The punching mesh, precision stretching stamping parts, mesh screens and other products after high-speed stamping processing are only the main materials, and only through electroplating can the value of the product be better reflected. The main purpose of electroplating is to prevent product oxidation, reduce contact impedance, increase soldering resistance, increase wear resistance, and improve service life.


Punching mesh electroplating is a method of applying a layer of coating on the surface layer and using electrode reactions to form a coating on the surface of precision stamped parts. The material (workpiece) with a conductive surface is used as the cathode, and the dissolved metal (Ni, Sn/Pb, etc.) is used as the anode. It is placed in an electrolyte solution, and under the action of external direct current, the anode metal dissolves into metal ions, which precipitate on the cathode (workpiece), forming a firmly bonded electroplating layer with the workpiece.


The inspection methods for coating mainly include: steel needle scratching or bending test, which mainly tests the adhesion of the coating; The X-Ray equipment is mainly used to inspect the thickness and composition of electroplating coatings; Visual inspection mainly refers to the inspection of appearance; Gelatin electrolysis test is mainly used for checking the porosity of coatings; SEM/EDX analysis is a method of analyzing pollutants to determine if they meet the standards.
