Express splitter — Factorio Production Calculator
Express splitter is crafted in the assembling machine in 2 seconds, producing 1 per craft from 1 × Fast splitter, 10 × Iron gear wheel, 10 × Advanced circuit, 80 × Lubricant. At 60 per minute you need 4 assembling machines, and the chain behind it draws on 5 raw resources: petroleum gas, iron ore, heavy oil, copper ore, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 12,000 |
| Iron ore | 5,160 |
| Heavy oil | 4,800 |
| Copper ore | 4,350 |
| Coal | 600 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Express splitter recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 2 s | 1 | Fast splitter × 1, Iron gear wheel × 10, Advanced circuit × 10, Lubricant × 80 |
What the whole chain needs
60 express splitters per minute pulls in 11 intermediate products, and the whole tree comes to 787 machines across 3 machine types, fed by 5 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 12,000 per minute, which is 13.33 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses express splitter
No base-game recipe consumes express splitter — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What express splitter is made from
- Fast splitter — 1 per craft
- Iron gear wheel — 10 per craft
- Advanced circuit — 10 per craft
- Lubricant — 80 per craft
FAQ
How many assembling machines do I need for 60 express splitters per minute?
4 assembling machines. One at standard speed produces 15 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does express splitter take?
At 60/min the chain consumes 12,000 petroleum gas per minute, 5,160 iron ore per minute, 4,800 heavy oil per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
