Unified Foundry

Author: Calen
Built for Update 3
vU3.2.0

Description

The Unified Foundry provides a single facility to produce everything that utilizes a molten channel. It is designed for use from mid to end game. The modules of the Unified Foundry are designed to link seamlessly together. Therefore, it is very important to read the installation instructions for each blueprint in order to properly place each blueprint.

Note: Installation images and instructions can be found here: https://imgur.com/a/unified-foundry-installation-instructions-3ZU4SUY.

Stages of the Unified Foundry:

  • Stage 1: Initial Build for Iron, Steel, Copper, Glass Smelting, & Recycling
  • Stage 2: Silicon Production
  • Stage 3: Cooling Tower Upgrade
  • Stage 4: Gold Smelting
  • Stage 5: Glass II Upgrade
  • Stage 6: Arc Furnace II Upgrade for Silicon
  • Stage 7: Arc Furnace II Upgrade for Everything Else
  • Stage 8: Aluminum Smelting
  • Stage 9: Titanium Alloy Smelting

Note: Due to the COI:Hub size limit of 100k per blueprint upload, I am unable to include a completed build with the Unified Foundry. I have created a separate blueprint though, which you can get here: https://hub.coigame.com/Blueprint/Detail/997.

Transport

My current transport modus operandi is to use trains to transport ore processed at the mines and use belts & pipes for transport between factories. However, I understand that some of you prefer to only use belts & pipes. As such, I have included two options for ingress transport: belts & pipes only or hybrid (train station for ore with belts & pipes for the rest). Egress also has two options, they are "normal" or flipped. If products leave the one side of the Unified Foundry and enter the Manufacturing Hub on its opposing side (e.g.: products leave the UF on the left and enter the MH on its right side, or vice versa) then use the "normal" egress transport. If you use the same side for each, use the flipped blueprint.

Both ingress and egress transports have a hookup blueprint which includes initial belts and pipes passing under vehicle ramps. These must be placed first.

Tips

  1. Use the UF Footprint Guide blueprint to make sure you have enough space.
  2. Start with constructing the pipes, conveyors, and storage first. Then construct the production buildings as needed.
  3. Upgrade conveyors to tier III as needed and able.

