Acetate Glasses: Material, Benefits and Caring Tips

Are Acetate Frames Durable?

Yes, acetate frames can be durable. Acetate is a strong and durable material, which means it can withstand a certain amount of wear and tear. Compared to traditional plastic frames, they offer superior durability and flexibility. This makes them less likely to be damaged, and capable of providing a more comfortable fit. However, acetate is not unbreakable and it is important that people care for their glasses to ensure their longevity. Care instructions can be found alongside your acetate glasses purchase. Ensure you follow these to maintain their high quality.

Is Acetate a Lightweight Option for Eyeglasses Frames?

Yes, acetate is a lightweight option for eyeglasses frames. This makes it a comfortable eye glass frame perfect for prolonged wear. Unlike slightly heavier metals, acetate doesn’t put excess pressure on the bridge of the nose or temples. Acetate eyeglass frames are perfect for those who prefer a lighter frame on their faces.

Are Acetate Frames Eco-Friendly?

Acetate frames are eco-friendly in many aspects. Acetate is made from natural materials such as cotton and wood pulp which are biodegradable, unlike traditional plastic eyeglass frames. However their ability to biodegrade is highly dependent on the conditions in which the material is discarded, the added chemical structure in the material, and the finishes that have been applied to it. Therefore, it cannot be considered a completely eco-friendly material.

The production process of plastic eyewear

24-06-24 14:48:33    By Bestsea eyewear

Plastic eyewear are one of the most popular types of eyewear, including plastic frame glasses and plastic sunglasses. Plastic eyewear require mold production first, and then melted plastic is injected into the mold to form the glasses frame, So plastic eyewear are also called injection eyewear. This process is completed by an injection molding machine, and then a series of manual processes such as installing lenses are performed. Plastic eye frames have the advantages of light weight, strong stability, and a variety of styles, so they are deeply loved by consumers. However, the production process of plastic eyewear involves many steps and techniques. Let me briefly introduce them below.

The picture below shows a pair of two-tone plastic sunglasses. 1. Material selection for plastic eyewear. The frame part usually uses materials such as polycarbonate (PC), polyvinyl alcohol (PVA), and polypropylene (PP). The specific selection is determined by the design requirements and use environment of the glasses. PP, or polypropylene, is a widely used plastic that is often used to make glasses parts such as frames and nose bridges. PP has the characteristics of light weight, high strength, impact resistance, and high temperature resistance, making it one of the important materials in glasses production. TR90 plastic is a new type of thermoplastic elastomer and is also a popular glasses plastic at present. TR90 has the characteristics of soft material, wear resistance, high elasticity, and not easy to deform. Therefore, it is very suitable for making frames of complex shapes, especially for forming processing. In addition, TR90 has good transparency and is not easy to fade. It is also a very practical material. PC material is a high-strength, high-transparency, explosion-proof, and impact-resistant plastic material. It has both the lightness and high strength of plastic and the transparency and hardness of glass. It is a relatively excellent exoskeleton material. The advantage of this material is its high transparency and good protection against ultraviolet rays, sunlight, etc. At the same time, it has very good impact resistance and a strong protective effect on glasses frames and lenses, making it suitable for sports and daily wear.

Mold design: According to the design drawings of the plastic eyewear, the structure and size of the mold are formulated to ensure that each part of the glasses can be accurately injected. Mold manufacturing: The mold is usually made of metal (such as steel or aluminum), and processed and debugged according to the design requirements. High-quality plastic eyewear have high requirements for molds, including mirror treatment of the inside of the mold, so that the surface of the injected glasses is as bright as a mirror. 3. The production process of plastic eyewear. Here we will learn about the injection molding process of injection eyewear. This process is mainly completed by the injection molding machine. Preparation: Add the selected plastic raw material particles into the hopper of the injection molding machine. Heating and plasticizing: The raw materials are heated and plasticized in the injection molding machine to form a flowable molten plastic. Injection: The molten plastic is injected into the mold cavity through the nozzle. Cooling and solidification: Cooling in the mold to solidify the plastic into shape. Mold opening and removal: After the mold is opened, the molded glasses frame is taken out. 4. Spraying color on plastic eyewear. Plastic eyewear can be made by adding color powder to the plastic particles in advance according to the desired color, and then directly injection molding after sufficient stirring. However, if you want richer colors or add special effects, you can spray them after molding. Common spraying techniques include spray painting or vacuum coating. 5. Assembly of plastic glasses. After the frame is made, it is necessary to combine the frame with the temples, assemble the lenses, print characters, and other processes. 6. Finished product inspection of plastic eyewear. After assembly, the glasses must be 100% inspected, including appearance inspection and functional inspection. Appearance inspection: Check the appearance of the frames to ensure there are no flaws and defects. Functional inspection: Including functional performance inspections such as comfort, adaptability, and wear resistance of the glasses. Only when each pair of glasses can meet the specified quality standards can they be finally packaged and shipped. The picture below is a pair of black plastic sunglasses. In general, there are many processes for making plastic frame glasses, but every step is important, from selecting high-quality materials, making precise and smooth molds, strictly controlling the quality of the injection molding process, inspecting each pair of plastic frames and performing necessary manual processing, including manual polishing, until the final appearance and function inspection. We must pay attention to every detail of the production process in order to manufacture plastic glasses that satisfy customers.
