The provided diagram illustrates the process of shaping glass containers through a series of eight sequential steps.
Overall, the process involves melting glass in a furnace, pressing it into molds, blowing air to shape it, cooling in a kiln, further cooling, manual inspection, and disposal of rejected products.
Initially, glass is melted in a furnace at a high temperature of 1050°C and then pressed into Mould 1. Subsequently, it is transferred to Mould 2 to create a container with a thick wall. The container is then shaped by blowing air into it. Following this, the container goes through a cooling process in a kiln at 482°C. Afterward, it undergoes further cooling at room temperature for 60 minutes.
In the penultimate step, the glass containers are manually inspected, with accepted products receiving a success checkmark, while rejected items are discarded as waste. Finally, the approved glass containers are packaged in paper boxes.
