Problems solved by technology

However, an electrostatic effect will be generated when the protective film 120 is torn off, and impurities and foreign matter will be adsorbed on the reinforcement layer 116 of the forming film 110. Layer 116 causes damage, which reduces the yield
Moreover, even if the cleaning procedure is carried out in advance, it cannot be guaranteed to be clean, and the cleaning time will be increased

Embodiment Construction

[0016] see Figure 2A , Figure 2B , Figure 2C , Figure 2D , Figure 2E , Figure 2A to Figure 2E What is shown is a schematic diagram of the molding method of the in-mold decoration in this embodiment. Please refer to Figure 2A Firstly, a formed film 210 is provided. The formed film 210 includes a substrate layer 214 , an ink pattern 212 and a reinforcement layer 216 . The substrate layer 214 is located between the ink pattern 212 and the reinforcement layer 216 . Wherein, the material of the strengthening layer 216 can be acrylic, and the material of the base layer 214 is selected from the group consisting of polycarbonate, polyethylene terephthalate, ABS resin and polyvinyl chloride resin. Any one, wherein the ABS resin is an acrylonitrile-styrene-butadiene copolymer, and ABS is the acronym for Acrylonitrile Butadiene Styrene. In addition, the composition of the ink pattern 212 may also include polycarbonate or acrylic in addition to the colorant. In addition, the ...

Abstract

The invention relates to a shaping method for an in-mold decoration, which comprises the following steps: firstly, providing a shaped thin film which comprises a base material layer, a printing ink pattern and a reinforcement layer; secondly, arranging a protective film which can resist high temperature on the reinforcement layer; and thirdly, conducting the pre-press shaping step for the shaped thin film and the protective film. The base material layer is positioned between the printing ink layer and the reinforcement layer. The shaping method can prevent external foreign matters from damaging the reinforcement layer during the pre-press shaping process.

Description

technical field [0001] The invention relates to an in-mold decoration forming method, in particular to an in-mold decoration forming method in which a protective film and a formed film are pre-pressed and formed together. Background technique [0002] In Mold Decoration (commonly known as: IMD) is a relatively new production technology. Compared with other production technologies, In Mold Decoration can simplify the production steps, so it can save time and cost for rapid production. At the same time, in-mold decoration also has the advantages of increasing the complexity of the image and improving product durability. The in-mold decoration process is mainly to apply ink printing, preforming, and trimming to the surface of the formed film, and finally combine it with plastic to form it, eliminating the need for secondary operations and man-hours. Especially in situations where backlighting, multi-curved surfaces, metal imitation and other printing and painting processes can...
