Unveiling the Miracle Behind the Secrets – The Birth of Tempered Glass Film Introduction: Have you ever been curious about how those resilient, scratch resistant, and wear-resistant phone screen protectors were born? Today, we will take you in depth to explore this seemingly simple yet complex process. Are you ready to enter the magical world together? Part 1: Selection of Raw Materials The raw material for tempered glass film is high-quality sodium calcium silicate glass, whose purity directly affects the quality of the final product. To ensure that each piece of glass meets strict standards, manufacturers need to carefully select and test the raw materials to ensure that they do not contain any impurities or bubbles. Part 2: Manufacturing and Cutting of Glass In modern factories, glass is rapidly cooled and solidified into a solid state after being melted at high temperatures in a furnace. This process requires precise control of temperature and time to avoid stress inside the glass, thereby maintaining its strength and transparency. Next, according to the customer’s needs, advanced CNC machine tools are used to cut large pieces of glass into small pieces of the required size. Part Three: Tempering Treatment The reason why tempered glass films are “tempered” is because they have undergone special strengthening treatment. This step is usually completed through heat treatment. Firstly, heat the ordinary glass to near the softening point, and then quickly immerse it in a low-temperature liquid for rapid cooling. This rapid heat exchange causes compressive stress to form on the surface of the glass, while tensile stress is generated internally, resulting in higher strength and impact resistance of the glass. Part 4: Chemical Hardening In addition to heat treatment, some high-end tempered glass films will also undergo additional chemical hardening treatment. This involves soaking the glass in a special solution, causing a chemical reaction on its surface to form a hard protective layer of silica. This can not only further improve the hardness of the glass, but also enhance its wear resistance and scratch resistance. Part 5: Coating Process In order to enhance the functional properties of tempered glass films, such as anti fingerprint and oil repellent effects, various types of coatings need to be added to their surfaces. For example, anti blue light coatings can filter harmful shortwave blue light; Explosion proof coating can prevent fragments from splashing in case of accidental rupture, protecting user safety. Part 6: After each step of quality inspection is completed, a strict quality inspection process is required. From visual inspection to thickness measurement, and then to testing of transmittance, hardness, and scratch resistance, every detail cannot be overlooked. Only products that have passed all these rigorous tests can be labeled as qualified and sent to the market for sale. Part 7: Packaging and Shipping. Finally, the qualified tempered glass film will be carefully packaged to prevent damage during transportation. Whether by express delivery or sea freight, it is important to ensure that the product arrives in perfect condition and reaches the hands of consumers. Conclusion: Through the complex and precise operation process mentioned above, we finally understand why a small tempered glass film can be so sturdy and versatile. From the selection of raw materials to the final packaging, every step must strive for excellence. It is precisely this spirit of craftsmanship that provides the best protection for our mobile phone screens. Now that you know the mystery behind it, will there be a brand new respect next time you put on a new film for your phone?
