Production Buildings: Drills, Furnaces, Assemblers

Factorio's production buildings like Drills, Furnaces, and Assemblers drive your factory. Learn crafting speeds and module slots for efficient automation.

These are the machines that do the work. Mining Drills extract resources. Furnaces smelt ores into plates. Assembler Machines craft components and items. Chemical Plants handle fluid recipes. Oil Refineries process crude oil.

Each building has different crafting speeds, power consumption, and module slots. Upgrading to higher-tier versions (e.g., Assembler Machine 3) significantly boosts efficiency.
