Embodiment Construction

[0022] For having further understanding to the object of the present invention, method step and effect, now in conjunction with accompanying drawing, describe in detail as follows:

[0023] see figure 1 Shown, the manufacturing method of plastic case of the present invention, it comprises the following steps:

[0024] Step 110: Provide a high-temperature resistant film, and pre-bake the high-temperature-resistant film. The formed product plays a reinforcing role, and the thickness of the high temperature resistant film is 0.08mm ~ 0.30mm. The high temperature resistant film can be nylon PA4T, PA6T or PA9T. The high temperature resistant film can be treated with various textures according to requirements;

[0025] Step 120: screen printing ink layer on the high temperature resistant film to form an IMF film, and bake the IMF film after printing the ink layer, the ink layer can be directly a transparent hardened layer, or various according to customer needs Color pattern layer...

Abstract

A plastic housing manufacturing method and a product thereof. The method comprises the following steps: (1) providing a high temperature resistant film, performing punching positioning of the high temperature resistant film; (2) performing silk-screen printing of a printing ink layer on the high temperature resistant film to form an IMF film; (3) performing high-pressure molding of the IMF film; (4) punching the IMF film after high-pressure molding; (5) putting the punched IMF film in an injection mold, performing injection molding of high-rigidity plastics, and allowing the IMF film to be subjected to transfer printing to the surface of the high-rigidity plastic product during injection molding. The plastic housing product is a product manufactured by the plastic housing manufacturing method.

Description

【Technical field】 [0001] The invention relates to a method for making a plastic shell and its product, in particular to a method for making a plastic shell using a high-strength and high-temperature-resistant in-mold decorative film and its product. 【Background technique】 [0002] At present, the development trend of 3C products (electronic products, communication products, consumer products) is to develop in the direction of thinning, light weight and toughness. [0003] IMD (In Mold Decoration, in-mold decoration) technology is currently a popular surface decoration technology in the world. Its surface is a hardened transparent film, the middle is a printed pattern layer, and the back is an injection layer. Because the ink is in the middle, the product can prevent the surface from being scratched. Flowers and meet the needs of friction resistance, and can keep the color bright and not easy to fade. IMF (In Mold Film, in-mold film insert injection molding) is a technology ...
