Embodiment Construction

[0045] A method for manufacturing a luminous vehicle logo mask, comprising the following steps:

[0046] Step 1. Set an ink pattern layer by screen printing on the IML diaphragm, plate a nano-metal coating by PVD vacuum sputtering method, and set an astigmatism ink layer by screen printing; the ink pattern layer is the same as the pattern of the car logo of the main engine factory;

[0047] The IML diaphragm is divided into A and B surfaces, the A surface is the bonding surface with the mask injection molding material, and the B surface is the exposed surface;

[0048] The process sequence of the ink pattern layer, the nano-metal coating and the astigmatism ink layer includes the following six schemes:

[0049] Such as figure 1 As shown, the process sequence of the IML diaphragm 1 with ink pattern layer 2, nano-metal coating 3 and astigmatism ink layer 4 produced by scheme 1 is as follows: first, nano-metal coating 3 is plated on surface B, and then Screen printing ink patte...

Abstract

The invention provides a manufacturing method of a light-emitting vehicle logo mask, and the core lies in that a nano metal coating, an ink pattern layer and a light-scattering ink layer/light-scattering paint layer are integrated and realized on a membrane adopted in IML (in-mold insert injection molding); then the lampshade is subjected to injection molding through a mold, so the length of a process route is shortened, the product percent of pass is improved, and the production and manufacturing cost is reduced; on the other hand, the light scattering paint can replace a traditional light uniformizing piece or a light guide plate, the light scattering effect of the light scattering paint is better than that of the light uniformizing piece or the light guide plate, the space thickness of a light-emitting label system can be reduced through the light scattering paint, and the compact design of the system is achieved.

Description

technical field [0001] The invention belongs to the technical field of luminous vehicle logos, and in particular relates to a manufacturing method of a luminous vehicle logo mask. Background technique [0002] Signage is an indispensable part of automobile exterior decoration. Its function is to achieve the appearance decoration effect and improve the recognition of automobile brand. However, traditional signs cannot achieve such functions at night, so the demand for luminous signs has become an inevitable trend in the development of the automotive industry. [0003] At present, for luminous signs with the appearance effect of metal coating, the mask process is usually to inject the mask first and then apply PVD sputtering metal layer to the injection molded parts. In addition, the luminous signage system usually uses a dodging sheet or a light guide plate to achieve a dodging effect. The system process path is complex, resulting in a low yield and increased system cost. ...
