In the production process of using nickel plating brightener, sometimes the adhesion of the nickel plating layer is poor and easy to peel, which may not be a problem of the plating solution. It is also necessary to check the rectifier, because the failure of the rectifier will also affect the adhesion of the nickel plating layer.
Hu is always the boss of a bright nickel plating factory for daily hardware in Ningbo, Zhejiang Province.A few days ago, President Hu found that the nickel plated workpieces produced had poor adhesion, and some of them were peeling.President Hu thought that there was a problem with the use of nickel plating brightener, so he quickly turned to Bigolly's engineer to help solve the problem.
After the engineer rushed to the site, he analyzed the nickel plating solution and found that the concentration of each component, pH value, brightener concentration and other parameters of the plating solution were all correct.The engineer also checked the rectifier of the production line. Since the display screen of the rectifier was broken, President Hu did not adjust the parameters of the rectifier during production, but only carried out production according to the current parameters set previously.So the engineer used a multimeter to test whether the current of the rectifier was normal, and found that the current was very unstable and fluctuated greatly.
The engineer quickly told President Hu about the rectifier, suggested that President Hu repair the rectifier or replace it with a new one as soon as possible, and explained to President Hu that,Due to the rectifier failure, the current will be too high and too low, so that the nickel coating of the workpiece will produce different internal stress under such different current intensity, so the adhesion of the nickel coating will be poor and easy to peel.
Since Mr. Hu's rectifier has failed for many times and has no maintenance value, he replaced it with a new one.Now, President Hu has used this nickel plating brightener Ni-301 to produce hardware with uniform and dense nickel plating layer. There is no problem of poor bonding force. The failure rate of the product has decreased from 8% to less than 0.1%, greatly improving the production efficiency.
Therefore, in the production process of using nickel plating brightener, sometimes the adhesion of the nickel plating layer of the workpiece is poor, which is not necessarily a problem with the plating solution. We should pay attention to the inspection of the rectifier, timely remove the fault, and improve the production efficiency.If you are interested in nickel plating brightener, please contact the Bigolly customer service for free samples and detailed technical information!
