This is 4 smelters with the input and output going towards the right.

This is part of a compete package of factory parts. Quickly you can layout a total and complex factory It has the following parts. For the belts and lifts, I used Mark 3 for all of this, you can quickly upgrade or downgrade as you need.

• 1 Foundation Plain wall part. It has no roof as it can be used as filler as needed
• 1 Foundation Factory Corner. Rotate until the cut-in is inside
• 1 Foundation Factory Door with stairs already set to go to the upper floor
• 3 Constructors with the input and output going to the right
• 3 Constructors with the input and output going to the Left
• 1 Constructors with the input and output going to the right
• 1 Constructors with the input and output going to the Left
• 4 Smelters with input and output going to the right
• 4 Smelters with input and output going to the left
• 4 Foundries with input and output going to the right
• 1 Assembler with input and output going to the right
• 1 Assembler with input and output going to the left
• 1 Manufacture with input and output going to the right

This gives you the flexibility to string the items together, wire the modules together, bridge the modules with belts.

If you would like a second floor, you can still use the blueprints, just go and remove the concrete pillars that are in front of the base half foundation.
