Most of the time I'll let stuff slide, but...when it's the name of a person...I gotta pipe up.
 
cool clip but so much metal gone to waste. I think casting is much more economical and same quality if you use the right alloy no :dontknow:

No.
Casting will never be as strong as machined. There's too much "space" (technical term: voids) in castings, and that's where their weakness is.

Injection-molded metals are coming of age. Expect to see some engine blocks and other automotive parts using that technology in the near future.

We use injection-moled metal for one of the parts on my first invention. It's amazing. Cost-effective like casting, but much, much stronger with almost no 'voids'. It looks and feels like plastic, but it really is aluminum. :)
Strength-wise, I'd put it right in between cast and machined.

That waste is nothing.

There was one program I worked on where we took a 2000+ pound forging and when we were done machining it, it only weighed about 113 pounds if I remember right.

And to be truthful, it's not waste. It's all recylced and used again.

And Kevan's comments are correct also. There are some new casting methods that greatly reduce the porosity of the castings where they are considerably stronger than the old sand cast methods.
 
I think it's amazing that man has created such machines. The precision of the computer sure has made things easier to do.
 
Very Cooooool!
 
I watched the whole process...couldn't tear myself away despite the techno audio effects.....

What blew me away was the incredibe articulation of the jig. That thing is cranking every which way....Such mind blowing precision.

Thanks Denise and Jerry.....
