How about the formula for the input and output of the cast aluminum rods?
Output = investment casting production scrap metal furnace non - loss of sawdust and other non recycled waste.
It's not clear whether your inputs and outputs are cost or metalIf it's metalOutput = cast furnace capacity - metal loss - Scrap (process quality scrap, scrap, sawdust, dry block, aluminum skin)
If that's the cost, it's good to count the money and the output.Input and output is not calculated, it should be statistical ah.
