Why PVD Thickness Should Always Be Listed on Your Purchase Order
For experienced buyers sourcing 316L Stainless Steel Jewelry, PVD color alone is not enough. The coating thickness specified on your purchase order directly impacts durability, consistency, and quality verification throughout the supply chain.
1. Match Product Performance to Your Warranty Promise
Many manufacturers offer multiple PVD thickness options to balance cost and wear resistance.
Our standard high-performance specification is 0.5μm PVD coating, available in 14K gold, 18K gold, silver, black, champagne gold, and rose gold finishes. This thickness level supports our stated 2-year daily-wear warranty.
The coating consists of a titanium interlayer at 0.45 microns and an 18K gold PVD layer at 0.03–0.05 microns, with a total coating thickness of 0.5 microns. This layered structure helps enhance coating adhesion, wear resistance, and long-term color stability.
Without a written thickness requirement, thinner alternatives such as 0.03μm or 0.1μm may be used, creating a gap between expected durability and actual product performance.
2. Improve Batch-to-Batch Consistency
For Wholesale Jewelry, Private Label Jewelry, and large-scale OEM Jewelry Manufacturing, consistency matters.
A specified 0.5μm PVD layer allows factories to maintain stable vacuum deposition parameters, helping achieve uniform color, stronger adhesion, and reliable surface performance across repeat production runs.
3. Create Clear Quality Control Standards
Including PVD thickness on purchase orders establishes an objective inspection benchmark.
Using third-party XRF testing, buyers can verify that finished products meet agreed specifications before shipment. This reduces disputes, simplifies quality control, and supports long-term supplier relationships.
For brands purchasing Custom Jewelry, Stainless Steel Jewelry, or PVD Gold Jewelry, documenting coating thickness is a simple but effective step toward better quality consistency, clearer expectations, and stronger OEM cooperation.
