Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] figure 1 A 3D pattern sheet according to one embodiment of the present invention is schematically shown.

[0020] The 3D pattern sheet 1 used in this kind of 3D pattern plastic casing processing technology includes a resin film layer 11 and a 3D-treated pattern layer 12. The resin film layer 11 of the 3D pattern sheet 1 is made of PVC resin, PET resin or PP resin. become. There is a grating 13 on the outer side of the resin film layer 11, and the grating 13 is formed by UV offset printing, extrusion molding or heat pressing. The grating 13 density of the resin film layer 11 of the 3D pattern sheet 1 is 70 lines, 75 lines, 90 lines, 100 lines, 161 lines or 200 lines. The pattern layer 12 is printed on the inside of the resin film layer 11 .

Abstract

The invention discloses a 3D pattern plastic shell processing technology, belonging to the shell processing technology. The processing technology comprises the steps of preheating, hot pressing, cutting, injection moulding and post-processing, wherein in the preheating step, a 3D pattern sheet is preheated by a hot press to realize a softening effect; in the hot pressing step, the softened 3D pattern sheet is subjected to hot forming by a hot press and to positioning shaping by a setting die to obtain a 3D pattern shell; in the cutting step, the scraps of the 3D pattern shell are cut and removed; in the injection moulding step, the 3D pattern shell is placed in an injection moulding die, and injection moulding is performed in the 3D pattern shell by an injection moulding machine to obtain a 3D pattern plastic shell; and in the post-processing step, the scraps of the 3D pattern plastic shell are cut. The 3D pattern plastic shell processing technology can finish 3D imaging on the whole surface of the plastic shell once.

Description

technical field [0001] The invention relates to a shell processing technology, in particular to a 3D pattern plastic shell processing technology. Background technique [0002] 3D imaging is widely used in various fields, especially on the plastic casing of products. In the prior art, 3D imaging can only be applied on a flat surface of a plastic casing, and it is difficult to realize 3D imaging on a non-flat plastic casing at one time, and the 3D visual effect is not good. Contents of the invention [0003] In order to solve the above problems, the present invention provides a 3D pattern plastic shell processing technology, which can complete 3D imaging on the entire surface of the plastic shell at one time. [0004] The technical solution adopted by the present invention is: a 3D pattern plastic shell processing technology, including preheating, hot pressing, cutting, injection molding and post-processing; [0005] Preheating, preheating the 3D pattern sheet throu...
