Private label production process / proceso de fabricación

Xylvester can help you to transform your idea into eyewear collections. We have 4 productions lines and we can manufacture glasses from acetate, eco acetate, recycled acetate, bio based acetate, stainless steel, monel and silver nickel.

 

The use of environmentally sustainable materials and process (eco/recycled/bio acetate), aims at a constant reduction in environmental footprint. Regarding to the production capacity, annually we can produce more than 2.000.000 pairs of glasses.


The minimum order quantiy for acetate glasses is 300 units per design. Each design may be done in 3 colors, 100 units per each color.


The minimum order quantiy for metal glasses is 600 units per design. Each design may be done in 3 colors, 200 units per each color.

 

In case you are not sure about the glasses shape, we can first build a prototype sample for you before ordering the mass production.

The sunglasses or eyeglasses production ( gafas / lentes ) consists of more than 40 steps. Here we would like to introduce you the most important ones.

1. Design:

The creative process initiates here, with some individuals sketching by hand, while others utilize design software or CAD. Our design team can help customers to create their designs from scratch fully customizable, resulting in eyeglasses technical drawings.

2. Machining Front and Temple:

When the acetate sheets are received, they are cutted. Fronts and temples undergo shaping, predominantly carried out by CNC machines, all this process is fulfilled according to the technical drawing.


3. Wirecore Insertion:

Regarded as one of the most challenging steps, core insertion traditionally involves laminating acetate around a wire, a time-consuming process. However, our proprietary method allows for the lamination of three-dimensional wires, although this is rarely done now. For the majority of frames, a temple core is heated to high temperatures (>300C), the acetate is heated with special HF heaters, and the core is pressed into the acetate using a mold/jig and a piston.


4. Barrel Polishing:

After initial hand-finishing using files and scrapers, parts are placed in polishing barrels or tumblers. These barrels contain media made of plastic, wood chips, or bamboo chips of varying sizes and shapes, along with polishing compound and/or oil. The parts tumble for 4-5 days.


5. Hinge Attachment:

Front hinges are attached after polishing, either before or after being capped. Hinges are heat sunk or riveted, with pins pushed through holes in the frame and hinge, and then "headed."


6. Hand Polish:

Achieving excellent finishes demands careful attention to detail, making this the most time-consuming step. Polishing can occur at various points in the process. Wheels of various materials and construction, along with different compounds or "grits," are utilized. This artful process significantly impacts how the frame retains its shine over time.


7. Print, Temple Bend:

After polishing, temples undergo printing using methods such as pad and laser printing. Temple tips are heated and bent, either by hand or in a special machine.

8. Lens Insertion, Final Adjustment:

Frames are heated, adjusted, and lenses are cut and fitted. The final inspection ensures quality, and the frames are packaged and ready for distribution.
