Problems solved by technology

[0002] With the continuous progress of society and the continuous development of science and technology, people's quality of life is also rising. In daily life, portable electronic products are one of the necessities for people to go out, such as tablet computers and mobile phones. In order to improve its aesthetics, the shells of such electronic products need to have a certain degree of glass permeability, ceramic texture, and metal effects. On the other hand, in order to meet the portability and usability, they cannot directly use glass or Ceramics are used as the shell, so it needs to be coated with glass permeability and ceramic texture on the non-glass and ceramic shells. Most of the surface of the workpiece needs to be laser-engraved or printed with corresponding trademarks, words or patterns. Or printing requires additional equipment and processes, increasing complexity and increasing production costs

Abstract

The invention relates to the technical field of surface coating, in particular to a PVD coating technology. The PVD coating technology comprises the following technology steps that firstly, vacuum plating of UV primer is conducted on the surface of a workpiece; secondly, after plating of UV primer is finished, plating of the needed color is conducted through PVD magnetic control ion sputtering; thirdly, the needed position of a clad layer finished in the second step is shielded through ink; fourthly, after the third step is finished, plating of the needed color is conducted again through PVD magnetic control ion sputtering; fifthly, after the fourth step is finished, a cleaning agent is used for cleaning or thoroughly wiping the place shielded by the ink in the third step; and sixthly, after the fifth step is finished, highlight PU or UV protection finishing coat is sprayed to the surface of the workpiece. A traditional 3D laser carving technology is replaced by improving technology steps, complex procedures in actual production are reduced, the production efficiency is improved, the production cost is reduced as well, and practicability is high.
