Heavy Modular Frame Production

Learn how to produce Heavy Modular Frames in Satisfactory. This guide covers the necessary components and efficient factory setup to automate this crucial mid-game item.

Alright, let's talk about the Heavy Modular Frame. This is a big step up from the early game, and getting a solid production line for these going is key to progressing further into Tier 3 and beyond. Think of it as the next major hurdle after you've got your basic iron and copper production sorted.

The Heavy Modular Frame is a pretty significant item because it unlocks a bunch of important stuff, like the Space Elevator, and it's a core component for more advanced buildings and vehicles. You'll be making a lot of these, so setting up an efficient factory for them now will save you a ton of time later.

What you'll need to get started:

• Iron Rods: You'll be making these by the hundreds, so make sure your Iron Rod production is already humming.
• Screws: These are also a major component. You'll need a dedicated Screw production line, likely using the Alternate: Smart Plating or another efficient method if you've unlocked it.
• Modular Frames: Yes, you need the basic Modular Frames to craft the Heavy ones. This means you'll need a steady supply of Iron Rods and Screws feeding into a Constructor making Modular Frames.
• Concrete: This is made from Raw Concrete, which in turn is made from Limestone. You'll need a steady supply of this too.

Setting up the production:

The Heavy Modular Frame recipe itself is pretty straightforward: 2x Modular Frames + 2x Concrete.

You'll need a Constructor to make the Heavy Modular Frames. The base recipe gives you 1 Heavy Modular Frame every 6 seconds (10 per minute). This might seem slow, but remember you'll likely be running multiple Constructors for this.

Here’s a common setup:

1. Input: Have your Iron Rods, Screws, and Concrete delivered to the area where you'll be building your Heavy Modular Frame Constructors. Use Conveyor Belts to bring them in.
2. Modular Frame Production: If you haven't already, set up a Constructor dedicated to making Modular Frames. This recipe is 3x Iron Rods + 6x Screws, yielding 1 Modular Frame every 6 seconds (10 per minute). You'll need to feed this Constructor with Iron Rods and Screws.
3. Concrete Production: Similarly, ensure you have a Constructor making Concrete. The recipe is 30x Raw Concrete (made from 10x Limestone) yielding 10x Concrete every 6 seconds (100 per minute). You'll need to feed this with Raw Concrete.
4. Heavy Modular Frame Constructors: Now, place your Constructors for the Heavy Modular Frames. Each one will take 1x Modular Frame and 1x Concrete per minute (based on the 6-second cycle for 10/min output). Since the recipe is 2x Modular Frames + 2x Concrete, you'll need to balance your inputs. A good starting point is to have one Constructor dedicated to Modular Frames and another to Concrete, and then feed those outputs into your Heavy Modular Frame Constructors.

Balancing the numbers:

This is where it gets a bit more involved. Let's break down the inputs for one Heavy Modular Frame Constructor running at full speed (10 per minute):

• It needs 20x Modular Frames per minute.
• It needs 20x Concrete per minute.

To get 20x Modular Frames per minute, you'll need two Constructors making Modular Frames (each making 10/min). Each of those needs 30x Iron Rods/min and 60x Screws/min. So, for just *one* Heavy Modular Frame Constructor, you're looking at needing 60x Iron Rods/min and 120x Screws/min!

For the Concrete side, to get 20x Concrete per minute, you'll need two Constructors making Concrete (each making 10/min). Each of those needs 60x Raw Concrete/min (which comes from 20x Limestone/min). So, for *one* Heavy Modular Frame Constructor, you're also looking at needing 60x Raw Concrete/min (or 20x Limestone/min).

Pro-Tip: This is why you see players build massive factories. You'll likely want to dedicate a whole area to just producing the components for Heavy Modular Frames. Start with one Heavy Modular Frame Constructor and scale up as your resource gathering and production lines can support it. Don't be afraid to overproduce the intermediate components like Iron Rods, Screws, and Concrete, as they're used in tons of other recipes!
