This article describes the basics of setting up production lines, how to read the UI of buildings (such as input and output item rates), and how to calculate the buildings ratio.

Reading buildings' interface[edit | edit source]

A simple production line, showing the UI of each building. (Click to enlarge)

A simple production line involves Miner -> Smelter -> Constructor -> Storage Container. In this example, all the buildings are in 1:1 ratio, as the item production and consumption rates are matched up perfectly (marked in red). Below each building is their UI, which can be accessed by standing near to a building then interact E with it.

Miner[edit | edit source]

Miner extracts ores at a rate which depends on both the resource node's purity and the Miner's mark. The resource node's purity, either impure, normal or pure is fixed based on its location on the map. Higher marks of Miner can be unlocked at later Milestones which improve mining rate. In this example the Miner Mk.1 extracts 30 Iron Ores / min from the resource node below it.

Smelter[edit | edit source]

Smelter converts Ores into Ingots. In the above example, 30 Iron Ores are consumed every minute to produce 30 Iron Ingots every minute.

Constructor[edit | edit source]

Constructor crafts useful items out of Ingots. In the above example, every 3 Iron Ingots are consumed to craft 2 Iron Plates, notice the items after the Constructor are produced in groups of two. These numbers can be ignored in automated setups, as we should be looking for item consumption and production rates. The smaller numbers below the bold texts are the rates - 30 Iron Ingots are consumed per minute and 20 Iron Plates are produced per minute.

Looking at the crafting ratio (the bold texts), we can deduce that each Iron Plate requires 1.5 Iron Ingots to craft.
3 / 2 = 1.5

Conveyor Belt[edit | edit source]

Conveyor Belts automatically transport items from one buildings to the next so you don't have to manually carry the items all the time. They have a rated item flow rate, so if higher item flow rate is required, consider using higher marks of Conveyor Belts, or by constructing multiple parallel belts. Else, the entire production line may get slowed down due to insufficient item flow.

Storage Container[edit | edit source]

The Storage Container in the above example is optional. Its purpose to store and buffer produced items so that the machines before it can run smoothly. Most of the production buildings can only store up to 1 stack of items at its output slot, and once it is full, the machine stops.

Overclocking[edit | edit source]

The speed of all the above machines can be altered with overclocking, which will be discussed in the section below.

Splitting and merging[edit | edit source]

Splitters and Mergers may be required to achieve 100% efficiency in some setup, such as for the Copper chain. (Click to enlarge)

Production chains rarely work in 1:1 building ratio; the example shown in the previous section is just a special case. If there is a mismatch in the buildings' ratio, the entire chain is slowed down proportionally to the slowest element in the chain. This reduces the efficiency and should be avoided.

To achieve 100% efficiency (as indicated by the '100%' at the lower right of each machine's UI), make sure the production rate from one machine matches the consumption rate of the next machine. And if they don't match, just build more machines until the numbers match.

The term 'Efficiency' is used to describe the uptime of a machine, usually denoted in percentage (%).

Miner[edit | edit source]

A Miner Mk.1 on a normal Copper node extracts Copper Ores at 60/min.

Smelter[edit | edit source]

A Smelter consumes Copper Ores at only 30/min. To achieve 60/min consumption, build 2 of them. Use a Splitter to split the Conveyor Belt into two.
60 / 30 = 2

If only 1 Smelter is built, the Copper Ores produced by the Miner will not be consumed fast enough, and they will backlog into the Miner and causing it to run at only 50% of the time. This is equivalent to 50% efficiency.

Each Smelter produces Copper Ingots at 30/min.

Constructor (Wire)[edit | edit source]

Each Constructor consumes Copper Ingots at only 15/min. Similarly, split each of the Copper Ingot belt into two, this means 4 Constructors are required.
30 / 15 = 2 (each Smelter output belt split into two)
2 x 2 = 4 (2 Smelters support 4 Constructors)

Each Constructor produces Wires at 30/min.

Constructor (Cable)[edit | edit source]

Each Constructor consumes Wires at 60/min. That means the Wires from a single Constructor will not be enough - we need two. To combine the output of two Constructors, use a Merger.
30 * 2 = 60

If only 1 Constructor crafting Wires is connected to the Constructor crafting Cable, the latter will only run at 50% of the time due insufficient input rate. This is equivalent to 50% efficiency.

