Some economic here, Total cost = fixed cost + variable cost. As long as the return is higher than variable cost, it helps to offset some of the fixed cost. This would help to boost profit or cut lost whichever you want to put it. Different kind of plants have different cost points. So again, the game here is to get the machine running 24 hours to boost profits, or to cut losses.

Infact you will find that some manufacturers will not look at you unless you talk runs of 1000000+++. Not for the people cost, but the plant cost
