Abstract: The present disclosure provides a metal-resin composite and a method of preparing the same. The metal includes titanium or titanium alloy, the composite includes a metal substrate and a resin layer coated on at least a part of a surface of the metal substrate, recesses are distributed on the part of the surface of the metal substrate coated with the resin layer, a part of resin of the resin layer extends to fill in the recesses, and a concentration of an oxygen element on the surface of the metal substrate is greater than 1 wt %. The method includes dipping a metal substrate in an etching solution containing at least one alkali metal hydroxide so as to form recesses on the surface of the metal substrate, and injecting a resin onto the surface of the after-surface-treatment metal substrate to form a resin layer. The metal-resin composite of the present disclosure is suitable for a shell of an electronic product.

Abstract: The present disclosure provides an electronic product metal shell with an antenna groove and a method of manufacturing the same. The electronic product metal shell includes a metal layer, a hard anodic oxidation layer, a step recess, an antenna groove and a non-conductive material filled in the antenna groove. The metal layer may have a first surface and a second surface. The hard anodic oxidation layer may be coated on the first surface and the second surface of the metal layer. The step recess may be formed through the hard anodic oxidation layer on the first surface of the metal layer and partially into the metal layer. The antenna groove may be formed within the step recess extending through the metal layer to expose an inner side of the hard anodic oxidation layer on the second surface of the metal layer.
