Abstract:
1. A method for operating a casting device including a die with cooling passages therein, through which a cooling medium is passed, comprising the steps of: casting parts in a production process while circulating cooling medium through the die at a first flow rate; completely stopping the flow of cooling medium through the die when ceasing the production of parts due to a production interruption; restarting the production process and casting at least two parts completely and consecutively within the die without circulating cooling medium through the die; after casting the at least two parts within the die without circulating cooling medium through the die, casting the next at least one additional part completely within the die while circulating cooling medium through the die at a rate less than the first flow rate; after casting the at least one additional part within the die while circulating cooling medium through the die at a rate less than the first flow rate, casting yet a further part within the die while circulating cooling medium through the die at the first flow rate.
