Comprehensive Knowledge of Glasses Manufacturing and Glasses [Part 2]

The material and quality of the glasses frame

In general, the materials of glasses frames are divided into two categories: metal and plastic.

Metals are divided into: titanium and ordinary metal materials. Titanium is divided into alloy titanium, pure titanium, ultra-thin and ultra-light B titanium. Metals are divided into stainless steel, white copper, copper and other materials. A pair of metal frames is often made of several different metal materials according to different structures. For example, in order to make the glasses have a certain elasticity, the bridge and temples of the glasses are mostly made of stainless steel;

 

Plastics are divided into: heavy acetate, thin TR materials, recently started ULTEAM materials, and other plastic products. Glasses made of acetate are the most popular type of glasses in recent years. acetate glasses have the advantages of rich colors, complex structures, and high matching with clothing, so they are loved by many people. The following is a pair of plate sunglasses.

In terms of materials and popularity, titanium glasses are the highest grade, followed by acetate glasses, metal glasses, plastic glasses, etc. Of course, some glasses made of natural materials, such as buffalo horn glasses and wooden glasses, are often called luxury goods among glasses because of their expensive materials and complex processes.

 

Titanium glasses. Titanium glasses have many advantages. First, they are lightweight, which is important for people who wear them for a long time, especially those who need to wear them all day. Then, titanium is corrosion-resistant and not easy to rust, which is suitable for people who sweat easily or live in humid environments. There is also anti-allergy, because some people may be allergic to metals, and titanium is generally safer. In addition, titanium has high strength, and the glasses frame will be more durable and not easy to deform, which may be helpful for those who are active or accidentally press the glasses. In terms of design, titanium is more flexible and can be made into more fashionable styles to satisfy users who pay attention to appearance. It may also be mentioned that titanium glasses have low maintenance costs, because they are durable and may be more cost-effective in the long run. Therefore, although the price of titanium glasses is relatively expensive due to the high cost of titanium materials and the complex process of titanium glasses, it is still cost-effective to buy titanium glasses from the above advantages of titanium glasses. Therefore, titanium glasses are also one of the most popular types of glasses.

 

However, different titanium frames are also very different, which can be summarized as follows:

1. The most expensive and best B titanium glasses at present have advantages such as ultra-thin, ultra-light, and good elasticity, but they are difficult to process and form, and require better equipment and a higher defective rate, so the cost is relatively the highest.

2. Pure titanium glasses frames usually appear in the form of thick frames and titanium columns. Pure titanium is relatively soft and easier to shape, which is more suitable for making titanium glasses frames with patterns. Pure titanium is much lighter than other metals.

3. The cheapest is alloy titanium. It is an alloy of titanium and other metals. Only the lower-end titanium glasses frames are made of titanium alloy.

Of course, a good pair of titanium glasses frames is not necessarily made of one material. Different materials will be selected according to the needs of design and structure. For example, the pattern of the wire and the temples will be made of pure titanium, which has a clearer and cleaner texture. When elasticity and strength are required, beta titanium materials are often used, and the most common parts are the bridge and temples of the glasses.

Acetate glasses and acetate sunglasses.

 Acetate glasses can be said to be the most popular type of glasses at present. Almost every luxury eyewear brand has an acetate glasses series. What are the advantages of acetate glasses? The advantages of acetate glasses include:

Strong sense of fashion, rich colors and diverse patterns, easy to match with various clothes.

Thick texture, bright surface, stable frame, heavy feeling when wearing, giving people a high-grade feeling.

Skin-friendly and comfortable, smooth and warm surface, not easy to irritate the skin. Acetate fiber is an environmentally friendly material.

Durable and resistant to deformation, acetate fiber material has good toughness and is not easy to loosen after long-term use. And it is easy to adjust, and can be adjusted to the most comfortable state according to your face shape.

No metal structure, acetate glasses can use one-piece molding design to avoid metal allergies.

Metal glasses and metal sunglasses. 

Metal glasses are also one of the most popular types of glasses. Metal glasses are heavier than titanium glasses, and their strength and corrosion resistance are not as good as titanium glasses. The advantage is that they are much cheaper than titanium glasses. But why are metal glasses popular? The main reasons include:

Lightweight and durable: Compared with plastic glasses, plate glasses are made of metal materials (such as titanium alloy and stainless steel) with high strength and light weight, which are comfortable to wear and not easy to fatigue.