Zapatosh
Nice Job, I really like your Blueprints, this one but also the others. Keep it up.
Calen
Thanks, Zapatosh!
PiggyWhiskey
Any chance of getting a final stage complete blueprint? I keep messing up the Copper/Iron/Steel upgrade to Arc Furnace 2
Calen (edited)
@PiggyWhiskey - So... as it turns out, when I changed the piping for the large cooling tower above the gold foundry, I did not update the arc furnace II steam piping for the glass furnaces. Perhaps that was your issue? This has now been fixed. However, if you were still having difficulties (understandable since it's a complicated upgrade), I have added images here: https://imgur.com/a/yX0XgXR. Lastly, I did update this blueprint with a completed build.
KT9Q (edited)
Given how much sulfur this produces because of the exhaust scrubbers plus how much acid it needs its a shame there's not a couple of mixers built in to internalize the production of it. Here is an upgrade to solve that: https://hub.coigame.com/Blueprint/Detail/423 Feel free to do whatever with it.
Calen (edited)
@KT9Q - Good idea! I hadn't thought about that. I think the reason I hadn't is because I build an entire conveyor network for sulfur on my island. So in my games I'm not wasting it, I'm just shipping it elsewhere for processing into acid. But I really like the idea of processing it on site. I'll need another ingress water pipe for the water needed for mixers. I could use the former acid ingress pipe, although I may still need that if sulfur production doesn't meet acid needs. I'll bet there are scenarios where it doesn't. Also, where do I put the mixers? Your blueprint works for pre 2.2 builds, but after 2.2 the recycling module is in the way. I will ponder. Thanks again for the good idea.
Djinsomnia
Hey, love the Blueprint works amazingly - Found a single pipe missing on the steam/Cooling tower lines between the exhaust scrubbers and cooling towers. Took me an hour to figure out why everything was full of steam and cooling towers weren't working lol
Calen
@Djinsomnia - I'm not seeing this problem. It could have been a misplacement or small unevenness of the ground, both of which have happened to me.
abn1304
@Calen: Question for you. It looks to me like the MH outputs for the Foundry don't match up with the transports/inputs for the MH. What am I missing? Thanks! Love your blueprints - excellent work.
CaptainOfChaos
I ran into the same issue as Djinsomnia with the missing pipe, fwiw it only concerns the complete build, not if you build it in steps. The low steam pipe inputs are going into a balancer near the 4 cooling towers and there is a single piece of pipe missing for the output to the cooling towers. No biggie but easy to miss. Thanks for all the blueprints Calen and big compliments for the layouts and clear instructions! <3
adsyde
Awesome job!
Skellitor301
If this is meant to plug into your manufacturing hub, where is the carbon dioxide and slag meant to go? The pipes in the egress blueprints for these lines are not the same as the ones for the manufacturing hub and its transport belts. The manufacturing hubs lines are flat transports on those sections.
Persox
Impossible to copy the link.. :/
Степан
обновите до новой версии! (чертеж не работает, нельзя построить)
Calen
@Persox & @Степан - I just tested copying the blueprint, pasting it into COI, and building it. Everything seems fine to me.
MaddTrker
I went to use this BP, and realized that the Ingress transport doesn't mach up to the ingress ports for theGraphite, and Coal storage boxes. The belt that is there is a flat belt and not a u-shape belt, plus the two graphite belts are U-shape belts, and not flat belts.
zack12027
good stuff, im surprised it didn't have ore crusher at the very beginning
Calen
@MaddTrker - The ingress transport works fine for me. Remember there are belts & pipes for modules not yet installed at the beginning. You can anchor via the water pipe, which is the 3 transport from the right (or left if you flipped the foundry & ingress transport).
Calen
@zack12027 - I have those as separate blueprints (in the Peripherals subfolder) so you can place them wherever you want. I usually place them near the relevant mines or depots.
halcyforn
this is not bad but can you make a version where first stages are separate for early game ? im saying about main complex this is huge but given time we can start early and upgrade it or start building it
Calen
@halcyforn - I actually have a smaller version for the early game called Early Foundry.
halcyforn
@Calen you didnt understand this one is ok but i ask if you can just split first part with basic iron, copper steel, glass, for people who dont want build first early but want start build this one on start.
Skellitor301
@halcyforn Again, that's what the other blueprint is for. You're not supposed to start with this blueprint you're supposed to start with the early foundry blueprint. That one is meant for early game, this one is not.
5h4dow (edited)
Something great about this design is it fits at the bottom of the Armageddon crater. So if you build a path to the bottom and ramps up to the sides you can just build stackers that dumps all excess raw ore over the sides of the crater and have it collect to store at the bottom. Then you can just have a couple of excavators at the bottom extract from the piles based on what resources you need most.
Calen (edited)
@5h4dow - That's awesome! Send me a screenshot on Discord sometime.

