    Impossible piece from the 70s?

    I have recently started studying injection molding.

    The other day I came across a keyboard switch by IBM manufactured in the 70s early 80s.

    How is it possible to make such a complicated housing?! 90 degree shaft, with also 90 degree cylinders. and no visible marks that I can see.

    Maybe injection molding finished with some CNC? a la car engines?
