Production

We collaborate with leading eyewear manufacturers in China and Italy, partnering with some of the most respected names in the industry to produce eyewear of exceptional quality.

Each pair of glasses undergoes over a hundred intricate production steps, executed by skilled artisans across specialized production lines. Working closely with technicians, these craftsmen follow precise protocols to ensure that every component is carefully crafted into a distinctive part of the final product.

Our partner factories are equipped with advanced technical infrastructure, including high-precision automatic and semi-automatic machinery for milling frame fronts, lenses, and various components.

To maintain the highest quality standards throughout the production process, each step is subject to rigorous quality control. Before completion, every pair of glasses goes through a critical adjustment phase. All elements—whether optical frames or sunglasses—are meticulously inspected, with particular attention to fit, one of the most essential aspects of performance and comfort.

Finally, each pair is packaged in the brand’s custom-designed packaging, which not only protects the eyewear during transport but also serves as a vital expression of the brand’s identity and image.

The process of eyewear production (for both prescription glasses and sunglasses) involves several key stages that blend craftsmanship, engineering, and automation.

The eyewear production process varies based on the type of frame material, including acetate, metal, plastic (such as TR90 and Ultem), carbon fiber, and titanium.

1. Acetate Eyewear Production

Material: Cellulose acetate (plant-based plastic)

Process:

Sheet Cutting: Large acetate sheets are cut into frame fronts and temples using a CNC machine.

Milling: Detailed grooves (for lenses and hinges) are milled.

Lamination (if needed): Layers are pressed together for color combinations or patterns.

Tumbling: Frames go into vibrating drums with abrasive materials for polishing (can take days).

Hand Polishing: Final buffing for high-gloss finish.

Assembly: Temples and hinges are attached, usually with rivets or heat.

Adjustment & QA: Frame shape is heat-adjusted for proper fit and then inspected.

2. Metal Eyewear Production

Material: Stainless steel, Monel, aluminum, etc.

Process:

Stamping or Laser Cutting: Sheet metal is shaped into frame fronts.

Bending/Forming: Machines or artisans bend bridge and end-pieces.

Soldering: Parts like bridges, nose pad arms, and hinges are soldered together.

Polishing: Mechanically or manually polished for smoothness.

Plating: Metal is electroplated with nickel, gold, silver, etc.

Assembly: Nose pads, hinges, and temples attached.

QA & Finishing: Alignment and coating inspection.

3. Plastic Eyewear Production (TR90, Ultem)

Material: Thermoplastic (TR90), high-performance resin (Ultem)

Process:

Injection Molding:

Pellets of TR90 or Ultem are melted and injected into molds.

Very efficient for mass production.

Cooling & Ejection: Molded parts are cooled and removed from the mold.

Trimming: Excess plastic or flash is trimmed off.

Surface Finishing: Light polishing, painting, or texturing.

Assembly: Hinges (usually with screws or flex hinges) and temples attached.

QA & Testing: Tested for flexibility, heat resistance, and color consistency.

Note: TR90 is flexible and lightweight, used in sports or budget frames. Ultem is more durable and heat-resistant, popular in high-end flexible eyewear.

4. Carbon Fiber Eyewear Production

Material: Carbon fiber-reinforced polymer

Process:

Pre-preg Layer Cutting: Pre-impregnated carbon fiber sheets are cut to shape.

Molding: Layers are stacked in a mold, then compressed and cured in high heat and pressure (autoclave or compression mold).

Trimming & CNC Milling: Edges are cleaned up and milled to precision.

Surface Coating: Clear or matte coatings for UV protection and aesthetics.

Assembly: Usually bonded with titanium or stainless steel temples due to carbon’s stiffness.

Final Inspection: Checked for defects like delamination or air bubbles.

Note: Carbon fiber frames are ultra-light, strong, but expensive to produce.

5. Titanium Eyewear Production

Material: Pure titanium or beta titanium alloy

Process:

Cutting: Titanium sheets or rods are laser-cut or stamped.

CNC Machining: For detailed shaping and precise fit.

Bending & Forming: Using high-force machinery or heating.

Welding: Parts are joined with laser or micro welding.

Polishing: Multiple polishing steps for a smooth surface.

Anodizing/Coating: For color, corrosion resistance, and finish.

Assembly: Hinges, screws, and temple tips added.

QA & Testing: Stress-tested for flexibility, corrosion resistance, and weight.

Note: Titanium is hypoallergenic, corrosion-resistant, and ultra-light—ideal for premium or medical-grade eyewear.

General Final Steps (All Materials)

Lens Insertion: Prescription or sunglass lenses are edged and mounted.

Adjustment: Frames are shaped for comfort and symmetry.

Branding: Logos, model numbers, or engravings are added.

Packaging: Cases, cloths, and marketing inserts included.
