Mr. Pan from Xiamen, Fujian is the owner of an electroless nickel electroplating factory.Recently, in the process of using medium phosphorus electroless nickel plating solution, Mr. Pan found that the deep plating ability of the deep hole workpiece coating is relatively poor, which affects the performance requirements of the workpiece.So Mr. Pan asked Bigolly engineers whether this electroless nickel plating solution was not easy to use.
After inspecting Mr. Pan's production line, the engineer found that most of the workpieces were workpieces with blind holes or deep holes.These workpieces will have low oil residues in the holes after die casting, and the simple pretreatment process cannot completely remove these oil stains, resulting in the deposition of the coating layer after the use of electroless nickel plating solution.
Therefore, the engineer gave Mr. Pan three suggestions:1. Strengthen the pretreatment degreasing process, increase the concentration of the degreasing fluid or increase the temperature, and improve the degreasing effect of the degreasing fluid.2. Add the process of ultrasonic degreasing and cleaning, which can better remove the oil stains in the deep holes or blind holes of the workpiece.3. In the process of electroless nickel plating, the hole of the workpiece should be facing up.In this way, the plating solution in the hole can be replaced in time, and the reacted gas can also be discharged in time, which can ensure that the electroless nickel coating can also be deposited normally in the blind hole or the deep hole.
Mr. Pan took the engineer's suggestion and optimized these 3 places.Now the blind holes and deep holes of Mr. Pan's workpieces can be deposited with electroless nickel plating, the deep plating ability is greatly improved, and the production efficiency is increased by more than 10%.
Therefore, after electroless nickel plating of workpieces with blind holes or deep holes, the deep plating ability of the coating is not necessarily because this electroless nickel plating solution is not easy to use. It is necessary to pay attention to the above three points, which can effectively improve production efficiency.If you are interested in electroless nickel plating solution, please contact Bigolly customer service to get free samples and detailed technical information!
