Double-sided blank rear plate

Engineered as foundational jewelry findings for medical-grade bulk body jewelry stainless steel, Jiaye's double-sided blank rear plate delivers uncompromised water resistance through precision engineering, crafted from ASTM F138-certified 304L stainless steel with 0.015µg/cm²/week nickel release . Featuring dual diamond-microabraded surfaces achieving 0.06µm hydrophobic finishes, these plates eliminate fluid entrapment for true jewelry waterproof security in piercings and body applications, validated through 400+ hour salt spray tests and 100ATM hydrostatic pressure resistance . The reversible 1.5mm profile withstands compression stress  while maintaining electrochemical neutrality with sweat/pH fluids, and plasma-enhanced PVD coatings (gold/black/rose) extend jewelry waterproof integrity with  color retention through extended wear. Optimized for bulk body jewelry stainless steel production, integrated laser-etched solder grids enable robotic assembly of belly/nose/eyebrow jewelry, while REACH-compliant construction and submersible-ready tarnish barriers prevent microfissure corrosion. Jiaye accelerates jewelry findings integration with RFID-tagged sterile packs, autoclave-compatible packaging , and wholesale MOQ 100 units featuring Prop 65/CPSC certification for global body jewelry compliance.
