ABSTRACT:
A method for manufacturing shaped articles of organic substance is disclosed, which comprises mixing an organic substance as raw material with a binder, filling a die with the resultant binder-containing mixture, compressing the mixture in a prescribed shape in the die, and forcing a gaseous curing agent through the compressed mixture thereby curing the binder in the mixture and consequently solidifying the compressed mass. This method enables shaped articles such as noise absorbers, heat insulation panels, and plate materials to be produced efficiently and inexpensively at low energy consumption by the use of an inexpensive die.
