Author: Question by justbecause: Manufacturing process?
What is the manufacturing process of plastic gears – in particular, nylon gears. I’ve read somewhere that its injection molding and in other articles i’ve read its milling/hobbing. Anyone know what is correct? Thank you in advance – much appreciated!

Both methods are used, injection molding and machining.
Mass production uses injection molding.
Specialty/ one of/ sample/ prototype/ custom, uses machining.
Once a gear prototype made by machining is accepted, a mold can be made for a injection molding machine, then mass produced.
