organic foamed particles is extrusion- molded in a continuous formed body having a predetermined sectional shape and then, onto the surface of a shaped body just after being extrusion-molded, an inorganic compounded stock made of the same quality as that of the inorganic kneading material including no organic foamed particle is laminated by the resultant layer thikness of 1/4-1/1 of the height of the raised part of a resultant relief pattern by pressing a relief pattern from above the resultant front layer and finally the resultant shaped body is cured and hardened by conventional procedure.
