Custom Swimming Goggle Design — OEM/ODM Process

Last updated: 31 May 2026

Taipei Design Center

Design and product engineering run from our Taipei Design Center; tooling, testing, and manufacturing happen in our Suzhou facility — one connected workflow from first sketch to packed pallet. Start from an existing platform (OEM) or commission an original design (ODM); the stages and controls are the same.

Every project starts under mutual NDA. We segregate IP between brand programs, and prototypes are destroyed on completion. Each of the five stages closes with a formal sign-off and gate review before the next one opens — changes get caught when they're cheap, not after tooling is cut.

The same model runs across private-label fitness swim goggles, performance racing lines, corrective-lens optics, and junior ranges. Browse the catalog to see what's already in production.

Concept & Design

Typical timeline: 4–8 weeks
Client involvement: Brief approval and concept sign-off

Every project starts with the brief. We agree the product's purpose, target swimmer, fit philosophy, and visual language alongside the commercial frame — positioning, price tier, where it'll get used (50 m pool, open water, kids' learn-to-swim, daily fitness). Our industrial designers work from the Taipei Design Center, running form-factor and styling studies across the categories we know — wide-vision, racing, corrective-lens, junior, training. The look and the function get decided together: hydrodynamics, comfort, and seal stability shape the lines from the first sketch.

Digital Design & Engineering

Typical timeline: 3–6 weeks
Client involvement: 3D-rendering review and Go / No-Go approval on the digital mock-up

Approved concepts move into CAD. Design and engineering happen in the same room and the same model file, not in two siloed hand-offs — the payoff of a vertically integrated supplier. We model lens geometry, gasket structures, nose bridges, strap systems, and every interface between them. Ergonomics, pressure distribution, sealing behavior, and manufacturability all get tuned here, against the actual production constraints — gating, draft angles, cycle time, tolerance stack. Catching a problem in CAD costs nothing; catching it after the mold steel is cut costs five figures.

Prototyping & Validation

Typical timeline: 4–8 weeks
Client involvement: Hands-on prototype review with swim testing

Physical swim goggle prototype on a fit-testing rig at the Eyeline pilot line — Design stage prototype for swim testing

Physical prototypes are produced so digital designs can be validated in real-world conditions. Swimmers test them in water — fit, comfort, seal stability, how the lens reads in a turn. Then we iterate. Material durometer, flex, anti-fog coating life, and lens clarity get adjusted against the test results. The design has to meet its functional brief before any tooling steel is touched.

Tooling & Production Preparation

Typical timeline: 6–9 weeks

Precision injection-mold tooling for swim goggle production at the Suzhou facility — Mold pre-fabrication design review

Validated designs move into tooling. We build the molds, jigs, and assembly fixtures in our Suzhou tool room and qualify them on the same floor that runs production — same engineers, same machines, no warehouse transit between the two. Gating, shrinkage, surface finish, and assembly tolerances get resolved before the first production batch, not after. We then define and run process windows — injection pressure, melt temperature, cooling time — until output is repeatable shot to shot. By the time a design leaves this stage, it's a manufacturable product, not a hopeful one.

Your tooling. Your IP. Documented in writing.

Ownership terms get agreed at project start — customer-owned or Eyeline-owned, both models work. See the FAQ for the specifics.

Scaled Manufacturing

Typical timeline: 6–12 weeks (volume-dependent)
Client involvement: First-shipment approval and ongoing program review

Toyo SM130-7 injection molding machine at the Eyeline Suzhou factory — producing swim goggle frames and lens components — Injection Molding

Approved products move into mass production. Every key process — injection, coating, assembly, inspection — runs inside our own walls, which is what lets us hold quality tight from a 5,000-pair launch order all the way up to six-figure annual programs. Component molding, sub-assembly, final assembly, inspection — every step has a documented control plan and an operator signed against it. Output stays stable shot to shot, batch to batch, year to year. That's what OEM and ODM partners actually need; "consistency" is the brochure word for it.

Frequently Asked Questions

How long does it take to develop a custom swim goggle from scratch?

A full ODM project typically runs 6–13 months from approved brief to first scaled production batch, across our five design stages. Programs with genuinely novel features — new lens geometry, new gasket compound, new optical tech — extend to 13–24 months because we add test-and-iterate cycles before committing tooling. Programs built on an existing OEM platform are much faster: same fit and lens, new color and branding, first samples in 2–4 weeks and first carton in 60–90 days.

Who owns the tooling once a custom swim goggle project is complete?

Tooling is physically held at our Suzhou factory; ownership terms are settled in the OEM/ODM contract before we cut steel. Both customer-owned molds (customer pays the tooling cost in full, mold is theirs) and Eyeline-owned molds (no separate tooling fee, mold stays with us and is run only for that customer's program if exclusivity is contracted) are common. See the main FAQ for the three standard ownership structures.

What's the minimum order quantity (MOQ) for a custom swim goggle design?

Standard MOQ is 2,000 pairs per color per model at baseline pricing. Smaller runs are available on a published surcharge schedule (×1.04 at 1,200 pcs, ×1.09 at 600 pcs, ×1.15 at 300 pcs). Programs that build on an existing OEM platform can start from 300 pairs per color. Programs requiring a new mold need enough projected volume to amortize the tooling cost — typically 15,000–60,000 pairs for OEM and 30,000–80,000 pairs for ODM, depending on tooling complexity. New Pantone colors carry their own 15,000-pair minimum per dye lot. Each quote is sized against your actual annual program, not a static catalog price.

Do you sign NDAs at the start of a design project?

Yes. Every ODM and private-label engagement starts with a mutual NDA before any design work begins. Brand concepts, CAD files, and prototype iterations sit on isolated project workspaces with restricted access — even within the factory, only the named project team can see them. On project completion, prototype tools and unconverted samples are destroyed under documented IP-segregation procedures.

Can clients visit the factory for prototype review?

Yes — some brands send a small team for in-person reviews at our Suzhou factory at two points: once at the digital engineering stage to walk the CAD on a screen with our team, and once for physical prototype validation when there's something to hold and try on. Remote-only review is also fully supported (3D CAD walkthroughs over video plus shipped sample sets), which is how most brand reviews ran during the 2020–2022 period and still works well. Each stage closes with a formal sign-off before the next stage starts.
