Shell and manufacturing process thereof

Abstract

The invention provides a shell and a manufacturing process which comprises the steps of base material manufacturing, color film manufacturing, attaching and CNC machining, and the step of base material manufacturing comprises the steps that adopting transparent plastic d in a mold subjected to polishing and fine carving texture treatment for injection molding of the base material; the step of color film manufacturing comprises the following steps: carrying out printing treatment on a PET film with optical cement, carrying out texture treatment on the PET film subjected to printing treatment, and carrying out coating treatment on the PET film subjected to texture treatment to obtain the color film; then attaching the base material and the color film to remove bubbles, and finally obtaining a finished product through CNC machining. The invention further provides a shell. According to the manufacturing process of the shell, the color texture and the touch flatness of the transparent plastic shell are improved, the smooth and matte integrated effect can be achieved, the shell has the richer visual effect, and the appearance competitiveness is greatly improved.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a casing and a manufacturing process thereof. Background technique [0002] With the development of electronic equipment such as mobile phones, the requirements for the appearance of products are gradually becoming higher. More and more battery covers made of glass have the same matte effect (meaning that in the same overall shape, the human eye can observe the matte effect in different areas. Gloss distinction; fingers can feel the difference between roughness and fineness in different areas), which is applied to high-end smartphone products, and is deeply loved by users, and the popularity continues to increase. During the process of conceiving and implementing this application, the inventors found at least the following problems: the battery cover made of glass has defects such as complicated processing technology, low manufacturing yield, and high cost. Based on ...

Problems solved by technology

During the process of conceiving and implementing this application, the inventors found at least the following problems: the battery cover made of glass has defects such as complicated processing technology, low manufacturing yield, and high cost. Based on the trend of mobile phone appearance, people will also choose to use PC. Materials to make the battery cover

[0003] In some implementations, the matte homogeneous process used on the PC material mobile phone battery cover cannot make the mobile phone have a beautiful appearance, and it still has a certain sense of difference compared with glass materials. The method of spraying on the surface can get the same fog effect. The thickness of the shell material obtained in this way must be more than 0.8mm, and the surface has uneven steps, which affects the hand feeling and the color rendering effect is not good. Pencil hardness can only reach ≥1F, resulting in low product appearance competitiveness
