Preparation method of IMT decorative part

Abstract

The invention relates to a preparation method of an IMT decorative part. The preparation method comprises the following steps: preparing a film, and forming an enhancer layer and a release-type coating layer on the surface of the film of a first coiling roll from top to bottom; carrying out UV transfer printing process, and forming a UV transfer printing layer on the enhancer layer of the film of the first coiling roller; carrying out primary vacuum electroplating processing, and forming a first vacuum plating film layer on the UV transfer printing layer of the film of a second coiling roll; carrying out the secondary vacuum electroplating processing, and forming a second vacuum plating film layer on the first vacuum plating film layer of the film of a third coiling roll; printing a pattern layer, and forming a pattern layer on the second vacuum plating film layer of the film of a fourth coiling roll; and injection molding, and forming an injection molding layer on the pattern layer of the film of a fifth coiling roll. Compared with the prior art, by adopting integrally-coiling operation, only the coiling rolls need to be transported in the entire process, the labor intensity is small, the working efficiency is high, the flatness is good, the injection molded decorative part can be well matched with an electronic product and is easy to assemble, and no gap is formed.

Description

technical field [0001] The invention relates to a production process of an electronic product and a decorative part of a household appliance, in particular to a preparation method of an IMT decorative part. Background technique [0002] IML technology: Chinese name: in-mold transfer printing technology. Its specific structure is a transparent film on the surface, a pattern layer in the middle, and an injection layer on the back. Because the pattern layer is in the middle, it can make the product resistant to friction, prevent the surface from being scratched, and can last for a long time. Keep the color bright and not easy to fade. It is widely used in the production and processing of mobile phone casings, air conditioner casings, computer casings and other electrical product casings. [0003] The existing IML process: cutting the existing roll film into a square block with a designed size, doing UV transfer embossing on one side of the cut film square block, and putting the...

Problems solved by technology

This kind of IML production process needs to cut the rolled film into several sheets, and process several sheets, so that the overall work efficiency is low, and the workers need to pick up the sheets during the processing process. Workers have a lot of labor. At the same time, the flatness of the ultra-thin parts formed by this process (that is, the ultra-thin parts are IML decorative parts with a thickness within 1.0MM) can only reach 1.5MM-3MM, and the super-large pieces (that is, this Oversized parts are IML decorative parts with a length of more than 1.5M) with a flatness of 2CM-5CM, and the flatness of the IML decorative parts is poor and cannot meet the design requirements, resulting in difficult assembly and gaps in the product, which affect the appearance
