How much did they increase the price, per year?

In those cases, I believe we were doing five-year contracts. I don't think TransDigm would sign up for the full five-year fixed price that we were trying to do, but it was probably around a 3% to 4% increase. They would negotiate that into the contract. At the end of the five years, when negotiating the next big contract with Boeing and others, they'd probably raise it by 7% or 8%.

How are they so profitable?

Another interesting aspect of extruding parts is the setup times. Switching to a new die run for a different shape part could take six to 12 hours. Then you'd have to tweak the shape and finish to make it perfect, run it for two hours, and be done due to the low volume in aerospace. A typical extrusion house doesn't want that kind of work; they prefer to set up a machine and run it for hours on end. We had proprietary material approved by Boeing, so when Collins, Safran, and others needed parts, it was easy to come to us as everything was pre-approved.