Each Constructor produces Cables at 30/min.

Conveyor Belt[edit | edit source]

Conveyor Belt Mk.1 can only transport 60 items/min. In the above example, the belt carrying Copper Ores after the Miner, and the belts transporting Wires after the Mergers are operating at their maximum capacity.

Storage Container[edit | edit source]

A Storage Container is used to store each type of item. As a good practice, avoid mixing items in Storage Containers. A Merger is used to merge 2 Wire belts into 1 before the Container so that you don't have to build 2 Containers for Wires.

Overclocking and belt speed[edit | edit source]

An overclocked Miner extracts ores faster, and thus capable to supply more Smelters. (Click to enlarge)
The overclocking section in a building's UI. (Click to enlarge)
Main article: Clock Speed

As the number of resource nodes in the world is finite, there is a hard limit on the total extraction rate. To maximize the potential of a resource node, Miners should be Overclocked. The overclocking ability can be researched in M.A.M..

Miner[edit | edit source]

The Miner Mk.1 on a normal Iron node in the above example is overclocked to 250% (x 2.5 speed), hence it extracts Ores at 150/min.
60 x 2.5 = 150

Smelter[edit | edit source]

Each Smelter consumes 30 Iron Ores / min to yield 30 Iron Ingots / min. Five (5) Smelters should be built to fully utilize the extracted Ores.
150 / 30 = 5

Conveyor Belt[edit | edit source]

Main article: Conveyor Belt

Conveyor Belt Mk.1 is not fast enough (60 items/min) to pull out all the ores extracted by the overclocked Miner (150 items/min), thus higher marks of belt are required. Else, the Miner will not run at its overclocked potential.

Conveyor Belt Mk.3 can handle the 150/min item flow rate and should be built right after the Miner. Where the item flow rates are between 120/min and 60/min, Conveyor Belt Mk.2 should be used. The remaining belts can be built as Mk.1. Alternatively, all belts can be built with Conveyor Belt Mk.3, if there is sufficient material to do so.

Splitter[edit | edit source]

Splitters are built in a manifold style. Each split takes away the machine consumption rate from the main belt or half of the incoming item speed, whichever is lesser (see the yellow numbers beside the belt). The last Splitter at the far left is optional; it is built for future expansions, when higher marks of Miner are unlocked. Plus they look neater.

Fractions and decimals[edit | edit source]

A normal, Limestone Miner can support more than 1, but less than 2 Constructors. (Click to enlarge)

There are many occasions where the building ratio doesn't end up as integers. The Limestone -> Concrete setup, for instance, is the first production chain that contains fractional ratio:
60 / 45 = 1.333 or 1+1/3
The Limestones produced by a normal Miner can support 1.333... Constructors.

Obviously we can't build 0.333 machine, so 2 Constructors should be built to fully consume the Limestone produced by the Miner. But then 2 Constructors require 90 Limestones / min.

Let's see a few approaches to solve this issue:

Underclock the last machine[edit | edit source]

Underclock the 2nd Constructor to 34% is the closest form we can achieve the 1.333... ratio. Do not underclock it to 33%, as we will lose the 0.33% processing speed. Take note Clock Speed can only be set to integers of percentage.

Underclock all machines[edit | edit source]

Underclock both Constructors to 67% has the benefit of improved power saving compared to the previous method. You can examine the power consumption of each underclocked building and add them up.
1.3333 / 2 = 0.6666 = 67%

Skip underclocking[edit | edit source]

Not underclock any of the Constructor works just fine. In general, any decimal in building ratio can be simply rounded up to the next integer, for example:
60 / 45 = 1.333 -> 2

400 / 30 = 13.33 -> 14

100 / 110 = 0.909 -> 1

In the above example, if both Constructors are not underclocked, they will just run and stop intermittently, but still effectively converts 60 Limestones / min to 20 Concretes / min. The difference is, underclock reduces power consumption. This method can be used before the Overclocking ability is unlocked.

