Problems solved by technology

However, in this case, since the wet method and the vacuum vapor deposition method are carried out in an alternate manner, it causes additional cost due to the use of different methods, and leads to the problem of defective products during transportation between different methods

[0007] That is, due to the introduction of the wet method, the wet method and the vacuum vapor deposition method (dry method) are carried out in an alternating manner, so the processing time for coating the part becomes longer because of the repetition of the process between the different methods. Mounting and dismounting of coated objects in transport and various methods

[0008] In addition, yield decreases due to processing rejects during different process runs and high reject rates during transport between different processes, as well as increased production time due to multiple processes. lead to high product production costs

[0009] Furthermore, such structural problems tend to be exacerbated when the company doing the wet coating is different from the company doing the vacuum vapor deposition

[0010] Additionally, if Figure 4 As shown, compared with the coating film 70 prepared by hundreds of thousands of vacuum vapor deposition processes (dry method), the coating film 60 prepared on the surface of the product 10 by the wet method is thicker, and due to the reduction of the visual properties of the substrate and the surface Deterioration of the texture, the unique properties of the substrate are not at their best
