Energy shield — Factorio Production Calculator
Energy shield is crafted in the assembling machine in 10 seconds, producing 1 per craft from 5 × Advanced circuit, 10 × Steel plate. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 4 raw resources: petroleum gas, iron ore, copper ore, coal.
Production chain for 60 Energy shield / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 3,600 | 192 | Furnace |
| Copper cable | 3,000 | 25 | Assembling machine |
| Copper plate | 1,500 | 80 | Furnace |
| Electronic circuit | 600 | 10 | Assembling machine |
| Plastic bar | 600 | 5 | Chemical plant |
| Steel plate | 600 | 160 | Furnace |
| Advanced circuit | 300 | 60 | Assembling machine |
| Energy shield | 60 | 20 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 6,000 |
| Iron ore | 3,600 |
| Copper ore | 1,500 |
| 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.

| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Advanced circuit × 5, Steel plate × 10 |
What the whole chain needs
60 energy shields per minute pulls in 7 intermediate products, and the whole tree comes to 552 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.
What uses energy shield
1 base-game recipe consumes energy shield, sorted by how much each one takes:

What energy shield is made from
- Advanced circuit — 5 per craft
- Steel plate — 10 per craft
FAQ
How many assembling machines do I need for 60 energy shields per minute?
20 assembling machines. One at standard speed produces 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 energy shield take?
At 60/min the chain consumes 6,000 petroleum gas per minute, 3,600 iron ore per minute, 1,500 copper ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is energy shield needed for science packs?
Not directly. It feeds Energy shield MK2, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