Overclock the Miner[edit | edit source]

Overclock the Miner to 150% or 225% will make the ratio becomes integer.
45 x 2 = 90
90 / 60 = 1.5 (150% overclock, 1 Miner to 2 Constructors)


45 x 3 = 135
135 / 60 = 2.25 (225% overclock, 1 Miner to 3 Constructors)

Overclock the Constructor[edit | edit source]

Only build one (1) Constructor and overclock it to 134% allows all the Limestone to be consumed effectively. Take note as Power Shard is a limited resource, this method is not recommended.

Complex production line[edit | edit source]

A working Reinforced Iron Plate production with incorrect building ratios. (Click to enlarge)

Reinforced Iron Plate, for example, consists of more than 1 ingredient. In the above image, the buildings are set up based on 1:1 ratio. This setup still works, but with lower efficiency due to incorrect building ratio. Lets examine each of the components:

Miner[edit | edit source]

Miner Mk.1 on a pure Iron node extracts 120 Iron Ores / min. Pure nodes are quite common in Northern Forest and they yield double rate. The Conveyor Belt Mk.1 after it is not fast enough and should be replaced with Conveyor Belt Mk.2.

Smelter[edit | edit source]

A Smelter consumes 30 Iron Ores / min and produces 30 Iron Ingots / min. So, this Miner can support 4 Smelters.
120 / 30 = 4

Splitting - question[edit | edit source]

Here is the problem. Iron Ingots are to be split among Iron Rods and Iron Plates, but we don't know the ratio between them. To solve this, we can use the top-down method: start from the end product, then work backwards to its raw ingredients.

Reinforced Iron Plate[edit | edit source]

The Assembler crafting Reinforced Iron Plates, or RIP, needs Iron Plates at 30/min and Screws at 60/min. If either of the ingredients faces shortage, the entire chain will be slowed down.

Iron Plate[edit | edit source]

In the previous section, we have learnt that each Iron Plate requires 1.5 Iron Ingots to craft. To produce 30 Iron Plates / min, 45 Iron Ingots / min is required.
30 * 1.5 = 45

Screw[edit | edit source]

Each Iron Rod can be crafted into 4 Screws. That means 60 Screws / min requires 15 Iron Rods / min.
60 / 4 = 15

Iron Rod[edit | edit source]

Each Iron Rod is crafted from one (1) Iron Ingot; the ratio is 1:1. That means 15 Iron Ingots / min is required to craft 15 Iron Rods / min.

Splitting - conclusion[edit | edit source]

For each minute, 45 Iron Ingots should be allocated to Iron Plates and 15 Iron Ingots should be allocated to Iron Rods. The total consumption would be 60 Iron Ingots / min.
45 + 15 = 60

By dividing those number by a common divisor, the ratio can be simplified to 3:1. That means, 3 quarter of the Iron Ingot goes to the Iron Plate and a quarter goes to Iron Rod.
45 : 15 == 1 : 3 (divide both by 15)

The Miner above has the capability to produce 120 Iron Ores / min, which can be crafted into 120 Iron Ingots / min. This means up to 2 Assemblers crafting Reinforced Iron Plates can be supported.
120 / 60 = 2

With these numbers, we can work from bottom-up, reversing the calculation process, then multiply the setup by 2. From here and below, we omit the word 'per minute' for simplicity.

Constructor (Iron Plate)[edit | edit source]

45 x 2 = 90
90 Iron Ingots are used to craft 60 Iron Plates. Three (3) Constructors are required.
90 / 30 = 3

Constructor (Iron Rod)[edit | edit source]

15 x 2 = 30
30 Iron Ingots are used to craft 30 Iron Rods. Two (2) Constructors are required.

Constructor (Screw)[edit | edit source]

60 x 2 = 120
30 Iron Rods are used to craft 120 Screws. Three (3) Constructors are required.
120 / 40 = 3

Assembler (RIP)[edit | edit source]

Two Assemblers are required to craft the RIP.

Conveyor Belt[edit | edit source]

We will use Splitters and Mergers to distribute the items. Identify which belts will carry more than 60/min, and construct them with Conveyor Belt Mk.2 or above.

Satisfactory Calculators[edit | edit source]

There are various online tools to help you to find out the quantity of buildings if you don't want to calculate yourself.
