Heavy armor — Factorio Production Calculator
Heavy armor is crafted in the assembling machine in 8 seconds, producing 1 per craft from 100 × Copper plate, 50 × Steel plate. At 60 per minute you need 16 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Heavy armor / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 15,000 | 800 | Furnace |
| Copper plate | 6,000 | 320 | Furnace |
| Steel plate | 3,000 | 800 | Furnace |
| Heavy armor | 60 | 16 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 15,000 |
| Copper ore | 6,000 |
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.
Heavy armor recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 8 s | 1 | Copper plate × 100, Steel plate × 50 |
What the whole chain needs
60 heavy armors per minute pulls in 3 intermediate products, and the whole tree comes to 1,936 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 15,000 per minute, which is 16.67 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 heavy armor
No base-game recipe consumes heavy armor — 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 heavy armor is made from
- Copper plate — 100 per craft
- Steel plate — 50 per craft
FAQ
How many assembling machines do I need for 60 heavy armors per minute?
16 assembling machines. One at standard speed produces 3.8 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 heavy armor take?
At 60/min the chain consumes 15,000 iron ore per minute, 6,000 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
