What manufacturing processes are used for tennis jewellery?

The process commonly begins with a design brief, technical drawings, and CAD files that define link dimensions, stone seats, clasp geometry, and tolerances. A master model or production mold follows when the design is suitable for casting; stamped or machined components may use dies or CNC preparation instead. Metal components are then formed, trimmed, assembled, and progressively polished. Stones are set after the seats and surfaces are prepared, followed by plating or another specified finish where required. Final checks review dimensions, articulation, clasp operation, stone security, surface appearance, and order-specific acceptance criteria. Approving a preproduction sample is important because a screen-rendered CAD model does not show polishing loss, assembly clearance, or final color accurately.

Setting design controls both security and labor. Prong settings expose more of each stone but require accurate seat cutting and careful finishing around small claws. Bezel or channel-style construction can provide different protection and visual coverage, but it changes metal usage, link geometry, and setting time. Stone matching also affects cost: variation in diameter, depth, or shape can create uneven spacing and require additional sorting or adjustment. Buyers should specify stone size tolerance, acceptable visual variation, setting type, and a method for checking looseness. A sample should undergo handling and articulation review before bulk approval, since a rigid display sample may not reveal movement-related stress at the links or clasp.

The suitable combination depends on the required appearance, wear expectations, market positioning, and compliance scope. 925 silver provides a precious-metal base, brass is commonly used for cost-sensitive fashion construction, and gold vermeil combines a silver base with a gold surface layer under the applicable product definition. The specification should identify base metal, gold color, plating or coating requirements, polished or textured areas, and any restricted-substance or market testing expectations. Finish selection cannot be judged by color alone: surface preparation, edge rounding, handling, and storage influence the result. Request a physical sample and written finish standard so bulk goods can be compared against an approved reference rather than an image.

Casting is useful when links contain relief, curved profiles, integrated details, or geometry that is difficult to form from sheet. Lost-wax investment casting can reproduce those shapes, but it introduces gates, sprues, shrinkage considerations, and more finishing work. Stamping is often suitable for flatter, repeatable components made from sheet, particularly when consistent thickness and efficient repetition matter. Some collections use a hybrid route: stamped structural parts combined with cast connectors, settings, or decorative elements. The decision should follow the CAD geometry, minimum wall thickness, desired weight, production volume, and tooling budget. A manufacturer should review a technical drawing and sample rather than recommend a process from the product name alone.

Color consistency begins with a stable base surface. Polishing, cleaning, and masking determine how evenly the finish accepts the plating or coating. The buyer should specify the target color, surface areas, layer or thickness requirement where applicable, and the approved visual reference. Production controls may include bath management, process records, sample comparison, and measurement by an agreed method; the exact testing approach depends on the finish and destination market. Appearance is not proof of thickness, and two pieces with similar color can have different wear performance. Approval should cover edges, recesses, clasp components, and assembled areas because current distribution can vary across complex articulated jewellery.

A practical inspection plan covers several checkpoints rather than relying only on a final visual review. Incoming checks can verify stones, metal components, findings, and color references. During production, reviewers should examine mold or die output, link dimensions, seat alignment, polishing marks, plating coverage, and assembly clearance. Final inspection should test clasp engagement, articulation, stone movement, sharp edges, surface defects, packaging, and quantity. The sampling level and defect definitions should be agreed in the purchase specification; AQL is a sampling framework, not a universal quality level. Depending on the target market, buyers may also request documentation or testing related to restricted substances, plating performance, or jewelry safety. Records should link results to the approved sample and batch.
