Problems solved by technology

Since the metal film and the base layer of the case are made of different materials, the choice of the adhesive layer will determine whether the metal film can be stably coated on the case surface, and will inevitably increase the manufacturing cost in the production process

Embodiment Construction

[0019] The technical content of the present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0020] The present invention can be applied to various in-mold decoration (In-Mold Decoration, IMD) processes, including in-mold transfer printing (In Mold Roller, IMR), in-mold labeling (In Mold Label, IML) and in-mold forming ( InMold Forming, IMF), etc., especially in-mold transfer (IMR) technology.

[0021] see figure 1 , which is a schematic flow chart of the steps of an embodiment of the present invention, as shown in the figure: the present invention discloses a method for manufacturing an in-mold forming film with a metal surface, comprising steps:

[0022] a) providing a metal plate layer (S10): the metal plate layer has a joint surface and presets at least one etching region;

[0023] b) Applying an etching process (S20): performing an etching process on the etched area on the joint surface, and after ...

Abstract

A method for manufacturing an in mode forming film with a metal surface comprises the following steps: firstly, providing a metal plate layer which possesses a joint surface presetting at least one etching area; then, performing an etching operation on the etching area of the joint surface so that a plurality of depressed structures are inwardly formed on the etching area surface; after finishing etching the metal plate layer, ejecting plastic with an injection moulding pressure to the joint surface of the metal plate layer so that the plastic which is under an compression of the injection moulding pressure clads the depressed structures of the etching area; finally, bearing the metal plate layer after the plastic is solidified, wherein the solidified plastic forms a close bonding relationship with the depressed structures. Therefore, an adhesion layer doses not need to be additionally arranged between the metal plate layer and the ejected plastic. Manufacturing costs are saved and processing operations can be reduced during the making programs.

Description

technical field [0001] This invention relates to a method of making an in-mold formed film, and more particularly to a method of making an in-mold formed film having a metallic surface. Background technique [0002] With the trend of miniaturization and thinning of electronic products, many portable products, such as notebook computers, personal mobile assistants, mobile phones, etc., are widely used because they meet the needs of the general public. In addition to physical function, appearance design is also a very important consideration in business. [0003] The production of traditional plastic products is limited by the technology of plastic injection, which can only be used for single-color injection, and there is no change. If you want to give patterns or other color decorations to the plastic products, you can only apply the patterns on the surface of the casing by printing or spraying. Although the general printing process with high maturity is used, the cost is l...
