Flow production involves moving items continuously through the production process from one stage to the next without interruption. This allows for mass production of similar items at high volumes. Coca-Cola uses continuous flow production in its bottling process, where bottles move overhead from cleaning to filling to capping on an automated production line. The process involves cleaning and sanitizing bottles, filling them with water, sugar syrup, flavoring and carbonation using multiple steps, and capping the finished bottles for packaging. Continuous flow is well-suited to Coca-Cola's large production needs to meet worldwide demand for its various drink products.
