Electroplating gold vs. PVD gold plating
In the jewelry industry, the gold plating process is the core technology that endows stainless steel jewelry with a luxurious texture. There are essential differences between the two mainstream processes of electroplating gold and PVD gold plating.
Electro-gold plating
Through electrolytic reaction, gold ions are deposited on the surface of stainless steel. Cyanide-containing or cyanide-free electroplating solutions are required, with a thickness of 0.05-0.3 microns. They are soft and easy to polish, and can achieve multi-color effects such as 18K gold and rose gold.
PVD gold plating
In a vacuum environment, high-energy particles bombard gold targets, causing gold atoms to splash and adhere to the surface of jewelry.
The thickness is 0.1-0.5 microns, and the hardness is three times that of ordinary gold, but the color is mainly single pure gold.
PVD gold plating
It will not oxidize or peel off for more than 5 years
In terms of environmental protection, cyanide wastewater needs to be treated to achieve zero pollution and comply with the EU REACH regulation
It is suitable for high-end light luxury, medical-grade jewelry, etc
PVD gold plating (resistant to sweat corrosion and environmentally friendly certification) is a must-have for the high-end markets in Europe and America.
Electroplated gold plating offers a higher cost performance for the affordable market in Southeast Asia
The debate between electroplating and PVD plating is essentially a game of short-term costs and long-term value.
In the future, as EU environmental regulations (such as the New Battery Act to be implemented in 2024) tighten, PVD gold plating will become a “mandatory pass” for stainless steel jewelry to go global. Your choice will determine your position in the industrial chain for the next five years.
