Cell phone frame and method for manufacturing the same

Abstract

A cell phone frame includes a composite plate, the composite plate encloses a accommodation space for accommodating the cell phone, the composite plate includes a first plate and a second plate, a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations. The first side surface of the first plate is roughened to form striations, which increases the area of the first plate and the second plate subjected to rolling, so that a composite plate produced by combining the first plate and the second plate has a higher bonding strength, thereby ensuring that the cell phone frame is firmer.
