Abstract
Three-dimensional multi-colored plastic parts and a method for manufacturing such parts for automobile interior trim door panels, consoles and instrument panels and the like includes dry cast thermoplastic powder sized in the range of 60-400 microns and with two or more colors of particles mixed for distribution onto a heated mold section with the mixed powder particles being heated to randomly flow at particle margins to form two or more shade tones in a resultant three-dimensional multi-colored textured part of fuzed material.
