In step 101, transparent plastic is injected into a preset injection mold to obtain a transparent plastic shell to be molded, and the smoothness of the inner surface of the preset injection mold is within a preset range.

In this embodiment, the preset injection mold can be molded in advance according to the size and appearance shape of the transparent plastic shell to be formed, and further, the inner surface finish of the molded injection mold should be within the preset Within the range, so as to ensure that the surface of the transparent plastic shell to be formed after demoulding is smooth and transparent.

For example, the smoothness of the inner surface of the injection mold can be adjusted through a polishing process. For example, the inner surface of the preset injection mold can be finely ground or ground until the roughness of the inner surface is below 0.2, so that the inner surface reaches a mirror surface Or, chemical polishing can also be used to adjust the roughness of the inner surface of the injection mold; another example can be used to polish the inner surface of the injection mold, which is not limited by the present disclosure. Wherein, the transparent plastic in the pre-set injection mold may include fully transparent plastic, translucent plastic with a preset color, or other plastics with different degrees of transparency, which is not limited by the present disclosure.
