The metal stamping manufacturer teaches you how to inspect the metal after plating

Metal stamping manufacturer is a company specializing in the production and processing of electronic metal stamping parts, various small stamping parts and other products. The company has passed ISO9001-2015 certification and has a complete and scientific quality management system. The company's integrity, strength and product quality have been recognized by the industry. Friends from all walks of life are welcome to visit, guide and negotiate business. Scientific quality management system.

Products such as punching nets, precision drawing stamping parts, mesh screens, etc. after high-speed stamping are only the main materials, and the value of the products can be better reflected only after plating. The main purpose of electroplating is to prevent product oxidation, reduce contact resistance, increase solder resistance, increase wear resistance, and increase life.

Punching mesh electroplating is a method of applying a layer of plating on the surface, using electrode reaction to form a plating layer on the surface of precision stamping parts. The material (workpiece) with a conductive surface is used as a cathode to dissolve metals (Ni, Sn/Pb, etc.) As an anode, it is placed in an electrolyte solution. Under the action of external direct current, the anode metal is dissolved into metal ions and precipitated on the cathode (workpiece), thereby forming an electroplated layer firmly combined with the workpiece.

The inspection methods of the coating mainly include: steel needle grid or bending test, this inspection method is mainly to test the adhesion of the coating; the X-Ray equipment mainly inspects the thickness and composition of the electroplating coating; the visual inspection is mainly for the appearance inspection ; Gelatin electrolysis test is mainly used to test the porosity of the coating; SEM/EDX analysis is to test the analysis of pollutants, and it is not up to the standard.
