Belt immunity equipment — Factorio Production Calculator
Belt immunity equipment 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 Belt immunity equipment / 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 |
| Belt immunity equipment | 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.
Belt immunity equipment recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Advanced circuit × 5, Steel plate × 10 |
What the whole chain needs
60 belt immunity equipments 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 belt immunity equipment
No base-game recipe consumes belt immunity equipment — 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 belt immunity equipment is made from
- Advanced circuit — 5 per craft

FAQ
How many assembling machines do I need for 60 belt immunity equipments 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 belt immunity equipment 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.
