Double-sided blank glossy rear plate

Engineered as essential jewelry findings for premium stainless steel necklace pendants, Jiaye's double-sided blank glossy rear plate provides dermatologist-certified foundations for unlimited custom pendant creations, precision-milled from medical-grade 304L stainless steel (ASTM F138) with nickel release <0.02µg/cm²/week (EN 1811). Featuring dual diamond-microabraded mirror surfaces achieving 0.07µm gloss finish (ISO 1302), this reversible component enables seamless laser engraving, enamel filling, or micro-pave setting on either face – eliminating design constraints for truly unique custom pendant expressions while providing scratch-resistant bases for high-end stainless steel necklace pendants. The 1.2mm hardened profile withstands 80kg/cm² compression stress (ISO 6892-1) without warping, supporting oversized gemstone clusters, while plasma-enhanced PVD coatings (gold/rose/black) maintain ΔE<0.5 chromatic consistency through 500+ salt spray hours (ISO 9227), resisting electrochemical reactions with mixed-metal chains. Jiaye optimizes these jewelry findings for streamlined custom pendant manufacturing with laser-etched registration marks for precision alignment during robotic assembly, REACH-compliant lead-free construction (<0.003% heavy metals), and bulk RFID-tagged packs featuring instant QR-code customization files to accelerate stainless steel necklace pendants production.
