Embodiment Construction

[0012] The following will clearly illustrate the spirit of the present invention with drawings and detailed descriptions. Anyone with ordinary knowledge in the technical field can change and modify the technology taught by the present invention after understanding the preferred embodiments of the present invention. without departing from the spirit and scope of the present invention.

[0013] Please refer to figure 1 , which shows a cross-sectional view of a preferred embodiment of the in-mold decoration injection molding shell of the present invention. A decorative film layer 110 and a plastic 120 are combined into an injection molded shell 100 using an in-mold decoration technique (In-Mold Decoration; IMD). The IMD injection molding casing 100 includes plastic 120, a first plastic layer 112, a graphite layer 114, and a second plastic layer 118 in sequence, wherein the first plastic layer 112, the graphite layer 114, and the second plastic layer Layer 118 is combined with t...

Abstract

The invention discloses an injection forming shell of decoration in dies, comprising a decoration film layer and plastic. The decoration film layer comprises a first plastic layer, a second plastic layer and a graphite layer; wherein, the graphite layer is arranged between the first plastic layer and the second plastic layer; the plastic can be combined with the decoration film layer as the injection forming shell of decoration in dies from the injection forming preparation process of decoration in dies. The invention also discloses an injection forming preparation method of decoration in dies.

Description

technical field [0001] The present invention relates to an injection molding casing and a manufacturing method thereof, in particular to an injection molding casing with in-mold decoration and a manufacturing method thereof. Background technique [0002] In-mold decoration technology (In-Mold Decoration; IMD) is an automated production process, which can be printed on the surface of the film, hot-pressed, punched, and finally combined with plastics. In-mold decoration technology can replace or reduce the surface appearance of plastic products, painting process or sticker processing, and increase the color and scratch resistance strength, so it is often used in high value-added plastic products, such as mobile phone panels, notebook computer casings, personal digital Assistant (Personal Digital Assistant; PDA) shell, automobile interior instrument panel, etc. [0003] Notebook casings often have local temperature unevenness due to internal heat-generating electronic componen...
