Abstract

PURPOSE: To manufacture a forming material having high apparent density, smooth surface, and a small amount of fine particles, by pressing, kneading and granulating raw material for thermosetting forming material containing evenly mixed fibrous raw material, and by refining the surface of the granulated surface.
CONSTITUTION: Raw material for thermosetting forming material containing fibrous raw material is well-mixed. To this is added 5W7wt% of thermoplastic material. The resultant substance is kneaded under pressure of 0.3W0.8kg/cm2, at 50W90°C for 3W6min/10kg. After this, the substance is extruded into noodles, 1W4mm in diameter; then, this noodle-shaped substance is crushed into grains, 2W10mm in length. Fine grains produced by the crushing are removed. After this, by using a rotary mixer, rough grain surfaces are ground by using water and methanol.
