And don't think you can't find bad molders here in the US, or moldmakers that steer your work to a certain molder, who just happens to be an in-law. The best was a molder that found a way to "lose" several parts of a mold just as it was being picked up and moved to another mold shop. "Must have fell of your truck, buddy!". Hmm.
Oh yeah: if you let the moldmaker do the mold design, be sure and get copies of all the files, even if you don't have the CAD system to open or edit the files! Don't trust 'em to back up their hard drive.

* Can't be fully certain it's intentional, given the many examples Google has for the phrase where the use of "mettle" (or "medal") is clearly a mistake.
