Problems solved by technology

[0002] The surface of the existing plastic mobile phone keys is made of transparent ABS, PC, PET and other plastic substrates, with low surface hardness and poor wear resistance.
Directly used as the outer surface, frequently pressed and rubbed directly, the surface will be scratched, stained, and dirty quickly, and the appearance will quickly become ugly, seriously affecting its aesthetics and use effect
In addition, the color is relatively single. Nowadays, people have higher requirements for personalization and pursuit of fashion. A single color cannot meet customers' needs for colorfulness.

Embodiment Construction

[0018] Set forth concrete implementation steps of the present invention below in conjunction with Fig. 1:

[0019] 1. Production of high-precision molds

[0020] Molds can be made according to customer product design requirements. Such as brushed pattern, CD pattern, mesh pattern, bright mist and other colors. The appearance design requirements of the product in this example are: a. CD grain effect on the back; b. high-gloss, high-gloss surface effect on the front; c. raised characters on the front. When designing the mold, the CD pattern effect is produced by electroforming on the back, and the high-gloss surface is polished after the characters are produced by EDM on the front to achieve a mirror effect.

[0021] 2. Precise injection molding blank

[0022] Before the injection molding process, the mold should be cleaned without oil or dirt. During the molding process, the injection molding parameters should be adjusted to form qualified products, and the surface should b...

Abstract

The present invention proposes a kind of manufacturing method of colorful plastic mobile phone button, comprises following process step: (1) the blank front of plastic mobile phone button is coated with wear-resistant layer: TiO2 or SiO2 or ZrO2 or Al2O3 or diamond film; (2) blank The back is coated with alternately superimposed color films of Ti3O5 and SiO2 or alternately superimposed color films of SiO2 and TiO2 or alternately superimposed color films of Ti3O5 and MgF2 or alternately superimposed color films of ZrO2 and SiO2 or alternately superimposed color films of ZrO2 and MgF2 (3) Print the required color ink on the back of the blank; (4) Process characters on the back of the blank. The back side of the blank is firstly plated with the alternately stacked color film layers, and then plated with Cr or Al or Sn single metal film layers. The invention proposes a method for manufacturing plastic mobile phone keys with a wear-resistant surface and magical colors. The color is produced by refracting or reflecting light of different wavelengths through the film layer through optical principles.

Description

technical field [0001] The invention relates to a method for manufacturing a plastic mobile phone key, in particular to a method for manufacturing a plastic mobile phone key with a wear-resistant surface and magical colors. Background technique [0002] The surface of the existing plastic mobile phone keys is plastic substrates such as transparent ABS, PC, PET, etc., and has low surface hardness and poor wear resistance. Directly used as the outer surface, frequently pressed and rubbed directly, the surface will be scratched, stained, and dirty quickly, and the appearance will quickly become ugly, seriously affecting its aesthetics and use effect. In addition, its color is relatively single. Nowadays, people have higher requirements for personalization and pursue fashion, and a single color cannot satisfy customers' needs for colorfulness. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, greatly impr...
