Manufacturing Protocol
Precision Production Workflow
From technical CAD validation to cleanroom quality inspection, our engineering workflow ensures strict repeatability.
PHASE 01
Engineering DFM & Blueprints
Our engineers inspect your 3D CAD files or reference samples to calculate shrinkage compensations, wall thicknesses, and tooling paths. Comprehensive 2D manufacturing blueprints are delivered for sign-off.
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 undergo dimensional verification, tactile fitment, and finish audits.
PHASE 03
Multi-Axis Machining, Casting & Polishing
Batch manufacturing utilizes multi-spindle Japanese CNC equipment, robotic surface buffing, and master hand-applied satin graining. Pieces undergo strict optical inspection before plating.
PHASE 04
Class 10,000 PVD Plating & Cleanroom QC
All ionized PVD deposition and final packaging takes place in ISO Class 10,000 cleanrooms to eliminate airborne dust. Every completed piece passes 72-hour artificial sweat immersion and AQL 1.0 optical checks.

Frequently Asked Questions
Common technical and commercial questions regarding custom bangle manufacturing, MOQ, sampling, and private label supply.
Why are oval bangles superior to round bangles?
The human wrist is naturally oval in cross-section. Oval bangles prevent the piece from spinning unnecessarily on the wrist, keeping decorative elements and gemstones facing upright.
How does the hidden hinge mechanism operate?
The hinge is completely internal, utilizing a high-precision micro-pin inserted within CNC milled intermeshing knuckles. From the exterior, only a hairline seam is visible.
Can open torque cuffs be bent by the wearer without cracking?
Yes. Our open cuffs are heat-treated and annealed to achieve optimal spring temper, allowing slight manual flexing for wrist fitment without metallurgical fatigue or distortion.
What is the MOQ for custom bangles?
Standard MOQ starts at 200 pieces per style, which can be split across sizes and finishes. For hinged or stone-set constructions the MOQ depends on tooling complexity, so we confirm the exact figure with your quotation before development begins.
How much do samples cost and how long do they take?
Samples are typically ready in 15 to 20 working days after drawing sign-off. Sample fees depend on construction and finishing, and where a bulk order follows, sample fees can be credited against production under written agreement.
Will the PVD gold finish fade or tarnish in daily wear?
Our high-vacuum 18K PVD coatings are deposited at 1.5 to 2.0 microns and verified with 72-hour artificial sweat immersion testing. In normal daily wear they substantially outlast conventional electroplating, though we advise against abrasive polishing.
Can you produce bangles under our own brand?
Yes. We support laser and rotary engraving of your logo, plus custom presentation boxes, microfiber pouches, and branded polishing cloths, with packaging engineering confirmed at the sample stage.
What packaging options do you provide for luxury bangles?
We provide custom-sized rigid presentation boxes with debossed leatherette interiors, soft microfiber travel pouches, and branded polishing cloths.
