In the selection of raw materials, we insist on using high-quality eva material, which not only has excellent flexibility, but also has good cushioning properties, which can effectively resist the collision and extrusion in daily use, and provide a reliable protective barrier for glasses. At the same time, eva material also has the characteristics of waterproof, moisture-proof and dust-proof, avoiding the damage to glasses caused by moisture, dust and other factors, and prolonging the service life of glasses.

In terms of production process, the factory has advanced production equipment and mature technology. From the initial mold design to the final product molding, every link is strictly controlled. Precise mold design ensures that the glasses cases produced are of precise size and fit well. During the molding process, the precise control of temperature, pressure and other parameters ensures that the performance of eva material is given full play to make the eyeglass cases have good hardness and stability. In addition, the factory also pays attention to the details, such as the polishing of the edges and the quality of the stitching, etc., and strives to make every eyeglass case exquisite and perfect.
