Glass bottles are manufactured through a series of steps. Firstly, a mixture of different raw materials is prepared and then placed in a furnace with high temperatures. These ingredients are melted down, resulting in a form of liquid glass. Next, the molten glass is cut into smaller segments using scissors. Each segment is carefully inserted into a machine that shapes them into a specific design using a mold. This process involves blowing air into the mold, which helps in creating the desired shape. To ensure the glass's stability and strength, the formed bottles are then annealed and cooled gradually. This gradual cooling process helps the glass to solidify and retain its shape, resulting in durable and functional glass bottles.
The detailed breakdown is as follows:
(2) Glass bottle production requires a diverse range of raw materials, with over ten types being used. Powdery materials are typically left untreated, but clinker (or cullet) must be cleansed to remove any metallic impurities. Once processed, the raw materials are mixed together in an even ratio before being placed into a kiln alongside a feeder.
The process of transforming raw materials into glass involves melting and clarification. The raw materials are gradually heated in a kiln at a temperature of approximately 1500 degrees until they melt and become a liquid resembling water. As this happens, impurities present in the raw materials slowly sink to the bottom of the kiln. As additional raw materials are added, the glass is further clarified and the purified liquid glass begins to flow into the material mouth. This process ensures that the resulting glass is of high quality and free from impurities.
Once the glass water reaches the material outlet, it flows into the material bowl and starts to cool down, leading to an increase in density and viscosity. At this stage, the feeder scissors cut the glass column with a specific weight and then transfer it to the lower mold through distinct material channels. Finally, these materials are subjected to compression or blowing using different machines. This process involves cutting and forming the glass into the desired shape, size, and weight, making it ready for further processing.
After the molded product goes through the scalder to release stress, it undergoes a gradual temperature drop until it reaches room temperature. Once it reaches the packaging room, the quality inspector carefully examines the products and removes any defective ones.
Once the finished products are packaged in various forms, they are transported by either manual handling or forklifts to a designated warehouse code for storage and delivery. This marks the final stage of production before the products are ready to be shipped to their respective destinations.
