Sow casting automated guided vehicle

A method for producing sows from liquid metal cast into moulds, the method comprises:

• providing a number of at least three stations, each one of the stations adapted for performing one of different tasks in the producing of the sows, each one of the stations having one or more dedicated positions and operating at a dedicated rate in terms of number of sows per time unit, wherein, during the producing of the sows, tasks relative to producing sows are performed in a preset order;
• providing a plurality of moulds movable independently to one another between the dedicated one or more dedicated positions of the stations;
• and
• providing a number of Automated Guided Vehicles (AGVs) moving independently from one another between the stations, each one of the AGVs being able to move one of the moulds from a first position being any one of the dedicated positions of the stations to a second position being any other one of the dedicated position of the stations,
• wherein each one of the AGVs is moving independently from each other, each one of the AGVs moving according to a path selected from a plurality of paths.
