Problems solved by technology

[0004] In addition, the traditional follow-up process generally has the following three disadvantages: 1. Secondary processing such as painting or electroplating is required, which increases costs and causes environmental pollution; 2. Decorative inks such as ink on the surface of the product The material is easy to be worn or scratched under long-term use, which will reduce the overall quality and appearance of the product; 3. Follow-up appearance decoration after injection molding will cause problems such as a decline in product qualification rate
[0008] However, embossing on the surface that already has a printed pattern will reduce the yield of the product and cause the surface pattern to be eroded or damaged

Embodiment Construction

[0020] see figure 1 , figure 1 Shown is a schematic diagram of a specific embodiment of an in-mold transfer printing device applying the manufacturing method of the appearance part of the present invention. Such as figure 1 As shown, the in-mold transfer printing equipment includes a first mold 31 , a film feeding roller 32 , a second mold 33 , a transfer film 35 and an injection unit 37 .

[0021] The first mold 31 has a mold cavity 38, and the surface 311 of the mold cavity 38 has a texture 311a, and the texture 311a is a pattern. In particular, the texture 311a does not specifically limit the size, style, depth, pattern, etc., and is completely defined by the designer.

[0022] The transfer film 35 may include a base layer and a transfer pattern 351 . The base layer can generally be made of polymer materials such as PC / PBT, but not limited thereto. The transfer pattern 351 is generally a pattern or text printed on the base layer by using ink or paint. In particular, t...

Abstract

The invention discloses a manufacturing method of an appearance part, comprising the following steps that: a first mold is provided, wherein the first mold is provided with a mold cavity, and then the surface of the mold cavity is provided with grains; then a second mold is provided, and then a trans-printing film is arranged between the first mold and the second mold; and finally, a trans-printing technique is executed so as to form the appearance part.

Description

technical field [0001] The invention relates to a method for manufacturing an appearance part, in particular to a method for manufacturing an appearance part in which texture is introduced into an in-mold transfer process. Background technique [0002] As far as many products are currently on the market, most of them use plastic as a raw material for the outer shell of their products. For example, such as the casing of the mobile phone, the casing of the mouse or the casing of the MP3 player and so on. Therefore, there are countless types of plastics used as product casings. [0003] Therefore, in order to increase the added value of products, the strategy often used by manufacturers is to change the shape, color or pattern of the product shell, thereby attracting consumers' desire to buy (for example, the imitation bamboo shell of a laptop or directly using bamboo to make computer casings, etc.). Generally speaking, for these plastic shells with special patterns, pattern...
