Speed module — Factorio Production Calculator
Speed module is crafted in the assembling machine in 15 seconds, producing 1 per craft from 5 × Advanced circuit, 5 × Electronic circuit. At 60 per minute you need 30 assembling machines, and the chain behind it draws on 4 raw resources: petroleum gas, copper ore, iron ore, coal.
Production chain for 60 Speed module / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 3,900 | 32.5 | Assembling machine |
| Copper plate | 1,950 | 104 | Furnace |
| Electronic circuit | 900 | 15 | Assembling machine |
| Iron plate | 900 | 48 | Furnace |
| Plastic bar | 600 | 5 | Chemical plant |
| Advanced circuit | 300 | 60 | Assembling machine |
| Speed module | 60 | 30 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 6,000 |
| Copper ore | 1,950 |
| Iron ore | 900 |
| Coal | 300 |
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.
Speed module recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 15 s | 1 | Advanced circuit × 5, Electronic circuit × 5 |
What the whole chain needs
60 speed modules per minute pulls in 6 intermediate products, and the whole tree comes to 295 machines across 3 machine types, fed by 4 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 6,000 per minute, which is 6.67 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.

- Speed module 2 — 4 per craft
- Destroyer capsule — 1 per craft
What speed module is made from
- Advanced circuit — 5 per craft
- Electronic circuit — 5 per craft
FAQ
How many assembling machines do I need for 60 speed modules per minute?
30 assembling machines. One at standard speed produces 2 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 speed module take?
At 60/min the chain consumes 6,000 petroleum gas per minute, 1,950 copper ore per minute, 900 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is speed module needed for science packs?
Not directly. It feeds Assembling machine 3 and Speed module 2, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
