What we place, and what we check it against
Materials run across the Wenzhou and Shenzhen clusters; the judgment of where each build belongs — and the inspection it must pass — is ours. This page is the standing reference: every material, branding process and test line, with the failure mode we watch for. If your spec names something that isn't here, ask — the answer is a judgment, not a menu.
Every material, placed on the floor that builds it well
| MATERIAL | WHAT WE RUN | WHAT WE CHECK |
|---|---|---|
| ACETATE — SHEET | Milled and hand-finished; laminated (spliced-color) builds included. | Spliced-color work lives or dies on bleed control — clean edges at the splice are an incoming-inspection item, not a promise on a quote. |
| THIN ACETATE — 2–3 MM | Ultra-thin builds on slower, dedicated lines. | A 2–3 mm sheet needs a two-step bend to shape without stress — which is exactly why these builds get placed, not improvised. |
| METAL & TITANIUM | Wire and sheet builds, β-titanium included; plating and color coats run on specialist lines. | Color coats that hold on metal are one of our standing engineering references — the write-up lives in the golden cases. |
| INJECTION — TR-90 & PC | Sport and volume builds. | Checked against the same boxed-lens tolerance as every other build: ±0.5 mm. |
| MEMORY ALLOY | Memory bridges and temples. | Checked to return true at −10 °C — cold-weather markets find a weak batch before your customers do. |
| COMBO — METAL + ACETATE | Two materials in one frame. | Combos fail at the joints when alignment drifts — alignment is gauged first on the sample and last before packing. |

Your logo, and what we check it against
Nine ways to put your name on a frame — each with its own failure mode. Which one survives your market's handling depends on the frame material and the retail price point; that call is part of the engineering review, not an upsell.
| PROCESS | WHAT IT IS | WHAT WE CHECK |
|---|---|---|
| Pad print | Ink transfer, flat or curved faces | Cross-cut adhesion after cure |
| Silk print | Screened ink, lens or acetate | Edge sharpness, no ghosting |
| Laser engrave | Marked into metal or acetate | Depth consistency across the run |
| Laser + paint | Engraved, then paint-filled | Fill level — no overflow, no voids |
| UP sticker | Raised metallic transfer | Edge lift after tape pull |
| Inlay | Metal badge set into acetate | Flushness — a nail shouldn't catch |
| Metal etching | Pattern etched into temple stock | Salt-spray corrosion resistance |
| Metal trim | Applied metal emblem | Seat tightness after cycle test |
| Stone setting | Rhinestones in engraved seats | Widest section 0.1–0.2 mm below the surface; 3M tape pull per batch |
The batch answers to the same tests, every time
"Defective" is a measurement, not an argument. Sampling runs per ISO 2859-1; defect classes — critical, major, minor — are agreed in writing before production starts.
| TEST | PASS LINE |
|---|---|
| Artificial perspiration | > 24 h, no corrosion |
| Nickel release | < 0.5 µg/cm²/week |
| Boxed-lens dimensional tolerance | ± 0.5 mm |
| UV resistance (color shift) | < grey-scale grade 3 |
| Frame durability (deflection) | < 5 mm |
| Cross-cut adhesion (coatings, prints) | pass required |
Market compliance handled as part of the job: CE (EN ISO 12870 / ISO 12312-1), FDA 21 CFR 801.410, ANSI Z80.3, AS/NZS 1067, REACH, California Prop 65. What fails our inspection does not ship — we have held batches and eaten the delay.
