Production science pack — Factorio Production Calculator
Production science pack is crafted in the assembling machine in 21 seconds, producing 3 per craft from 1 × Electric furnace, 1 × Productivity module, 30 × Rail. At 60 per minute you need 14 assembling machines, and the chain behind it draws on 5 raw resources: petroleum gas, iron ore, copper ore, stone, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 4,000 |
| Iron ore | 3,150 |
| Copper ore | 1,150 |
| Stone | 700 |
| Coal | 200 |
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.
Production science pack recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 21 s | 3 | Electric furnace × 1, Productivity module × 1, Rail × 30 |
What the whole chain needs
60 production science packs per minute pulls in 12 intermediate products, and the whole tree comes to 479 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 4,000 per minute, which is 4.44 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 production science pack
No base-game recipe consumes production science pack — 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 production science pack is made from
- Electric furnace — 1 per craft
- Productivity module — 1 per craft
- Rail — 30 per craft
FAQ
How many assembling machines do I need for 60 production science packs per minute?
14 assembling machines. One at standard speed produces 4.3 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 production science pack take?
At 60/min the chain consumes 4,000 petroleum gas per minute, 3,150 iron ore per minute, 1,150 copper ore per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
