Problems solved by technology

However, since the material generally used for injection molding is Polycarbonate (PC), which is not wear-resistant, the shell produced by the above-mentioned injection molding technology is not only difficult to pass the hardness test of the product, but also the produced shell The thickness is relatively thick, and it cannot meet the requirements of thinning the shell
In addition, there is a relatively special film injection molding technology. Although the thickness of the casing produced by this injection method meets the requirements, the product produced by the above method has a low yield rate and high production costs.

Embodiment Construction

[0026] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments will be described in detail below together with the accompanying drawings.

[0027] figure 1 It is a flowchart of a method for manufacturing a patterned sheet according to an embodiment of the present invention. The patterned sheet of this embodiment is, for example, a thin key sheet for a mobile phone, and its manufacturing method includes the following steps: First, step S1 is performed to provide a substrate and form an adhesive medium layer on the first surface of the substrate. Then, step S2 is executed to provide a mold, and the mold is provided with a pattern. Next, step S3 is executed to set a plastic layer on the pattern of the mold. After the plastic layer is set on the pattern of the mold, step S4 is then performed, disposing the base material on the plastic layer, and pressing the base material and the plastic layer toge...

Abstract

The invention provides a preparation method of a patterned sheet, which comprises the following steps: firstly, a base material is provided and a viscous dielectric layer is formed on the surface of the base material. Then, a mould is provided, and the mould is provided with a pattern. A plastic layer is arranged on the pattern of the mould thereafter. And then, the base material is deployed on the plastic layer, and the base material and the plastic layer are pressed together, so that the base material and the plastic layer are tightly connected by a viscous dielectric layer. The mould is removed, so that a patterned plastic layer is formed on the base material.

Description

technical field [0001] The present invention relates to a method for manufacturing a patterned sheet, and in particular to a method for manufacturing a patterned sheet with a glare effect. Background technique [0002] With the advancement of technology, electronic products such as mobile phones have become indispensable communication devices in daily life. Generally, users will consider the functionality and appearance of the mobile phone when purchasing a mobile phone, and mobile phones with complete functions and dazzling appearance are also launched in the market in response to the needs of users. Generally speaking, in order to make the mobile phone have a more dazzling appearance, the casing of the mobile phone is usually provided with textures to have a better texture. For example, in the known technology, screen printing is used to form textures on the casing during the manufacturing process of the casing. However, although screen printing can form textures on the ...
