Our recent discussions of Greenline clarinets prompted me to wonder about how they're made. Are they turned on a lathe and bored, like wooden clarinets? Or are they molded? I'd always assumed that your typical plastic clarinet was molded (though I don't have any basis for that), but these aren't typical. I can't really picture how turning them would work, since there's no longer a grain, but I know very little about working the wood.
Just curious,
Jen L.

According the Buffet they are bored.

Jen you dont need grain to turn a material. Metal lathes turn metal with no grain. Plastic items are often machined from the solid, mainly when demand is such that extremely expensive moulds are not warranted.

My knowledge of machining and casting and forging is almost exclusively with metals, but for something as accurate as a clarient bore and holes, you could cast a near net shape piece (OK, you couldn't really cast a clarinet in metal, but....), but you would have to finish machine it. Is this the case with large run horns, or do they either just sacrafice the accuracy or is the accuracy good enough straight out of the cast mould?

I don't know. But plastic Yamahas have undercut tone holes. I can't imagine them moulding those when they could be cut very quickly by a CNC machine.
On Yamaha the posts are screwed into threaded holes in the plasitic. I can't imagine these threads being moulded.
On the other hand most, if not all, other makes of student plastic instruments have posts that are moulded in. No thread.
