Product spray coating process

Abstract

The invention discloses a product spray coating process, and belongs to the technical field of product manufacturing. The process comprises the following steps of spraying and coating an LDS treatment agent on a preset surface of a product; spraying and coating a polishing layer on the surface of the LDS treatment agent, and performing online baking, wherein the adhesive force between the preset surface of the product and the polishing layer is increased through the LDS treatment agent; performing polishing treatment on the polishing layer on the product, and enabling the thickness of the polished polishing layer to be smaller than a half of the thickness of the polishing layer before polishing; spraying and coating colored paint on the surface of the polishing layer; and spraying and coating finish paint on the surface of the colored paint. According to the product spray coating process provided by the invention, the subsequent treatment of the product treated by the LDS process can be realized, so that the roughness of the product obtained after treatment is low, and the appearance requirement can be further met.

Description

technical field [0001] The invention relates to the technical field of product manufacturing, in particular to a product spraying process. Background technique [0002] Laser Direct Structuring (LDS) refers to using a computer to control the movement of the laser according to the trajectory of the conductive pattern, projecting the laser onto the molded three-dimensional plastic device, and activating the circuit within a few seconds. pattern. Moreover, the LDS process has the advantages of flexible design, space saving, quick manufacturing, and high cost performance, and is widely used in mobile phone antennas, automotive electronic circuits, smart watches, camera packaging, aerospace, medical hearing aids and other fields. [0003] The LDS process includes the following steps: preparing raw materials, then injecting the raw materials into supports, activating and metallizing the supports by laser, and finally assembling the supports into electronic products. In the prior...

Problems solved by technology

However, the surface of the product processed by the LDS process is relatively rough. Therefore, the processed product needs to be treated, and there are few effective treatment methods in the prior art. Therefore, a product spraying process is urgently needed to deal with the product processed by LDS. After the product is obtained, so that the product meets the appearance requirements