Exquisite design: It can create ultra-thin, minimalist or hollow shapes, suitable for business, leisure and other styles.

Strong plasticity: The temples and nose pads are easy to adjust to fit different face shapes and improve stability.

Corrosion resistance: The surface of metal glasses will be color-treated, such as electroplating or spraying. The electroplating process can also enhance the gloss and anti-allergic effect, so metal glasses are resistant to sweat oxidation. When making metal glasses, BESTSEA must pass a 78-hour sweat test.

Plastic glasses, including injection-molded glasses and TR glasses.

Injection-molded glasses. Made of injection-molded plastics, such as PC (polycarbonate), plastic steel or TR (memory plastic). These materials are melted and injected into the mold to cool and solidify, and have the characteristics of high dimensional stability and fast processing speed. Plastic glasses are relatively light and not easy to deform, but they are not heat-resistant, scratched, and have a short service life. In addition, the colors are not as rich as sheet glasses. In appearance, it is quite similar to sheet glasses, so how to distinguish them? Plastic frames are generally lighter, while sheet frames are heavier. By weighing the weight and touching the feel, you can preliminarily judge the material of the frame. Further observing the line traces, edge smoothness and other details of the frame, you can more accurately judge whether it is a plastic frame or a sheet frame. In terms of price, injection-molded glasses are also much cheaper.

 

TR90: This is a new material that has emerged in Korea this year. It is very light, soft, and harmless. It can be black or transparent. TR90 is the best in Korea. In many Korean dramas, those glasses that look very light are actually made of TR90. A lot of TR90 is also produced in China, and there have been great improvements in craftsmanship and materials. TR90 glasses are relatively low in cost, light, impact-resistant, and skin-friendly, but the disadvantage is that they are less stable and the color is relatively monotonous.

 

Buffalo horn glasses. 

horns are natural materials, mostly made of Indian buffalo horns, yellow cattle horns, Tibetan yak horns, etc. The texture and color of each pair of glasses are unique, similar to the experience of selecting jade, with artistic value and collection significance. Ox horn glasses have a unique texture. Because they are natural materials, they have no static electricity or allergic reactions when in contact with the skin, and are suitable for sensitive skin. They are relatively light and more suitable for long-term wear. The disadvantages are that they are relatively expensive and have high maintenance costs. They are afraid of high temperatures and falls, and are prone to brittle fractures in winter and cannot be repaired as before. Because they are natural materials, they are relatively hard and brittle. The curvature of the frame and the high precision of the temples are fixed at the factory and cannot be adjusted according to the face shape. In short, ox horn glasses are expensive due to the scarcity of materials, the unique texture of natural materials, and the complexity of the production process, and are considered a luxury among glasses.

Bamboo and wood glasses. 

Bamboo and wood glasses use bamboo or wood as the main material, and the production process is complex, with hundreds of processes. The advantages of bamboo and wood glasses are environmental protection, lightness, beauty, and toughness and durability. But the disadvantages may include difficulty in processing and easy breakage. It is relatively hard and generally comfortable to wear. Bamboo and wood glasses have occupied a place in the high-end eyewear market with their environmental protection properties, natural aesthetics and technological innovation, especially for consumers who pursue individuality and sustainable living. However, their process complexity and durability limitations still need to be further optimized. In the future, through the composite materials such as bamboo and wood + carbon fiber and functional integration (such as smart accessories), bamboo and wood glasses are expected to expand to a wider range of application scenarios.

Carbon fiber glasses.

 Carbon fiber glasses frames are a new type of glasses material that has appeared in recent years. Compared with traditional metal or plastic glasses frames, it has the advantage of being lighter, and it is also very strong, not easy to break or deform, and it also has a strong anti-oxidation effect. Due to its fine manufacturing process and high production process requirements, coupled with the high cost of the material itself, the price of carbon fiber glasses frames is generally high, which may be a bit expensive for ordinary consumers. The advantages and disadvantages of carbon fiber glasses frames are quite obvious. For consumers who choose carbon fiber glasses frames, they need to choose according to their own needs and preferences. If you focus on advantages such as lightness, durability, and anti-allergy, you can choose carbon fiber glasses frames; if you are sensitive to price, or are worried about fragility and deformation, choosing glasses frames made of other materials is also a good choice.
