Double-sided blank glossy rear plate

Engineered as foundational jewelry findings for premium pendants stainless steel manufacturing, Jiaye's double-sided blank glossy rear plate delivers mirror-finish versatility across both surfaces, precision-machined from medical-grade 304L stainless steel  with nickel release under to ensure hypoallergenic security for direct-skin-contact jewelry stainless steel applications. Featuring dual diamond-microabraded planes achieving 0.08µm mirror gloss  without directional grain patterns, these plates enable seamless 360° visual continuity when embedding pendants stainless steel centerpieces while providing REACH-compliant lead-free solder pads on both sides – enabling reversible assembly flexibility crucial for high-yield jewelry stainless steel production lines. The hardened 1.2mm profile withstands 80kg/cm² compression stress  without deformation, supporting oversized gemstone settings, while plasma-enhanced PVD coatings (gold/rose/black) maintain color consistency through 400+ salt spray hours. Jiaye optimizes these jewelry findings for pendants stainless steel mass production with CNC-milled alignment notches preventing rotational slippage during automated soldering, pre-treated laser-etching surfaces for instant adhesive bonding, and bulk-packaged units featuring QR-coded certification for Prop 65/CPSC global compliance.
