Embodiment Construction

[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0028] In some embodiments, an in-mold insert injection molding structure includes an optical film and an ink layer coated on the optical film, the optical film, the ink layer and the injection molding material are integrally injection-molded, the The optical film includes a laminated structure formed by alternately laminating resin films with a higher refractive index and resin films with a lower refractive index. The basic principle of the optical film of the present invention is to use the interference effect of light. When the light is incident on the film with a laminated structure alternately stacked with different refractive indices, a special optical effect will be produced, bringing a metal high mat...

Abstract

The invention discloses an IML (in molding label) structure which comprises an optical thin film and an ink layer, wherein the optical thin film is coated with the ink layer; the optical thin film, the ink layer and an injection molding material are formed into a whole through injection molding; and the optical thin film adopts a stacked structure formed by alternatively laminating a resin film with a higher refractive index and a resin film with a lower refractive index. The invention further discloses an injection molding method of the IML structure. The metallic high-matte decoration of a product can be realized through one-time injection molding, and a non-conductive and environment-friendly metallic surface treatment effect of a structural member of a casing of an electronic product is realized.

Description

technical field [0001] The invention relates to injection molding technology, in particular to an injection molding structure and an injection molding method of an in-mold insert. Background technique [0002] In the consumer electronics industry, metal effects are more and more favored by consumers, but the current plastic metal treatment process NCVM can only process full-gloss or full-matte effects. Those who feel that the grade is not enough. At present, the realization of plastic high matt mainly depends on the assembly of different materials after NCVM, so the process is complicated and there is an assembly gap. The IML (In Molding Label) process covers printing, high pressure molding, punching, injection molding and other processing procedures, and is applied to communication products, such as the decorative processing of molded mobile phone casings. The IML process forms the die by cutting the base material, flat printing, ink drying and fixing, punching positionin...
