Constant combinator — Factorio Production Calculator
Constant combinator is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 5 × Copper cable, 2 × Electronic circuit. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 2 raw resources: copper ore, iron ore.
Production chain for 60 Constant combinator / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 660 | 5.5 | Assembling machine |
| Copper plate | 330 | 17.6 | Furnace |
| Electronic circuit | 120 | 2 | Assembling machine |
| Iron plate | 120 | 6.4 | Furnace |
| Constant combinator | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Copper ore | 330 |
| Iron ore | 120 |
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.
Constant combinator recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Copper cable × 5, Electronic circuit × 2 |
What the whole chain needs
60 constant combinators per minute pulls in 4 intermediate products, and the whole tree comes to 33 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 330 per minute, which is 0.37 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 constant combinator
No base-game recipe consumes constant combinator — 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 constant combinator is made from
- Copper cable — 5 per craft
- Electronic circuit — 2 per craft
FAQ
How many assembling machines do I need for 60 constant combinators per minute?
1 assembling machine. One at standard speed produces 60 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 constant combinator take?
At 60/min the chain consumes 330 copper ore per minute, 120 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Machine counts assume bare machines at standard speed. Recipe data comes from the game's own prototypes (PlayerCalc, Factorio 2.0 base game). Not affiliated with Wube Software.
