Some time ago, in the production process of bright tin plating of a batch of precision hardware, the coating always appeared foggy and not bright.The brightener supplier did not solve the problem after processing the plating solution, which seriously affected the appearance and performance of the workpiece, and the customer did not accept it.This gave Mr. Zhang a headache, so he wanted to replace a better-performing sulfate tin plating brightener.
Recently, Mr. Lin always has the phenomenon of blistering in the coating of the workpiece after using the alkaline zinc-nickel alloy additive.So Mr. Lin wanted to find an alkaline zinc-nickel alloy additive that is not easy to foam.
Mr. Fu is the owner of an electroless nickel plating factory in Xingtai, Hebei Province.Some time ago, Mr. Fu's customer sent a batch of pasta machine parts to be plated with medium phosphorus chemical nickel, but these parts were complained and returned because of the poor wear resistance of the coating and always failed to meet the performance requirements the customer wanted.Mr. Fu didn't want to lose this big customer, so he wanted to find an electroless nickel plating solution with good wear resistance.
In our daily production process, some large workpieces or workpieces with complex shapes will cause uneven thickness of the coating due to uneven current distribution during the process of nickel electroplating.At this time, we can use this medium phosphorus electroless nickel plating additive to solve the problem of uneven thickness of the coating.
During this time, Mr. Hu used a matte tin additive introduced by a friend, but the production requires a large current density (other process parameters are normal), and the coating of the workpiece is relatively rough, loose, and brittle.This seriously affects the performance requirements of this USB plug-in.
Mr. Shen is the owner of an electroless nickel electroplating factory in Nantong, Jiangsu.Some time ago, due to the poor corrosion resistance and wear resistance of the workpiece coating after one of the customer's automotive switch parts was plated with medium-phosphorus chemical nickel, the workpiece had a short service life and was always complained by customers.So Mr. Shen wanted to find a medium-phosphorus electroless nickel plating solution with good corrosion resistance and wear resistance of the coating.
