What's the Best way to do Smelting? : r/SatisfactoryGame - reddit

The basic idea is to have your ores coming in at 60 then split to 30/30 for smelting then merge back into 60 out. The reason you want 60 out is because a lot of tier 1-3 constructor recipes can be overclocked to 20/40 inputs for efficiency so it makes for easier balancing post smelting. Anyway, hope that helps!
