The UV transfer process, also known as the UV infusion process or the UV coating process, utilizes the characteristics of UV transfer glue and metal non-stick, and transfers the ultra-thin button effects of various mobile phones to PET or PC sheets through the UV transfer process. Thus, including ultra-thin buttons such as CD pattern, hard wire drawing, matte surface, bright surface texture and key type, such as digital keys, red and green phones, blind spots, etc., ultra-thin buttons, lenses, navigation keys and product signs .

At the same time, this process is widely used in PET and PC sheets, and the effects of the whole surface of the brushed wire are made, thereby fundamentally replacing the ultra-thin button process of injection molding.
