[0014] Such as Figure 1As shown in the figure, the 3D stereoscopic automotive decorative part has a flat back surface, which is smooth and has no concave or convex structure. Its shape is one of a circle, an ellipse, a rectangle or a square, with a size length of 20 mm - 1500 mm; the depth H (from the lowest point to the highest point) of the concave surface is 0 mm - 150 mm. It mainly includes a material layer 100. The back surface of the material layer 100 has a PC / PET transparent film layer 300. There is an OCA optical adhesive layer 200 between the PC / PET transparent film layer 300 and the material layer 100. The OCA optical adhesive layer 200 is located on the back surface of the material layer 100, and the PC / PET transparent film layer 300 is located on the back surface of the OCA optical adhesive layer 200. Here, through the OCA optical adhesive layer 200, it is convenient to bond the PC / PET transparent film layer 300 to the back surface of the material layer 100. The OCA optical adhesive layer 200 can be selectively used according to different processes. The PC / PET transparent film layer 300 can also be selectively used according to different processes. On the back surface of the PC / PET transparent film layer 300, there is a 3D texture transfer layer 400. The 3D texture transfer layer 400 can be directly transferred onto the material according to different processes, and different 3D stereoscopic pattern effects can be selected, such as diamond, triangle, sphere, etc. On the back surface of the 3D texture transfer layer 400, there is a printing layer 500. The printing layer 500 can be selectively used with processes such as screen printing, offset printing, pad printing, etc. according to different processes. In order to protect the back surface of the entire automotive decorative part from scratches, there is a PVD coating layer 600 on the back surface of the printing layer 500. On the back surface of the PVD coating layer 600, there is a clear varnish protection layer 700. The PVD coating layer 600 and the clear varnish protection layer 700 can be selectively used or replaced by screen printing according to different processes. In order to protect the front surface of the automotive decorative part, there is a transparent protection layer 800 on the front surface of the material layer 100. Here, the transparent protection layer 800 can be selectively used according to different processes.

[0015] During production, first, the material layer 100 of the transparent optical plate part is injection-molded. The material of the material layer 100 can be transparent materials such as PC and PMMA. The decorative pattern of the product is laser-engraved on the optical plate. The engraving depth of the optical plate is 30 nm - 100 nm, and the specific depth is determined according to the decorative effect pattern. Then, the engraved texture pattern is copied into a production texture template. The copied production texture template is transferred onto the PC / PET transparent film layer 300 through a UV transfer machine and cured with UV glue. After curing, the texture film is then processed by screen printing to retain the 3D texture area through a masking and hollowing method. After screen printing, PVD indium plating is carried out to enhance the three-dimensional sense of the 3D texture pattern. After the 3D film is formed, it can be bonded to the material layer 100 of the transparent optical plate part, and the 3D stereoscopic pattern decorative effect of the entire decorative part is achieved.

[0016] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on what can be achieved by those of ordinary skill in the art.
