technical field

The invention belongs to the technical field of camera decorative rings, and in particular relates to an electroformed mold camera decorative ring, a manufacturing method of the decorative ring, and a mobile terminal.

Background technique

At present, many mobile phones on the market use a hardware camera decorative ring, and this camera decorative ring is basically processed by a stainless steel CNC milling machine. The production process is complicated and the processing cost is very high.

Electroforming refers to the process of electrodepositing on a mandrel and then separating it to make (or replicate) a metal product. Its basic principle is the same as electroplating. However, in electroplating, a metal coating that is firmly bonded to the substrate is required to achieve the purpose of protection and decoration, and the electroforming layer must be separated from the core mold, and its thickness is much larger than that of the electroplating layer.

Electroforming can transform the inner surface of the parts that are difficult to machine into the outer surface of the core mold, and can convert the difficult-to-form metal into the easy-to-form core mold material, so it can produce special shapes that cannot (or are difficult) to manufacture by other methods. parts. Due to the above characteristics, electroforming is used to manufacture hollow parts with complex shapes and high precision (such as waveguides, etc.), molds for injection molding, thin-walled parts (sometimes only tens of microns thick), and to replicate fine surface profiles ( Such as record molds, artworks), etc., will become one of the widely used crafts.
