The materials of glasses can be divided into: acetate glasses, plastic glasses, metal glasses, titanium frame glasses, horn glasses. At present, these five materials are more commonly used.
Acetate glasses material : Made of high-tech plastic memory board. Design: Tailor-made for fashionable people and students who pursue quality life.
Features: Simple and restrained design style, overall showing a steady side, using just the right coloring process. Emphasize the three-dimensional changes in the temple lines.
Accessories: The temples and foot covers are perfectly integrated, as if they were made in nature, and the shape of the lenses is highly personalized.
The main materials of plate glasses frames are: plate and plate plus steel.
Performance characteristics: Lighter, high hardness, good gloss, the combination with steel skin enhances the firmness, beautiful style, not easy to deform and discolor, and durable. It has a certain degree of elasticity. When it is bent or tightened with a little force and then relaxed, the shape memory plate will return to its original shape.
Frames cut from acetate sheets. The characteristics of the plate are that it is lighter, and the combination with the steel skin enhances the firmness, and the style is beautiful, not easy to deform and discolor, and is durable. It is not easy to burn, almost not discolored by ultraviolet rays, has greater hardness and better gloss, is not easy to be heated and processed, has a more beautiful style, and is not easy to deform after wearing.
Advantages: Plate frames are fashionable and easier to match with clothing. They combine the thickness of the plate with the metallic texture to reflect personality and style. The difference between plastic glasses and plates. Strictly speaking, the raw materials are basically the same, but the production processes are completely different. , the production process of memory plastic is similar to injection molding, but the polymer material is different from ordinary plastic. You can still find glasses made of memory plastic material on the market
Injection molding, both ordinary plastic and memory plastic are produced by this process. Grinding tools, and then melt the plastic material and inject it into the grinding tools to produce spectacle frames
Plates, the plastic is first formed into a plate through a pressing process, and then the spectacle frames are formed by cutting with CNC machine tools. In terms of density, Higher than ordinary plastic. Therefore, it is heavier and more durable. Since the plate is formed first, it can produce a variety of patterned colors, while the injection molding process can basically only produce single colors. The most important thing is that plastic glasses are cheaper than metal glasses. The metal frame depends on what material you choose. Needless to say, titanium is light, corrosion-resistant, not easy to fade, and not easy to deform. The alloy ones are economical and affordable, and generally last about a year. The high-nickel alloy ones are also good and won't deform easily, but they are a bit heavy. Metal frames generally look more elegant when worn
Glasses are now sold on the market in titanium frames, metal frames, plate frames and plastic frames. Pure titanium frames are of better quality and are not easy to fade. It is also relatively hard and not easily deformed. A pair of titanium frames can be worn for two or three years.
