As a stylish and durable option, metal eyewear has long been a popular choice for those seeking fashionable and functional glasses. The production process of metal eyewear involves a series of intricate steps that transform raw materials into the sophisticated frames you see in stores. In this article, we will delve into the fascinating production process of metal eyewear, exploring each stage and shedding light on the craftsmanship behind these elegant frames.

Material Selection
The first step in the production process of metal eyewear is selecting the appropriate material. Metals such as stainless steel, titanium, and aluminum are popular choices for eyewear frames due to their lightweight, durable, and hypoallergenic properties. Each metal has its advantages and drawbacks, and manufacturers carefully consider factors such as cost, weight, and strength when making their decision.

Frame Design
Once the material has been chosen, the next step is designing the metal eyewear frame. Designers consider aspects such as style, comfort, and functionality when creating their designs. They must balance aesthetics with practical concerns, such as weight distribution and flexibility, to create a frame that is both visually appealing and comfortable to wear.

Cutting and Shaping
After the design has been finalized, the process of cutting and shaping the metal frames begins. Techniques such as laser cutting, stamping, and computer numerical control (CNC) machining are employed to create the various components of the metal eyewear. These processes involve the use of computer-aided design (CAD) software to create precise, intricate shapes and patterns that make up the frame.

Surface Treatment and Coloring
Once the frame components have been cut and shaped, they undergo surface treatment and coloring processes to achieve the desired appearance and finish. Surface treatment methods, such as electroplating, anodizing, or sandblasting, help to enhance the metal’s natural properties, provide a protective layer, and create a smooth, even surface. Coloring techniques like PVD (Physical Vapor Deposition) coating or painting add vibrant colors and unique patterns to the metal eyewear frames.

Assembly and Hinge Insertion
With the frame components treated and colored, the next step in the production process of metal eyewear is assembly. The various components, such as the front piece, temples, and nose pads, are connected using hinges, which are usually made of metal. The hinges are inserted into the frame components and secured using screws or other fastening methods. This step requires precision and attention to detail to ensure proper alignment and functionality of the eyewear.

Lens Fitting and Final Adjustments
The final stage in the production process of metal eyewear is fitting the lenses and making any necessary adjustments. The lenses are carefully inserted into the frame and secured in place. The eyewear is then checked for proper alignment and fit, with any final adjustments being made to ensure a comfortable and snug fit for the wearer.

In conclusion, the production process of metal eyewear is a complex and intricate journey that involves a series of carefully executed steps to create a stylish and durable final product. Each stage, from material selection to lens fitting, requires skill, precision, and attention to detail. By understanding the craftsmanship and dedication that goes into creating metal eyewear, you can better appreciate the quality, style, and comfort that these frames have to offer.

Next time you pick up a pair of metal eyewear, take a moment to consider the artistry and skill involved in their creation. The intricate production process behind these frames demonstrates the dedication and expertise of those who craft them, ensuring you receive a high-quality, fashionable, and functional product.

As a consumer, you might appreciate the stylish design and comfortable fit of acetate eyewear, but have you ever wondered about the meticulous process that goes into creating these fashionable frames? Acetate eyewear has been popular for decades due to its unique patterns, vibrant colors, and lightweight feel. In this article, we will delve into the fascinating production process of acetate eyewear and explore the steps taken to turn raw materials into your favorite pair of glasses.

Raw Material Extraction
The journey of acetate eyewear begins with the extraction of cellulose, a natural polymer found in plant cell walls. The primary sources for cellulose used in acetate production are wood pulp and cotton linters. These materials undergo a series of chemical treatments to isolate the cellulose from other components, such as lignin and hemicellulose.

Acetate Formation
Once the cellulose has been extracted, it is transformed into cellulose acetate through a process called acetylation. The cellulose is combined with acetic anhydride and an acidic catalyst, resulting in the formation of cellulose acetate. This material is then precipitated as flakes or powder using a solvent, typically acetone. Afterward, the acetate flakes are thoroughly washed and dried to remove any residual solvent.

Coloring and Plasticizing
The next step in creating acetate eyewear involves adding color and plasticizers to the dried acetate flakes. The colors and patterns of acetate frames are achieved by mixing pigments and other additives into the material. Plasticizers are essential to increase the flexibility and workability of the acetate, making it more moldable and easier to process.

Forming Acetate Sheets or Blocks
The colored and plasticized acetate mixture is then formed into sheets or blocks through a process called extrusion. During extrusion, the mixture is heated until it reaches a molten state and is then forced through a die to create a continuous sheet or block. These sheets or blocks are subsequently cooled and cut to the desired thickness.

