Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electroplating, and in particular to a product electroplating method for producing a matte effect. Background Art
[0002] Electroplating is a technique that deposits a layer of metal on the surface of an object through an electrolytic process. This technique is used to improve the corrosion resistance, wear resistance or aesthetics of an object. The basic principle is that the object to be plated is used as the cathode, and the metal ions are reduced from the electrolyte and deposited on the surface of the object, while the anode is the metal source. Common applications include decorative coatings, protective coatings, and improving mechanical properties.
[0003] There are two types of existing electroplating methods. One is direct electroplating of a single color, which can either be glossy or matte, and can only produce one brightness. The other is two-color electroplating, which uses ink to separate the required colors and then electroplating. The result is two colors. This is usually called color separation plating. These methods cannot achieve a double-layer glossy and matte effect on the product. Summary of the invention

[0011] Preferably, the laser matte treatment utilizes the high precision of the laser process and the principle that even tiny places can be lasered to laser the product to achieve a matte effect on the red copper plating layer.
[0012] Preferably, the secondary preparation includes hanging, secondary pretreatment and secondary activation; the hanging is to put the product on the product equipment; the secondary pretreatment is the same as the primary pretreatment and the secondary activation is the same as the primary activation operation.
