Marble-color molded product and marble color effect evaluation system

A system for evaluating a marble color effect of a marbled molded product which is an injection-molded product of a mixture, the mixture comprising:

• a thermoplastic resin comprising one selected from the group consisting of polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof;
• and
• fine pigment particles,
• wherein the system comprises:
• a light source unit that emits light onto a surface of the injection-molded product while forming an angle with the surface of the injection-molded product;
• an image-capturing unit that captures an image of light scattered from the surface of the injection-molded product;
• an image processing unit that processes the image captured by the image-capturing unit in order to determine boundaries of regions in which the marble color effect is created on the surface of the injection-molded product;
• and
• an evaluation factor determination unit that determines a marble color effect evaluation factor from the image processed by the image processing unit, and
• wherein the marble color effect evaluation factor is at least one of:
• the number of the regions in which the marble color effect is created;
• the average size of the regions in which the marble color effect is created;
• and a difference in average color brightness between the regions in which the marble color effect is created and a region in which the marble color effect is not created.
