A customer inquired that during the production process of electroless nickel phosphorus alloy plating on hardware, the stability of the plating solution may fluctuate due to different workpieces produced, resulting in a decrease in the service life of the plating solution. So what methods do we have in the production process that can effectively extend the service life of the plating solution?
Based on on-site experience and the characteristics of Ni-809 as an additive for electroless nickel phosphorus alloy plating, Bigley Technology has analyzed the following six methods to effectively extend the service life of the plating solution:
1. Before production, it is necessary to analyze and adjust the plating solution every day, and conduct trial plating to ensure that the plating solution is in good condition before mass production can begin.
2. In order to remove harmful particles from the plating solution, the plating solution should be kept in circulation and filtered during the production process. When the plating solution stops electroplating before work, the filter element should be inspected and replaced or the groove should be reversed for treatment.
3. During the production process, the workpiece with the groove should be salvaged in a timely manner, as the workpiece will continuously deposit a nickel phosphorus alloy coating in the plating solution, which will affect the stability of the plating solution.
4. Each batch of workpieces can be removed from a small batch during production and placed in a plating bath, facilitating the accurate testing of the time and deposition thickness of the workpieces. The coating thickness of the workpiece can be determined by the deposition rate and electroplating time of the workpiece.
5. After entering the groove, the workpiece should be shaken evenly and should not touch or collide. For workpieces with blind holes, the blind holes should be facing upwards to promote the discharge of bubbles; Cylindrical workpieces should be hung vertically to avoid bubbles or impurities staying on the surface of the workpiece, resulting in pinholes and burrs.
6. The carrying capacity of the plating solution is generally 1-2dm2/L. During production, the number of workpieces should be determined based on the size of the workpiece and the volume of the plating solution to avoid excessive loading of workpieces into the groove, which can seriously affect the stability of the plating solution and lead to early scrapping of the plating solution.
So, in the production process of electroless nickel phosphorus alloy plating on our hardware, we can effectively extend the service life of the plating solution and reduce production costs through the above six points.
