Production method of IML face shell with magnetic printing ink stereo pattern effect

Abstract

The invention provides a production method of an IML face shell with a magnetic printing ink stereo pattern effect. The production method comprises the following steps: carrying out dust removal, heating and preshrinking processing to a transparent film; printing a color tracking and positioning color batch on the back surface of the transparent film through a screen printing machine; printing the magnetic printing ink on the back surface of the transparent film through the screen printing machine; carrying out pattern magnetized setting on the magnetic printing ink to form a magnetic printing ink stereo pattern layer; performing curing and drying; performing screen printing on an IML printing ink layer on the back surface of the magnetic printing ink stereo pattern layer; forming through injection molding. Therefore, the production method breaks through a traditional production process form of the IML face shell, the IML face shell is viewed from the transparent film layer, and the magnetic printing ink stereo pattern layer can show luster with light and shade contrast and the stereo effects of multiple layers and uniform transition, can bring strong visual impact to people, and only a magnetic printing ink printing line is increased on the conventional IML printing production line. Compared with the prior art, the production method is simple and efficient and high in practicability, and the produced IML face shell has a strong stereo effect.

Description

technical field [0001] The invention relates to the field of production technology of face shells of equipment such as communication electronics and household appliances, in particular to a production method of an IML face shell with a three-dimensional pattern effect based on magnetic ink. Background technique [0002] The surface shells of various communication electronics and household appliances in the market are mostly made of IML (in-mold insert injection molding) shells. The process is very remarkable. The surface is a layer of hardened transparent film, and the middle is a printed pattern layer. , the back is a plastic layer, the transparent film can prevent the surface of the product from being scratched and friction-resistant, and the pattern layer is sandwiched in the middle, which can keep the color bright and not easy to fade for a long time. This is what society needs. In order to enhance the appearance effect of the surface shell, it is usually to use screen ...

Problems solved by technology

In order to enhance the appearance effect of the surface shell, it is usually to use screen printing process or use UV varnish for repeated overlay printing to achieve the purpose of presenting the three-dimensional pattern effect, but such methods are very cumbersome in the actual production process, and the process The cycle is long, the production efficiency is low, and the practicability is insufficient, and the effect of the three-dimensional pattern printed in this way is not obvious. People need to stand at a close distance to see it, and the effect needs to be enhanced.

[0003] With the development of science and technology and the progress of society, the surface decoration of products is changing with each passing day, and consumers are becoming more and more picky about visual perception requirements. Traditional IML craft products can no longer meet the needs of consumers and the public, and more three-dimensional effects are urgently needed. At the same time as products with decorative effects, a simple and efficient production method for IML surface shells is also required
