How are bicycle pedals crank arms produced?

WRT metal cranks, there's really no difference in production between a metal crank and a comparable tool.

They can be cast or forged. Some have a hollow core to reduce weight.

carbon fiber ones are trickier. Layers are laid up in molds, incl threaded inserts for pedals. Resin is injected(unless the cloth is pre-preg) then the whole thing is cured in an oven or autoclave.
