Manufacturing Protocol
The OEM & ODM Jewelry Engineering Workflow
From technical 3D CAD modeling to cleanroom packaging, our structured workflow ensures repeatable dimensions and flawless finishes.
PHASE 01
CAD Modeling & Shrinkage Compensation
Our jewelry engineers analyze your design sketches or 3D files, calculating precise casting shrinkage allowances, stone setting seat diameters, and hinge pin clearances to ensure exact assembly.
PHASE 02
Master Prototyping & Mold Tooling
High-resolution SLA 3D wax printing is combined with vacuum investment casting or 5-axis CNC machining. First-article samples are evaluated for weight, comfort fit, hinge snap action, and polish fidelity.
PHASE 03
Multi-Axis Machining, Casting & Setting
Volume manufacturing utilizes vacuum induction casting and precision CNC turning. Experienced bench jewellers hand-set stones under stereoscopic microscopes, followed by robotic and artisanal hand-polishing.
PHASE 04
Class 10,000 PVD Coating & QC Audit
Pieces undergo multi-stage ultrasonic chemical cleaning before ionized PVD plating in Class 10,000 cleanrooms. Each batch passes 72-hour artificial sweat immersion, cross-hatch adhesion, and AQL 1.0 optical inspection.
Procurement Guidance
Frequently Asked Jewelry Inquiries
Common technical and commercial questions regarding custom jewelry production, PVD coating longevity, and sample development.
Why is 316L stainless steel superior to traditional brass or zinc jewelry?
316L stainless steel contains molybdenum, providing immense corrosion resistance against sweat, ocean water, and daily perfumes. It is completely hypoallergenic, will not oxidize green against the skin, and possesses superior hardness that resists dents and scratches.
How durable is your PVD and IP gold plating?
Our PVD (Physical Vapor Deposition) coating takes place in high-vacuum chambers where titanium nitride and real gold ions are molecularly bonded to the steel substrate. With layer thicknesses from 0.5 to 2.5 µm, our finishes pass 72-hour artificial sweat tests and maintain color integrity for years of regular wear.
What are your Minimum Order Quantities (MOQs) for custom jewelry designs?
Standard initial production runs start at 100 to 300 pieces per style, which can typically be distributed across multiple ring sizes or PVD plating colorways (such as 18K Gold, Steel, and Rose Gold).
Can you integrate custom branded logos and bespoke packaging?
Yes. We provide deep fiber laser engraving, embossed CNC marking, and hallmarking. Additionally, we produce complete retail-ready packaging suites including embossed microfiber pouches, rigid jewelry boxes, warranty cards, and barcode tags.
Can we sign a Non-Disclosure Agreement before submitting jewelry sketches?
Yes. We routinely execute bilateral NDAs with luxury brands, boutique designers, and retail groups. Your proprietary 3D CAD files, design sketches, and production molds remain strictly confidential.
