The hits just keep coming.

Titanium with falsified documents used in Boeing and Airbus planes.

I saw this today also. We machine a bunch of titanium, some of it being customer supplied. The customer supplied stuff is typically the cheapest shit they can find. I have seen pockets of sand in the middle of 2" round bar. Small, tiny pockets, but still pockets with sand that really fuck with a wire EDM. Milling the shit...sucks. Sometimes you get the tool life you would expect from domestic material, other times you get 50% of tool life, other times you get 5% of tool life.

If the falsified shit was anything like the stuff I have experienced....the machinists defiantly knew something was up long ago.

Doesn't Boeing have an approved list of material suppliers?  Are you allowed to just buy the cheapest shit from anywhere?

I believe what is happening in this case is the material was purchased from an approved supplier. The supplier was the one who provided falsified certs.

This is not the first time this has happened, far from it. Look up Kobe Steel scandal. Apparently they were falsifying records and certs for decades. I recall another material supplier on the west coast doing the same thing maybe 10 or so years ago.

Doesn't Boeing have a crew in space right now or something?
I wonder how confident they are in the build quality of their craft.

The leaks say; NOOOOOO!!!!!!!!!!!

LOL!! They were scheduled to leave the ISS but are delayed due to various leaks.

Does not bode well when you are engulfed in flames on re-entry.

They should probably prepare themselves for that.


I have a friend out here who is a contract programmer. He was just telling me about this crappy piece of titanium he was supposed to make a part with.

Not titanium but when I worked for the fishing reel company we ended up buying hand held x-ray material scanners because overseas suppliers kept sending "certified" lead free paint on kids products. Believe it or not, ambulance chaser type law firms in Cali send people to stores regularly to buy kids products and test them for lead. If they find lead they try to mount a class action lawsuit. We had to recall hundreds of thousands of kids fishing rods because of lead paint that was supposedly lead free.

When I did DoD work EVERYTHING was x-rayed or fully certified.

I don't understand any of the failures at Boeing.

Failures of this quantity and magnitude seem like it's not accidental. It just doesn't pass the smell test.

Try Clinton/Gore China visits and Trade Bill.

If you've never had to rework a Chinese Mold or Die to make it work.

you prolly won't understand.(no offense meant)

And the shit is absolutely terrible steel. Never understood the idea of sending a $200k mold to China to be made for $100k, then get it, test it, have to put $100k more work into it, and get 1/4 the life out of it before being trashed. Been through it many times, and people were surprised when the company folded.

Walmart mentality...

You can get it built and fixed multiple times for the cost of building here...

The company I work for is still building their own molds.

Especially when it was a "Medical Mold" Facility.

They handed out Pagers to Call and notify us as the Molds Failed.

I was at My Sons Baseball game as they Paged. Failure!! Failure!! Failure!!

Every Mold had to be reworked.
