The original color of stainless steel magnetic clasps is silver. Why do similar-looking products on the market come in different colors, such as black, gold, rose gold, and rainbow color?
This can be attributed to PVD coating technology, PVD coating is an advanced casting technology.
What is PVD Coating?
PVD coating stands for Physical Vapor Deposition coating. It’s a method of depositing thin films onto surfaces using physical processes like sputtering or evaporation in a vacuum environment.
Before starting the casting process, the air inside the vacuum casting machine is extracted to create a high vacuum environment. This removes gases and impurities, reducing the casting’s internal porosity and enhancing its density and uniformity.
Benefits of PVD Coating:
1:Enhanced durability: PVD coating significantly improves the durability of surfaces, making them more resistant to scratches, abrasion, and general wear and tear.
2:Superior hardness: The coating process increases the hardness of materials, enhancing their ability to withstand mechanical stress and extending their lifespan.
3:Excellent adhesion properties: PVD coatings adhere exceptionally well to the substrate, ensuring long-lasting performance without peeling or flaking, even under challenging conditions.
Why Choose PVD Coating on Stainless Steel Magnetic Clasp?
1:Environmental Friendliness
PVD (Physical Vapor Deposition) coating is an environmentally friendly process. Unlike traditional electrocoating methods, PVD coating produces minimal hazardous water waste and avoids the use of harmful chemicals like hexavalent chromium. This significantly reduces the environmental impact and potential health risks associated with coating processes.
2:Material Benefits
PVD coating is often used for depositing metallic coatings, such as titanium nitride (TiN), stainless steel, chrome, or aluminum. With the vacuum pressure casting furnace attracted widespread attention, more and more stainless steel magnetic clasp manufacturers utilize PVD coating to process the surface of the clasps.
3:Cost-Effectiveness
Although the initial cost of PVD coating equipment is higher, the long-term savings are substantial, PVD-coated stainless steel magnetic clasps require less maintenance and replacement due to their improved durability.
4:Anti-Oxidation
PVD coating ensures magnetic clasp has long-lasting color retention and corrosion resistance.
Overall, PVD coating provides a variety of color options for magnetic jewelry clasps at a lower cost, catering to diverse designs and tastes.
