Electroplating process management is an important link in electroplating production. It is determined that electroplating workers have obtained tens of millions of repeated experiments and studies, so the electroplating process is very scientific. The determination of the process not only considers the deposition speed of the coating, the current efficiency of the cathode, the dissolution of the copper removal agent and the balance of the deposition, but also the stability of the pH value, the wide range of temperature and current density, and the speed of light extraction, leveling performance, The brightness range and other aspects are comprehensively formulated. Therefore, we must pay full attention to the various technical parameters specified in the process, and cannot guarantee that only in this way can a good coating be formed. How to strengthen electroplating process management? The following is your introduction:

Pretreatment Plating pretreatment is the basis of electroplating quality. The treatment before electroplating is not good, the plating layer is not blooming, but doubles as bubbles, shelling, and even discarded defective products of both. The pretreatment of electroplating is mainly to remove oil stains, scale and rust on the electroplating materials. As a result, it is possible to ensure a good bonding force between the substrate and the plating layer, accelerate the deposition rate of the plating layer, and the plating solution will not be contaminated by the oil stains of the plated parts and foreign metal impurities. If there is a galvanizing manufacturer, large blisters and burrs are found on the coating after galvanizing, so repeated adjustments to the electroplating solution cannot solve the problem

If the workpiece enters the groove, there is a gel-like substance attached to the surface. This is because the rubber lining the container with concentrated sulfuric acid dissolves and adheres to the surface of the workpiece and cannot be cleaned. Therefore, it is recommended that the pretreatment must be degreasing and rust removal in accordance with the process regulations, and the surface state of the workpiece must be observed. Electroplating pretreatment includes ultrasonic removal, copper removal agent removal, pickling to remove scale and rust. It is necessary to analyze the composition of the degreasing and derusting liquid regularly and supply it regularly. The alkali tank must be filtered regularly, and the acid tank must be exposed regularly. Keep the degreasing and derusting liquid in good condition to ensure the quality of electroplating.
