Abstract

PURPOSE:To provide a high-density formed body usable as a substitute for wood by a method wherein scraps of formed plastic foam articles are pulverized into a desired grain size, added with reinforcing materials are required, and thermocompressed in a forming die. CONSTITUTION:Scraps of formed plastic foam articles are pulverized into particulates of a desired grain side, and added with reinforcing materials such as glass wool and waste fibers as required, to obtain a regeneration material 13. The regeneration material 13 is fed into a thermocompression steam chamber 14 of a forming device, and is compressed by a piston P while feeding steam from steam chambers 17 and 18 into the chamber 14 through many through-holes 15, 16. A plate-shaped formed body is obtained through the impact mating of a male die 1 and a female die 2.
