Private label & OEM/ODM sports sunglasses for cycling, running and outdoor brands. TR90 frames, photochromic and polarized lenses, 30+ design patents. MOQ 300 pcs per color, 7-day samples, 20-25 day production.
Every Julong line is engineered for a specific sport and built for OEM/ODM customization: your logo, your Pantone colors, your retail packaging. MOQ from 300 pcs per model per color, with 5-15 new shapes added to the catalog every year.
Lightweight TR90 frames with polarized and contrast-enhancing lenses, non-slip silicone fit.
Photochromic & polarized lenses auto-adjust to light; flexible TR90 with anti-scratch coatings.
TAC polarized lenses eliminate water glare; hydrophobic coating sheds spray and sweat.
Built-in buoyancy frame keeps sunglasses on the surface – never lose them on the water.
PC shatter-resistant lenses with high-contrast technology; non-slip silicone for sudden moves.
TAC polarized + PC high-contrast lenses for tracking fast balls; lightweight TR90 frames.
Since 2011, our 105-person team has molded, assembled and inspected every frame in-house: two bases, an 8,000 m² dust-free workshop, 90% OEM/ODM output, zero outsourcing.
A startup founder, a distributor and an e-commerce power seller have three different fears. Our OEM/ODM system answers each one with the same engineering discipline, and the same 300-piece entry point.
“We worry the factory cannot execute our complex 3D design – or that the design leaks to competitors before launch.”
“A supplier running out of capacity mid-season – or failing customs on paperwork – costs us retail accounts.”
“Public-mold listings get flagged for infringement, and we need fresh SKUs plus listing-ready images fast.”
Frame material decides weight, comfort, durability, and unit cost. Here is how the four materials we process daily actually compare.
| Property | TR90 (Grilamid) | Polycarbonate (PC) | Nylon (PA12) | Carbon Fiber |
|---|---|---|---|---|
| Frame Weight | 18-22 g – lightest flexible option | 22-28 g | 20-24 g | 15-19 g – lightest rigid option |
| Flexibility | Excellent – bends under load and springs back | Medium – stiff, limited flex | Very good – semi-flexible | Low – fully rigid by design |
| Impact Resistance | Excellent – absorbs drops and twists | Excellent – highest raw impact strength | Very good | Good – vulnerable to sharp point impacts |
| Heat Resistance | High (softens ≈160°C) | Medium (≈130°C) | High (≈145°C) | Very high – stable beyond 200°C |
| Unit Cost | Medium-high | Low – most economical | High | Very high (3-5× TR90) |
| Best For | Cycling, running, all performance OEM lines | Entry-level, ball sports, promotional programs | Premium optical-grade builds | Flagship racing and limited editions |
Typical values for finished sport sunglasses frames; exact figures vary with wall thickness, lens size and hardware. Request a material datasheet with your quotation.
TR90 is the performance default – the lightest flexible frame at a mid-range price, which is why it anchors our cycling and running catalog. PC wins on budget and raw impact strength, nylon suits premium optical builds, and carbon fiber is reserved for flagship racing. Unsure? Send your target price and sport – our engineers return a material recommendation within 24-48 hours.
Ask Our EngineersA frame holds the lens; the lens sells the product. Four coating and material technologies cover every light condition your end users face, all applied, assembled and verified in-house.
VLT auto-adjusts from light to dark within seconds as UV intensity changes – one lens covers dawn starts, midday sun and cloudy returns. Riders stop swapping lenses mid-ride, and your SKU count stays lean.
Cycling · Running, All-Day Outdoor
A polarized filter layer blocks up to 99% of horizontal glare from water, wet asphalt and car hoods. The result: sharper contrast, truer depth perception and far less eye fatigue on long sessions.
Fishing · Waterside, Bright Flat Light
Every lens blocks 100% of UVA and UVB up to 400 nm, verified on our in-house UV spectrometer – not just claimed on a spec sheet. UV380 alternatives leave part of the UVA band unfiltered.
Every Market · Compliance Baseline
Twelve REVO mirror colors – blue, gold, red, green, silver and more – matched to your frame palette for maximum shelf and listing impact. Multi-layer vacuum coating resists peeling and salt spray.
Premium Lines · E-Commerce Hero Images| Technology | VLT Range | Glare Handling | Best Use |
|---|---|---|---|
| Photochromic | Auto-adjusts ≈15-85% within seconds | Medium | Variable light, all-day wear |
| Polarized (TAC) | Fixed ≈10-40% | Blocks up to 99% horizontal glare | Water, wet roads, flat bright light |
| UV400 Base Lens | Depends on tint | UV absorption, not glare | Compliance baseline on every lens |
| REVO Mirror | ≈8-30% | High surface reflection | Strong sun + premium visual identity |
VLT = Visible Light Transmission. All lens options are available on PC, TAC or nylon substrates and can be combined – for example, photochromic + polarized + REVO mirror on a single cycling lens.
Every project gets a dedicated R&D engineer, a physical prototype for approval, and 100% final inspection. Here is the exact path your sunglasses take.
Share sketches, reference images or 3D files. Our 8 R&D engineers return structural suggestions, a Design-for-Manufacturing report and cost targets – before any tooling money is spent.
24-48 hrsPhysical sample via 3D printing or CNC. You test fit, weight, lens angle and comfort on real faces before committing to steel molds.
7 daysPre-Production Sample in your exact TR90 material, Pantone colors and logo. You sign off the PPS before mass production begins – no surprises on the line.
12-15 daysDust-free assembly, automated lens cutting, inline QC at every station. 80,000-100,000 pcs monthly capacity keeps first orders and repeats on schedule.
20-25 daysEvery single piece – not a sampling batch – passes drop-ball, UV verification and hinge cycle checks before it is allowed into packing.
100% inspectedRetail color boxes, hard cases or bulk packing to your spec. We book freight under FOB, CIF or DDP terms – to your warehouse, your distributor or FBA.
