Problems solved by technology

[0002] Electroplating refers to a surface processing method in which the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal by electrolysis, using the base metal to be plated as the cathode in the salt solution of the pre-plated metal to form a coating. The performance of the coating is different from that of the base metal and has new features. According to the function of the coating, it is divided into protective coating, decorative coating and other functional coatings. However, in the electroplating process, there are peeling, peeling, pinholes, pitting, Spots, bubbling, blooming, poor corrosion resistance and other defects, thus reducing the quality of electroplating, for this reason, we propose a metal surface treatment electroplating processing method

Abstract

The invention discloses a metal surface treatment electroplating processing method. The metal surface treatment electroplating processing method comprises the following steps: A, oil removal, cleaning and drying treatment is carried out on the surface of a metal part; and B, cutting and grinding treatment is conducted on the metal part. In the step A, the metal part is put into an oil removal agent for oil removal treatment, then the metal part is put into a cleaning agent for cleaning treatment, finally the metal part is put into a drying box for drying treatment, the drying temperature is 80-100 DEG C, and the drying time is 3-8 minutes; and in the step B, the metal part is cut and ground through a machine tool, and the surface of the metal part is more neat. According to the metal surface treatment electroplating processing method, the surface of the metal part is subjected to oil removal, cleaning and drying treatment firstly, oil stains and other impurities on the surface of the metal part can be effectively removed, the metal part is cut and ground after being dried, and the surface neatness of the metal part can be effectively improved; and meanwhile, the metal part is rinsed after electroplating is completed, and redundant electroplating liquid on the surface of the metal part can be effectively rinsed, so that the electroplating quality of the metal part is effectively improved.
