Embodiment Construction

[0017] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0018] The production process of bright and dumb homogeneous effect molded parts is processed through the following steps: The production technology of bright and dumb homogeneous effect molded parts is processed through the following steps:

[0019] Step 1. Injection molded workpieces are formed, using in-mold inserts to form injection molded parts with a plastic surface on one side and a non-plastic surface on the other side;

[0020] This injection molded part is preferably an IMT injection molded part. Specifically, a PET film is prepared first, and then a release layer is coated on one side of the PET film. After the treatment, a gradient color or a solid color treatment is carried out on the release guide. Form a gradient color or solid color color layer, print Logo on the color layer, and then perform UV...

Abstract

The invention provides a manufacturing process of a molded part with the glossy and matt integration effect. According to the manufacturing process, the molded part is machined through the following steps: 1, molding of an injection molded part; 2, high-gloss UV treatment: spraying a layer of high-gloss UV paint on a non-plastic surface of the injection molded part obtained in the step 1, whereinthe high-gloss UV paint is formed by mixing matt powder and high-gloss UV finish paint; 3, laser carving treatment: feeding a high-glossy part obtained in the step 2 into a carbon dioxide laser carving machine to conduct local laser carving machining to form a glossy and matt integration part; and 4, matt region treatment: coating a matt region of the glossy and matt integration part obtained in the step 3 with a layer of nanometer protective liquid for protective treatment to obtain the molded part with the glossy and matt integration effect. Compared with the prior art, the manufacturing process provided by the invention has the advantages that the injection molded part with the glossy and matt integration effect can be realized; the whole process is simple in manufacturing and low in cost; and moreover, the matt surface has the good hardness and wear resistance effect.

Description

technical field [0001] The invention relates to a manufacturing process of an in-mold injection molded part, in particular to a manufacturing process of a molded part capable of realizing the same body effect of a bright surface and a matte surface. Background technique [0002] Injection molding decoration technology of in-mold inserts is currently a popular surface decoration technology in the world. It is mainly used for decoration and functional control panels of home appliances, automobile dashboards, air-conditioning panels, mobile phone casings, lenses, washing machines, refrigerators, etc. It is widely used. With the evolution and development of the injection molding process of in-mold inserts, according to the different processes before and after in-mold injection molding, the injection molding technology of in-mold inserts can be formed into IML injection molded parts, IMD injection molded parts, IMF injection molded parts, IBF injection molded parts , IMT injectio...
