Custom tennis mounting prototypes developed by BOSA

Custom Development

From a sketch, a reference photo or a full CAD file — we develop exclusive tennis mountings for your brand, backed by 20+ years of mould development and product engineering.

Your design. Our engineering.

You bring the idea and the constraints. We resolve them into a mounting that can be produced at volume, run after run.

CAD and mould engineering workstation for custom tennis mountings

Built around your constraints

Stone size, karat, target weight, setting method — every custom mounting is engineered around the numbers that matter to your production, not around what is easiest to cast.

Custom designs stay yours

Mountings developed for your brand are produced exclusively for you. Your designs, moulds and technical files are protected under confidentiality.

Finished tennis bracelets produced for a brand line
Exclusivity

Developed for one brand. Yours.

An exclusive mould is not a service we add on — it is how a custom line stays yours, season after season.

Process

From idea to production in four steps

CAD-defined link geometry of a tennis mounting

Step 01 — Design & CAD

We translate your idea into a production-ready CAD model, optimized for stone size, weight target and setting method.

Precision mould engineering for a custom tennis mounting

Step 02 — Mould engineering

Precision moulds are developed in-house — the foundation of consistent, repeatable production.

Physical sample mounting prepared for approval

Step 03 — Sampling

You receive physical samples for approval. We refine until fit, drape and finish are exactly right.

Full-scale production of a custom tennis mounting line

Step 04 — Production

Full-scale manufacturing with consistent quality control — exclusive to your brand.
