There is a single(?) tech unlock called "big-smelting".
When unlocked, a long list or recipes take inputs in 1's or 10's and spit out lots in 100's or 1000's depending on recipe.
That seems to be the core of the mod if anyone wanted an idea.
Example LUA:
{
type = "recipe",
name = "mi-iron-plate",
category = "advanced-crafting",
enabled = true,
ingredients = {{"iron-ore", 1}},
result = "iron-plate",
result_count = 1000
},
