The given diagram illustrates the process and equipment required for shaping glass containers.
Overall, the process consists of 9 steps. It begins with melting the glass and the process ends with packaging the final product.
Regarding the first half of the process, the glass is firstly melt in a furnace at 105C. The heated glass is then places into a mould. On the third stage, the hot glass is pressed with an iron presser. After, the shaped container is put into the second mould, while the walls of the container are still thick. Then, the air is blown into the container in order to form a final shape of the product.
On the sixth stage, the shaped container is heated in a kiln at 482C. In order for the product to cool after the whole process, the temperature in the Kiln iis lowered to the point of 25C; it stays in the Kiln for one hour. The final product is then reviewed by a factory worker for any potential imperfections. The containers that match the quality standards are then packed into boxes. In contrast, containers that do not meet the standards are put to waste. The whole process then repeats again.
