Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Electrolytic degreasing powder is a chemical agent used in industrial production to remove grease and other impurities from metal surfaces, mainly by electrolysis. The following factors should be considered when selecting a suitable electrolytic degreasing powder:
Choosing the right passivator is essential to improve salt spray resistance. Bigely zinc-nickel alloys blue passivator Zn-323, performs well in practical applications. In the Neutral Salt Spray Accelerated Corrosion Test (NSS), Zn-323 showed white rust for more than 240 hours and red rust for more than 1,000 hours. It was able to provide protection for a longer period of time. The use of Zn-323 passivate can form a dense and non-porous passivation film on the surface of the plated layer, effectively blocking the intrusion of corrosive media and thus improving the salt spray resistance of the plated layer.
After we perform palladium activation in the plastic plating process, we also need plastic plating accelerator. What is plastic plating accelerator and why is Bigely plastic plating accelerator PL-6A suitable for you?
Electroless copper plating is a process in which copper ions are reduced by reducing agent and deposited on the surface of conductive substrate without current. The brightness of the coating is one of the important indexes to measure its quality. In order to achieve high brightness of the coating, the choice of additives is very important. The MID rapid electroless copper plating additive HS-ECu-801 developed by Bigely has become the ideal choice for many electroplating plants to pursue high brightness coatings due to its good performance.
Today we would like to introduce you to a very good cyanide-free alkaline zinc additive, Bigely BZ-515, which adopts the latest developed technology, not only obtains a uniform and bright appearance of the coating, but also has excellent equalizing and covering ability, and it is suitable for complex shapes or large flat workpieces, with balanced thicknesses in high and low zones. It is suitable for complex shapes or large flat workpieces with balanced thickness in high and low zones. In addition, it has the following characteristics:
When methanesulfonic acid tin plating additive is used, the acidity of the plating solution is relatively low, and the corrosion is relatively small. In the use of methylsulfonic acid tin plating additives, we can understand the advantages and disadvantages of additives through performance tests. The following takes the methylsulfonic acid tin plating additive Sn-819 from Bigely Technology as an example to conduct a performance test:
