Jim Found this one, and it is a GEM! A video about a plastic ball valve. Really? This is a marvel of engineering? Ummm… actually… yes. Jim and I both think so, and since it’s on the internet it must be true.
This is a great 15 minute video with some wry humor thrown in that explains how it is made, and also dissects it to see how it works. This video contains a ton of info pertinent to a CIM class as well, as it talks about material properties, manufacturing processes, and design for manufacturing.
It also answers the age old question…. “How did they get the ball in there in the first place?”. Thanks Old Tony!
