Methods for their preparation as well as aluminum and plastic injection molded products together using the same shape and aluminum body of aluminum and plastic injection molded products integrated manufacturing

摘要

Aluminum can be effectively prevented and the generation of dust from the surface of the aluminum-shaped body, the reduction of air tightness and adhesion strength of the resin near the gate in the resin bonding surface between the resin molding and the aluminum-shaped body, aluminum and resin injection integrally molded products aluminum body shape of resin injection integrally molded product manufacturing, and using the same, and I will provide a method for producing them. An aluminum-shaped body having a projecting portion projecting cornice shape from the concave portion due to the concavo-convex portion formed on the surface, in the direction cross the thickness, the thickness toward the uneven portion of the aluminum shaped body from the space side when it is drawn at intervals of 0.1μm each other observations a number of lines which extend in the direction, the space on the basis of the protruding portion - Aluminum - viewing line passing through the space, more than 150 800 (100μm wide) per observed section Aluminum-shaped body is the less, aluminum resin injection molded article together and using the same, as well as processes for their preparation.
