The electroplating process is a method of applying a layer of metal to a conductor using the principle of electrolysis. It refers to the use of electroplating in a salt solution containing a pre-plated metal as the cathode, and through electrolysis, the pre-plating metal A surface processing method in which cations are deposited on the surface of the base metal to form a coating.
In the process of plastic electroplating, it is used for many processes, and slight careless operation or inspection may cause product defects. The following are the causes of common defects, I hope to help everyone.
Reason: The surface of the plastic is broken or marked, which causes the residual moisture in the plastic to enter the surface during the electroplating process and form cracks.
Reason: The plastic edge part protrudes due to the excess plastic or uncleanly falling from the mold, which becomes sharp during the molding process, which affects the appearance, and was only noticed after plating.
Reason: It may be caused by air bubbles generated between the metal deposition layers during the electroplating process, or it may be caused by the moisture contained in the plastic that causes the plastic and metal deposition layers to generate air bubbles. Need to cut open the blister test before identification.
4.Scratches and dents
Reason: Scratches and dents that are not immediately visible during molding or processing, enter their processes, or are caused by scratching the original part during processing. The depth of the scratch or dent can be used to determine whether the defect is shallow or in the substrate.
5, dry up
Cause: Caused when parts become too dry between metal deposits during the plating process. This situation can be avoided by careful process control.
Reason: The substrate is not completely immersed in the plating solution, or the surface of the substrate is contaminated. Ensure that the substrate is completely immersed and cleaned to reduce the occurrence of springboards.
