What are the requirements for protective film in the manufacturing process of 5G phone back covers?

With the continuous development of 5G technology, 5G mobile phones have become one of the hottest products in the market. However, in the production process, the back cover process of 5G mobile phones needs to use a protective film to protect its surface to ensure the quality and performance of the product. This article will discuss the requirements for the protective film in the back cover manufacturing process of 5G mobile phones.

1. Surface protection of wire drawing stamping parts: Wire drawing stamping parts are one of the main processes for manufacturing mobile phone casings. During the production process, the surface of wire drawing stamping parts is easily scratched or worn, which affects the aesthetics and service life of the product. Therefore, the protective film must be able to effectively protect the surface of the drawing stamping parts and prevent scratches and wear.

2. High-temperature molding surface protection: High-temperature molding is another important process for manufacturing mobile phone casings. During the high-temperature molding process, the mobile phone case is susceptible to oxidation and corrosion, resulting in a decrease in the gloss and color of the surface. Therefore, the protective film must be able to withstand the high temperature and corrosion during the high-temperature molding process to ensure the quality and aesthetics of the mobile phone case.

3. PC board surface protection: PC board is one of the common materials for manufacturing mobile phone casings. When CNC cuts PC boards, not only the surface is easily scratched or worn, which affects the quality and appearance of the product. Therefore, the protective film must not only be able to effectively protect the quality and appearance of the surface of the PC board, but also need the protective film to be lint-free and non-foaming when cut by CNC.

4. Surface protection of prism sheet: Prism sheet is one of the key components of mobile phone camera. During the production process, the prism sheet is easily affected by collision or abrasion, causing cracks or scratches on its surface, which affects the quality and performance of the product. Therefore, the protective film must be able to effectively protect the quality and performance of the surface of the prism sheet.

5. PET coating surface protection: PET coating is a common material for making mobile phone screens. The surface of the PET coating is easily scratched or worn, which affects the quality and appearance of the product. Therefore, the protective film must be able to effectively protect the quality and appearance of the PET coating surface.

To sum up, the 5G mobile phone back cover process has many requirements for the protective film. These requirements include: protecting the surface of brushed stamping parts from scratches and abrasions; protecting mobile phone casings during high-temperature molding processes from oxidation and corrosion; protecting PC board surfaces from scratches and abrasions; protecting prism sheets Protects surfaces from impacts and abrasions; protects PET coated surfaces from scratches and abrasions. Only a protective film that can meet these requirements can effectively protect the surface of the 5G mobile phone back cover and ensure product quality and performance.
