The Science of Long-Lasting Lustre Why Superior Plating Chemistry Prevents Premature Tarnishing
In the fashion jewellery market, a piece’s first impression is entirely determined by its surface radiance. Low-cost imitation jewellery frequently cuts corners using thin flash-plating without an adequate barrier layer, resulting in rapid tarnishing, greenish copper oxidation, and customer skin discoloration within weeks of purchase.
VM Imitation operates an automated in-house plating facility equipped with multi-stage ultrasonic degreasing tanks, high-purity chemical salts, and cathodic electrophoretic lacquer baking ovens. Our proprietary micro-gold electroplating formula deposits a dense, uniform anti-tarnish plating layer, sealed by an optically clear baked polymer coat that resists atmospheric humidity, body sweat, and cosmetic perfumes.

Our electroplating laboratories deliver four verified surface finish profiles calibrated for diverse international buyer preferences:
Four-Stage Pre-Treatment & Plating Route Controlled Chemical Deposition for Microscopic Adhesion
All assembled brass jewellery undergoes systematic mechanical and chemical pre-treatment before dipping into specialized electroplating baths:
- Step 1: Mechanical Magnetic Deburring: Assembled pieces are tumbled in automated magnetic pin machines using micro-steel pins to eliminate soldering flash and polish intricate filigree crevices.
- Step 2: Multi-Chamber Ultrasonic Degreasing: Ultrasonic soundwaves strip microscopic buffing compounds, flux residues, and handling oils in heated alkaline and acid neutralization baths.
- Step 3: Controlled Electro-Deposition: Components receive a dense copper/palladium barrier layer followed by automated immersion in micro-gold or rhodium baths under regulated voltage rectifiers.
- Step 4: Cathodic Lacquer & Oven Curing: Pieces pass through an electrophoretic bath depositing a microscopic transparent polymer seal, baked in dust-free curing ovens at 140°C for 30 minutes.
100% Manual Optical Audit Criteria Zero Tolerance for Discoloration, Loose Stones or Deformities
Before pieces enter counting and packaging, our quality control team inspects every single item under 5000K daylight simulation optics:
100% free of acid stains, dark spots, pinhole pits, flaking blisters, or polishing buffer burns.
Every Kundan collet, CZ crystal, and hanging bead is tactile-checked for zero stone rattle or loose claws.
Earring pairs are placed side-by-side to verify exact length, loop alignment, and identical plating shade.
Ear posts, clasps, and backplates are hand-tested for burr-free comfort and smooth locking action.
