This invention discloses a method for manufacturing a protective shell. A masking element is first injection molded onto the surface of the bonding area or areas that do not require painting. During subsequent painting operations, the masking element is used for painting. The masking element effectively protects the bonding area and areas that do not require painting, preventing paint from adhering to their surfaces. After painting is complete, the masking element is peeled off using physical or chemical methods to expose the bonding area and areas that do not require painting. Because these areas are free of paint, the bonding area can bond normally with other parts without the need for CNC machining, polishing, or grinding. By injection molding the masking element, the bond between the masking element and the bonding area is tight. During painting operations, paint will not seep into the surface of the bonding area. This solves the material waste caused by CNC machining of the bonding area with paint adhering to it, and also ensures that the surface of the bonding area is not contaminated by paint.