My current issue is that the ingress for the coal line is a flat conveyer not a u-shaped one. I did drop the Completed BP and that is working great, your BP's are top notch friend. Any chance of getting a picture of the back end hookups on the finished build?
Calen (edited)
@HopsterCitrine - Thanks! I'm glad you like my blueprints! So here's what happened... The Ingress transport blueprint was designed for the stage 1. However, in stage 7, the Graphite and Coal storage switch places. That's why the completed build and the ingress transport don't work perfectly together. So I created a new blueprint called, Foundry Ingress Transport - Completed Build.
Stragler76 (edited)
Loving the Blueprints, Calen. Will this and the MH be updated for Update 3? As well as farm and Food & drug? I am loving the new, smaller ones for early game, but afraid to start with these if the updated ones come in a day or two. (Don't make me try to figure out this stuff on my own!! lol) I am not sure what else changed, recipe-wise, beyond the loss of bricks. Also, have you considered adding Concrete and paper to this BP? I have made my own add-on BP to tack on the the side of this one with those two added, although I expect I will have to do it again after this is updated. Again, Best blueprints on here, Cheers.
Calen
@Stagler76 - The UF U3 build is ready now! I don't have a date for the rest yet, but I am working on them. I have concrete in a separate blueprint. I considered adding it several times to the Unified Foundry, but ultimately decided against it.
Hail
Not sure if acid makes it to the gold.
Kozrek (edited)
No, he forgot the connection to acid storages with atep 4, pls fix.
Djinsomnia
@Hail @Kozrek - The connection is there, you must have misplaced the gold blueprint as it works fine on mine. On the note of gold however between the 1st two and last 4 gold smelters one of the belts is facing the incorrect way from the settling tanks. Not a huge issue just a case of changing the direction but just in case someone else notices it. Again Thank you for all your hard work on the BP's Calen they are amazing and my game would look trash without them xD
wickys
Am I stupid? How is this ingress supposed to connect? https://imgur.com/a/CbutxAo
Calen (edited)
@Djinsomnia - Fixed! Thanks!
Calen
@wickys - It doesn't anymore. I need to update all transport blueprints, but wanted to wait until I figured out trains. But getting all of these blueprints up-to-date has taken precedence over that.
Maslygan
@Calen theres missing an aluminium scrap bucket/sorter for the recycling center bit. Looks great tho other than that so far. maybe in the future, add the Co2 > graphite and also somewhere to bin off the wastewater from gold smelting, unless thats part of one of your other blueprints and i just havent put it down in my game
LordDudel
iam keeping the old ingress/egress, so thanks for the underpass options. kinda like that the old ones are not too high. makes connecting things overpass easier.
mhcoi2025
Would you be able to add aluminum processing to this? also acid, you could put acid on the opposite side of the recycling next to the silicon, that's where I put it in mine. rerouted the sulfur to be the input for it.
LordDudel
i just realized that all the arc furnances are emitting steam low. wouldn it be good to integrate a small power plant to utilize it before reclaiming the water?
L3ft4d3adt
@calen the gold mixers are missing a acid pipe
iifetap
Is it just me or is there no direct Unified Foundry ---> Manufacturing Hub transport blueprint? I managed to connect it on my own but it just doesnt look as pretty as all of your other transport blueprints.
Yasha
Adding does not work for me. What's strange is that all the other things I've tried so far have worked. But somehow it doesn't like it here. When adding, I get the message: Failed to import the specified string.
BrickedKeyboard
Just played through U3 with the unified foundry. (1) the silicon arc smelters were missing an upgrade step or water line or steam out (2) I felt like the sand storage was about half what it needed to be, and you needed about twice as much polysilicon production (3) in most places t3 belts aren't needed but in a few spots they were including the polysilicon production, good use of t2 belts. (4) the graphite plant to recycle the waste CO2/make electrodes with coal would be nice to add to the plant (5) similarly, using cooling towers only to cool the steam isn't great, the plant can make its own water easily off of steam using the low steam thermal desalination recipe. I didn't check the math but this might provide enough brine for electrodes and salt for glass. (6) Since it has exhaust scrubbers, and because sulfur is smaller volume than acid, instead of accepting acid as input the plant can make it's own, I calculated 5 mixers. (7) the rail station should accept raw ore, and use a central bank of crushers that share inputs (kayser has one)
wickys
@iifetap yes connecting the foundry output to hub input is a mess. There's also a mismatch for instance of how many lines of copper ingots go out the foundry vs go in the hub
Calen
@Maslygan - Aluminum scrap handling fixed. You just don't get enough bang for your buck with CO2->graphite production for me to want to take up space including it in the Foundry. I'll consider added toxic slurry processing in situ, but they're just so darn bulky. @LordDudel - (thumbs up) @mhcoi2025 - Done and done. @LordDudel - Not a bad idea. @L3ft4d3adt - Fixed in previous build, but definitely fixed in the latest one too. @Yasha - I have no idea why this would be happening. Maybe try from a different browser? @BrickedKeyboard - (1) I don't think it was. Moot though since I've created a new silicon blueprint. (2) feel free to increase to tier IV storage. I don't seem to, but I don't build solar panels. Is that why you need more? (3) I like tier III belts, everything moves faster. (4) See comment to Maslygan. (5) I thought about this too, but did not want to import seawater, but that seems silly now that I type it out. I'll consider this in the future. (6) Done, but I only added 4 since the Foundry is usually not at full capacity until I'm switching to Arc Furnace II anyway. (7) Crushers take up way too much space to place them near the factories. Instead, I crush at the mines where there's a lot more room. @wickys - I made it slightly better in the latest build and include transport diagrams in the latest guide. Prefab belt blueprints are the bane of my existence. :)
CalensFanboy
Hey @Calen i created this account just for you as you can see from the nickname :) I used your blueprints a lot of times and they are excellent. They must've took your time a lot so i was wondering if you are accepting donations of some sort.
