Fast splitter — Factorio Production Calculator
Fast splitter is crafted in the assembling machine in 2 seconds, producing 1 per craft from 1 × Splitter, 10 × Iron gear wheel, 10 × Electronic circuit. At 60 per minute you need 4 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Fast splitter / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 2,760 | 147.2 | Furnace |
| Copper cable | 2,700 | 22.5 | Assembling machine |
| Copper plate | 1,350 | 72 | Furnace |
| Electronic circuit | 900 | 15 | Assembling machine |
| Iron gear wheel | 720 | 12 | Assembling machine |
| Transport belt | 240 | 2 | Assembling machine |
| Fast splitter | 60 | 4 | Assembling machine |
| Splitter | 60 | 2 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 2,760 |
| Copper ore | 1,350 |
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.
Fast splitter recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 2 s | 1 | Splitter × 1, Iron gear wheel × 10, Electronic circuit × 10 |
What the whole chain needs
60 fast splitters per minute pulls in 7 intermediate products, and the whole tree comes to 277 machines across 2 machine types, fed by 2 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 2,760 per minute, which is 3.07 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 fast splitter
1 base-game recipe consumes fast splitter, sorted by how much each one takes:

What fast splitter is made from
- Splitter — 1 per craft
- Iron gear wheel — 10 per craft
- Electronic circuit — 10 per craft
FAQ
How many assembling machines do I need for 60 fast 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 fast splitter take?
At 60/min the chain consumes 2,760 iron ore per minute, 1,350 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is fast splitter needed for science packs?
Not directly. It feeds Express splitter, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