Cutting and Shaping the Frames
Once the acetate sheets or blocks have been prepared, they are ready to be transformed into eyewear frames. This process involves cutting and shaping the acetate into the desired frame design using techniques such as computer numerical control (CNC) machining or laser cutting. The acetate sheets are carefully cut, milled, and sculpted to create the individual frame components, such as the front piece and temples.

Tumbling and Polishing
After the individual components of the acetate eyewear have been cut and shaped, they undergo a tumbling and polishing process to smooth their surfaces and remove any rough edges. This process usually involves placing the frame pieces in a tumbling machine filled with abrasive media and a polishing compound. As the machine rotates, the abrasive media gently polishes the acetate, giving it a smooth and shiny finish.

Assembly and Hinge Insertion
Once the acetate frame components have been polished, they are ready for assembly. The front piece and temples are connected using hinges, which are typically made of metal. The hinges are inserted into the frame components and secured using screws or heat-staked pins. This step requires precision and attention to detail to ensure a perfect fit and proper function of the eyewear.

Lens Fitting and Final Adjustments
The final stage in the production process of acetate eyewear is fitting the lenses and making any necessary adjustments. The lenses are carefully inserted into the frame and secured in place. The eyewear is then checked for proper alignment and fit, with any final adjustments being made to ensure a comfortable and snug fit for the wearer.

Observe whether the color of the frame is layered or floating on the surface:
the color of acetate eyewear is formed by layering after the cut process, and doesn’t fade acetate color; the injection eyewear is printed or dyed color or patterns on the surface, and will fade after wearing for a long time.

Observe whether there is a metal core insertion in the temples(leg): in order to improve and ensure the elasticity of the acetate eyewear for wear, the acetate eyewear usually inserts metal core in the acetate temples;

while in the injection eyewear, there is no metal core in temples, and the elasticity and firmness are slightly poor. But some manufacturers also use a slim metal core inserts in the temples(leg) of CP injection eyewear to improve elasticity and strength, but the slim core is definitely different from acetate metal wire core. It slim and don’t attached on hinges. The slim metal core only can be applied on CP injection eyewear, not all the injection eyewear.

Observe whether the nose pad is laminated:
the acetate eyewear nose pad is made by acetate chips and laminated on acetate eyewear front. Acetate eyewear nose pad can be same acetate front color or just use clear acetate.

while the injection frame, because it is an integral part of injection moulding, so included the nose pad as a whole. Through observation, we can find that the nose pad color or pattern is consistent or unified with the whole frame.

There are two types eyewear on the market: one is extruded with an plastic injection molding machine, which is called an injection molding eyewear. Another type of eyewear hand-cut with acetate sheets is called a acetate eyewear.

injection molding eyewear

injection molding eyewear first is produce a precision molds,then the liquid plastic is injected, then cooled and electroplated.

The injection molding eyewear has a low density, so it is easy to break. Because the plastic frame has simple production process and low production cost, it can be mass-produced, so the style changes a lot. Because it is electroplating and painting colors, there are many kinds of patterns, and the color is brighter and more colorful than acetate eyewear frame.

Please note that the injection molding eyewear generally has an injection point, which is a small scar on the edge of the frame, and the plastic frame is much lighter than acetate eyewear frame.

acetate eyewear

Because of acetate eyewear made of cellulose acetate material, it has the characteristics of toughness, transparency, good gloss, durability, discoloration caused by ultraviolet radiation, and no allergic to the skin. Therefore, acetate eyewear widely loved by consumers.

Among them, the characteristics of the acetate eyewear are high hardness, high strength, not easy to break, no deformation after wearing, no fading colors, acetate eyewear related of much more acetate materials used in the production, complicated handcraft process and high labor cost.

What’s the value of Handmade acetate eyewear in today’s commercial landscape? 
The quality and comfort of real handmade acetate eyewear product is so special.
With the market flooded with people selling acetate eyewear product on the cheap and pretending it is the same, the key is putting the handmade acetate eyewear on your face, the difference is obvious.

It seems amazing, that when a long time ago, acetate eyewear were perhaps the biggest chore, but today there is beautiful acetate eyewear product that looks great and feels great and makes people love their eyewear, if it isn’t handmade and comfortable, then the look becomes less cool.

As per a professional supplier for acetate eyewear, we only do one thing- handmade acetate eyewear.

As per a professional supplier for acetate eyewear, the perfect eyewear, is eyewear that is not only the most beautiful, but also the most comfortable. The lightness and elegance of acetate, makes this ideal a reality. In addition, acetate is truly a one of a perfect material, because the material is natural, creating something unique.
 

Each pair of acetate eyewear takes approximately 3 months to produce, handled by artisans in acetate eyewear factory. Most acetate eyewear designs take a year or more from concept to sales floor.

