Metal stamping uses a press and custom-made dies to cut or shape stainless steel sheet. It is suitable for jewelry designs that require consistent shapes, clean outlines, and repeatable production.
For 316L stainless steel jewelry, stamping is commonly considered for flat pendants, nameplates, decorative tags, cutout designs, and selected formed components.

1. Design and Engineering Drawing
The technical drawing defines the shape, dimensions, holes, and decorative details. Designs involving bends or forming may also require a 3D drawing.
2. Stamping Die Making
A custom die is developed according to the approved design. Accurate tooling helps maintain consistent shapes and dimensions during repeat production.
3. Stamping
A press applies force through the die to cut or form the stainless steel sheet. Depending on the design, operations may include blanking, piercing, bending, forming, or embossing.
4. Additional Machining
Some designs require extra holes, precise features, or CNC machining after stamping. These are optional operations based on the product structure.
5. Deburring and Polishing
Burrs and sharp edges are removed, and the surface is polished to meet the required finish. Proper edge treatment is important for jewelry worn against the skin.
6. PVD Coating and Secondary Work
When required, the components receive a PVD finish after suitable surface preparation. Other finishing operations may include engraving, enamel application, or stone setting.
7. Quality Inspection and Packing
Finished pieces are checked for dimensions, edges, surface appearance, and assembly accuracy. Approved products are packed according to the order requirements.
Stamping is often used for flat pendants, nameplates, geometric shapes, cutout designs, and selected formed components. Deep, sculpted shapes may require investment casting or another manufacturing method.
Buyers should evaluate tooling costs, design feasibility, material thickness, edge quality, and expected order quantity. A custom die requires upfront investment, so the production volume and potential repeat orders matter when calculating unit cost.
Can 316L stainless steel jewelry be stamped?
Yes. Stamping can be used for suitable 316L stainless steel sheet components.
Does every stamped design require CNC machining?
No. CNC machining is added only when the design requires features that stamping cannot produce efficiently.
Can stamped jewelry have a gold finish?
Yes. PVD coating may be applied after the component has been properly finished and prepared.
