Why In-House Plating Matters
When jewelry factories outsource plating, you face unpredictable lead times, inconsistent color from batch to batch, and limited ability to customize. At LAIYI, we own and operate Sanhetai Plating Technology — a dedicated plating facility within walking distance of our main factory.
Benefits for your brand:
- Faster turnaround: Plating starts the same day casting finishes — no shipping to a sub-contractor
- Color consistency: Our master plating technician controls every bath
- Custom finishes: Match a Pantone reference or your brand's signature color
- Lower minimums: Plate small batches economically (10-50 pieces)
- Full QC: XRF testing on every batch to verify plating thickness
