Abstract
PURPOSE: To accurately produce a molded article having protuberances and recessed by a method wherein a particulate plastic material having a specified particle size is placed in a closed mold and is molded by heating while rotating the mold.
CONSTITUTION: A particulate plastic material having a particle size (diameter in the case of spherically shaped particles; length of one side in the case of cubic particles) of 0.2W3mm, preferably 0.6W2mm and colored in two or more colors is placed in the closed mold and is heated (preferably, by oil heating) at a temperature of, preferably, 200W250°C while rotating the mold to obtain a molded article.
EFFECT: The resultant article has individually colored parts and mixedly colored parts dispersed at random, instead of being uniformly colored in a mixed color, and is beautiful in appearance.
USE: Toy bricks for children and the like.
