COMMUNICATION DEVICE METAL HOUSING

摘要

Disclosed is a communication device metal housing, the communication device metal housing comprising: a metal substrate (100); a slit (200) passing through an inner surface and an outer surface of the metal substrate (100); a plastic supporting layer (300) formed on the inner surface of the metal substrate (100); and a decorative layer (400) formed on the outer surface of the metal substrate (100); the slit (200) has a width of 15-500 μm on the outer surface of the metal substrate (100), and the slit (200) has a width of 20-600 μm on the inner surface of the metal substrate (100); regarding the slit (200), a ratio of the width on the inner surface of the metal substrate (100) to the width on the outer surface of the metal substrate (100) is (1.05-1.5):1.