In current market of acetate eyewear, the acetate eyewear supplier and distributing enterprises are quite many; the acetate eyewear styles are diverse, quality levels vary. It’s always difficult for customers to choose. So, how to choose a good quality acetate eyewear? Hereby, we make a brief introduction as follows:

First, look at the surface. Try to choose the acetate eyewear for which the acetate and lenses surface is clear, shiny, of no scratches, bumps, corrosion and other problems.

Second, look at the marks. acetate eyewear from regular factories, except printing the number, size, dimensions, but also need printing the trademarks (Pinyin or English). And the printing is clear, unlike some no-name’s shoddy products.

Third, look at the structure. Pull the acetate eyewear two temples; put the acetate eyewear on the glasses or tables flatly. The acetate eyewear temples should be tilted 10 to 12 degrees angle; two rims shall be the same large, the temples shall be of the same length, the nose pads shall be of the same height, the temples shall touch on the same surface.

Fourth, look at the joint point; check whether the points between frames and temples fit or not. Acetate eyewear joint points of frames and temples should very flat and smooth.

Fifth, testing acetate eyewear material. When choosing acetate eyewear should select flexible and adjustable material. If the plastic eyewear material is non-flexiable, and not adjustable. it’s cheap injection molded plastic eyewear, not acetate eyewear. Top grade acetate eyewear are made of Zyle acetate, Mazzucchelli acetate.

Btw. when choosing metal eyewear, using hands to bend the rings or temples a little, and test the degree of hardness. Some are made of copper, stainless steel and iron. Top grade metal eyewear are made of nickel alloy which has high strength and flexibility, can be worn long time without distortion.

Regarding sunglasses and optical frame, although they are two different kinds of eyewear, but the identifying way are almost the same.

How to maintain acetate eyewear or glasses?

Following are some tips for teaching you how to maintain acetate eyewear.
1, acetate eyewear and optical frames’ wearing: Hold the temples with both hands and along with parallel lines around cheeks, if use single hand, the frames will be deformed, balance will be destroyed.

2, folding the acetate eyewear should be started from the left temples. Most of the acetate eyewear are designed to be folded from the left temples. If folding the right temples first, the acetate eyewear will be easily deformed.

3, the rotation method: if it is a temporary placing of acetate eyewear, the lenses’ convex should be put upward. If put convex downward, the lenses will be scratched.

4, method of cleaning lenses: use a special lens-cleaning cloth; hold the side of the acetate eyewear edge wire, wipe the lenses gently. Avoid excessive force resulting in acetate eyewear or lens damage.

5, when lenses are dusty or dirty, dry-rubbing will scratch the lenses easily. It is recommended rinse the lenses firstly, then using tissue to sop up the water, lastly wipe up the lenses with a spectacle cloth. If the lenses are really dirty, it is recommended to use low concentrations of mild detergent, then rinse and dry.

6, please wrap the acetate eyewear well with cloth and use the spectacles cases if not wearing acetate eyewear. When saving, please avoid touching with insect repellent, toilet articles, cosmetics, hair spray, drugs etc. these corrosive materials, otherwise it will cause the lenses and frames’ degradation, deterioration, discoloration.

7, the deformation of acetate eyewear. This will bring burden for ears and noses, also the lenses are easy to loose. It is recommended a regular adjustment will be made in a professional spectacles store.

8, do not use in intense exercise. For resin lenses, if under strong impact may possibly be broken; this will also easily lead eyes and facial injuries. So acetate eyewear and optical frames are not recommended to be used during intense exercise.

9, do not use scratched lenses. Better not use lenses which have scratches, blemishes, cracks, etc.; otherwise they will loose the color of light, so we cannot see things clearly, and then decreased vision will be caused.
10, do not look steadily at sun. Even if the lenses have color difference, and do not look directly at the sun or strong light, otherwise it will hurt the eyes.

11, only after getting used to wear acetate eyewear then start the driving and other operations. Due to prism lenses, wearing new purchasing acetate eyewear, it is difficult to grasp the sense of distance. If not fully getting used to them, do not drive or operate.

 12, no long-term placement at a high temperature (60C or above). High temperature will easily lead to lens distortion or heat the surface of the film cracks easily; please do not put the acetate eyewear in front windows of the cars, expose with direct sunlight or high temperatures.

　13, if the lenses are wet, please wipe it dry immediately. If waiting for natural dry, water scale will become difficult to be wiped clean and stain to see things clear.

14, clean sweat, cosmetics marks and dry. When the lenses are attached with sweat, juice, hairspray (plastic), cosmetics, etc., immediately rinse and dry. If not in time will cause film off.
