Dongguan precision technology electronics co. , LTD. Is a collection development, design, production, sales in the integration of professional stainless steel shrapnel manufacturing enterprises. Its products are widely used in household appliances, automobile, motorcycle, communication and computer, etc. The company has complete advanced equipment, high-quality technical personnel and high efficient management system, pay attention to the innovation of technology and service, can according to customer requirements, design and manufacture of the corresponding products, to solve the practical problems of customers, meet the demand of the differentiation of different customers. On stainless steel shrapnel in the process of traditional metal water electroplating processing in continuous nickel plating process, when the continuous nickel plating layer thickness is not enough or produce local did not prevent the continuous nickel plating on plating, plating method can be adopted. First the shrapnel anodization in the solution of the following: sulphuric acid added dose: 750 g /; Glycerol adding dosage: 60 g/L; Chromium anhydride added dose: 50 g/L; Oxalic acid added dose: l0g/L; Electroplating processing technological process of temperature control: l5 ~ 25 ℃; DA specific parameters: 0. 8 to 1. 2 a / dm2; In the process of electroplating time grasp: 4 ~ 7 s. After dealing with the solution of the workpiece, immediately in 1:3 hydrochloric acid leaching l ~ 3 s, primarily to wash out of chromic acid may be attached on the parts, then after wash, quickly in cyanide copper plating copper plating solution tank. DK specific parameters; 0. 1~O. 2 a / dm2; The accuracy of time: 5 ~ lOmin. After copper plating of stainless steel shrapnel again after washing, and soak 30 - 50 g/L of dilute sulphuric acid, washed immediately after the continuous nickel plating tank, according to the original process conditions for continuous nickel plating. The plating time can be determined according to the required thickness.
