Embodiment Construction
[0028] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.
[0029] Examples, see attached Figure 1~Figure 2 , a 3D gradient mobile phone back cover molding process, which comprises the following steps:
[0030] 1. Cutting: use a glass cutting machine to cut the glass, and cut out a glass piece that matches the size of the back cover of the mobile phone when it is spread out. The thickness of the glass is 0.5-1.0mm;
[0031] 2. Hot bending forming: Use a glass hot bending machine to hot bend the glass sheet in step 1. When hot bending, put the glass sheet in step 1 at 80°C, 100°C, 200°C, 300°C, 400°C in sequence Heating and softening at lower temperature, followed by multiple downward hot pressing at 500°C for micro-deformation, and finally multiple downward hot pressing at 680°C to form a semi-finished glass back cover 1 whose shape matches the shape of the back cover o...
