Plastic bar — Factorio Production Calculator
Plastic bar is crafted in the chemical plant in 1 seconds, producing 2 per craft from 20 × Petroleum gas, 1 × Coal. At 60 per minute you need 0.5 chemical plants, and the chain behind it draws on 2 raw resources: petroleum gas, coal.
Production chain for 60 Plastic bar / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Plastic bar | 60 | 0.5 | Chemical plant |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 600 |
| Coal | 30 |
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.
Plastic bar recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Chemical plant | 1 s | 2 | Petroleum gas × 20, Coal × 1 |
What the whole chain needs
This recipe has no intermediate steps: every ingredient is a raw resource, so the chain is a single machine block fed straight from mining or pumpjacks. At 60 per minute that is 1 machines and nothing else to build.
Belt check: the busiest input here moves 600 per minute, which is 0.67 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 plastic bar
4 base-game recipes consume plastic bar, sorted by how much each one takes:
- Low density structure — 5 per craft
- Advanced circuit — 2 per craft
- Cannon shell — 2 per craft
- Explosive cannon shell — 2 per craft
FAQ
How many chemical plants do I need for 60 plastic bars per minute?
0.5 chemical plants. One at standard speed produces 120 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 plastic bar take?
At 60/min the chain consumes 600 petroleum gas per minute, 30 coal per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is plastic bar needed for science packs?
Not directly. It feeds Low density structure and Advanced circuit, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
