Based on a cycle rate of between 24 and 30 shots per hour at the die-casting machine, it is estimated that the hourly requirements for liquid copper will range between less than 140 kg/hr for the smaller rotors to nearly 1,300 kg/hour for the large rotors. More detailed estimates are shown in the Table below.

Motor Size Range		Liquid Copper Requirements (kg per hour)
KW	HP
Less than 1	Less than 1.3	Up to 140
1-5	1.3 to 6.5	90 to 225
5-20	6.6 to 26	140 to 550
20-50	26 to 66	440 to 1,300
