Method for removing local plating of mobile phone shell

Abstract

The invention discloses a method for removing a local plating of a mobile phone shell. The method comprises the following steps: allowing a mobile phone shell product to pass through water, then placing the mobile phone shell product in chemical liquid and heating the chemical liquid; step 2, when a plating layer on a plastic part of the mobile phone shell product is completely removed, taking outthe mobile phone shell product and cleaning the chemical liquid on the surface layer of the mobile phone shell product; and step 3, storing and packaging the mobile phone shell product. Compared withthe prior art, the method provided by the invention has the following beneficial effects: the method can effectively remove the plating layer on the plastic part of the mobile phone shell product; the method has the advantages of short process flow, simple operation, low cost and capacity of effectively removing the plating layer on the plastic part of the mobile phone shell product without any damage to the mobile phone shell product compared with traditional removing means; and the method is suitable for extensive promotion.

Description

technical field [0001] The invention belongs to the technical field of mobile phone shell coating, and in particular relates to a method for partial deplating of a mobile phone shell. Background technique [0002] At present, some mobile phone cases are now injection-molded from aluminum and plastic (PBT, PE, PP, PVC, PS), etc. The surface of the aluminum substrate is an ionic crystal, which is not conductive in a non-melting state. Therefore, The plastic part will not be coated with a film layer, so there is no need for deplating. However, not all mobile phone cases are made of aluminum, a single metal and plastic, such as: there are other metal and plastic injection molding Yes, so the plastic part will still be coated with a film layer, so deplating is required. The traditional method of decoating is generally laser removal and overall deplating after applying masking oil. However, in the traditional method, the energy of the laser is relatively high and concentrated, s...

AI Technical Summary

Problems solved by technology

However, in the traditional method, the energy of the laser is relatively high and concentrated, so using the laser to remove the coating on the plastic part will not only make the surface of the plastic part rough, but also deform the plastic part due to high heat, and damage the metal substrate part. The film layer has some damage

However, after applying masking oil, the overall deplating process is cumbersome. Once the oil is not in place, the film layer of the metal part will be damaged during the deplating process.

In addition, sometimes, due to structural limitations, these two methods cannot effectively remove the film layer of the plastic part
