A Study on Surface Topography Assessment and Aesthetic Quality of Injection Molded Plastic Surfaces

摘要

Most plastic surfaces are textured to suppress specular reflection and to enhance their aesthetic quality. Those surface textures are generated in the injection molding process. First of all in this paper, some significant 3-D geo-statistical parameters for assessing the textured surfaces were selected and their measuring conditions were introduced. Geometrical transfer from the mold to the plastic surfaces could be evaluated by the parameter values.
