What is the cause of foaming of plastic electroplating products?
The reason is that the oil removal during electroplating is not complete.
Incomplete oil removal before electroplating can lead to the separation of the oil film and the plating solution, affecting the deposition of cations on the surface of the anion, and sometimes even hindering the plating. For electroplated parts, if there is a little oil film on the surface of the product, the adhesion of the coating is also very unreliable. Under the influence of some external factors, the coating will bubble or even fall off. Therefore, it is necessary to strictly follow the process in order to bring this situation to the surface.
What plastics can be electroplated?
ABS engineering plastics can be electroplated.
When ABS engineering plastics are applied to products with thin walls and complex shapes, they can maintain their excellent properties and the formability of materials composed of plastics and esters. The greater disadvantage of ABS engineering plastics is their large weight and poor thermal conductivity. Its molding temperature is between 240 and 265 degrees. The temperature is too high, ABS will decompose, the temperature is too low, PC liquidity is poor.
Will plastic parts conduct electricity after electroplating?
After the plastic is formed, the wax and oil are removed, that is, the wax and oil on the surface of the plastic are removed and then coarser. What is thickening? Roughening involves etching the surface of the plastic into pits smaller than the tip of a needle, then cleaning it with reduced hydrochloric acid, then cleaning it with liquid palladium, so that palladium ions enter those pits, and then chemical copper or chemical nickel is equivalent to the liquid metal, so that the plastic surface is equivalent to a thin layer of metal.
If it must be non-conductive, you can spray a coat of varnish, which is common in electroplating plants, or add a coat of electrophoresis to make it non-conductive.
How to electroplate ABS plastic
ABS plastic surface plating process is suitable for the formation of multiple heavy metal layers on the surface of plastic parts. The conductive medium is first formed on the surface of the plastic element, then at least one layer of chemical metal layer (such as chemical copper layer and chemical nickel layer) is formed on the surface of the plastic element by chemical plating, then the material characteristics of the surface of the plastic element are adjusted, and then at least one layer of electroplated metal layer (such as electroplated copper layer, electroplated nickel layer and electroplated chromium layer) is formed on the chemical metal by electroplating.
Therefore, this plastic surface plating process can not only achieve the purpose of local plating, but also make the electroplated metal layer have high structural strength and high conductivity, while maintaining the original characteristics of the plastic parts.
