Choose high-quality silica sand as the main raw material, as well as other auxiliary materials such as soda ash and limestone, to ensure the transparency and purity of the glass. Melting raw materials into uniform liquid glass in a high-temperature furnace requires precise control of temperature and time to avoid the mixing of impurities and the generation of bubbles.

There are three processes in molding technology. One is manual blowing, which involves blowing molten glass into a mold or shaping it by hand to form the desired cup shape. This step requires the operator to possess exceptional skills and experience. One method is mechanical pressing, which places liquid glass into a mold and forms it through pressure, suitable for producing glass cups with regular shapes. Another type is their combination - the combination of pressing and blowing, which first uses pressing to form the initial shape, and then adjusts the details through blowing to improve production efficiency and product quality. The formed glass cup needs to undergo a slow and uniform cooling process to prevent the generation of internal stress, which is crucial for the durability of the glass cup.

After cooling, the glass cup needs to be post-treated. Polishing and polishing: Remove burrs from the edges of the cup, making the surface smooth and enhancing the feel and aesthetics. Cutting and precision machining: Precisely cut the cup mouth to ensure that the size and shape meet the design requirements. After processing, quality inspection will be carried out on the glass cups, including appearance inspection, size measurement, weight testing, etc., to ensure that each product meets high standards. The final step is to package and transport the glass cups using appropriate packaging materials to ensure they are not damaged during transportation. And so a perfect glass appeared in your hand.
