Critique: logo design for an engineering company that makes machinery

I'm designing a logo for a new company that will build plastic manufacturing machinery - a fairly small-sized low-tech industry where stability, solid engineering, and even country of manufacturer is of elevated importance.

The logo will go on a range of sizes: from small scale, like business cards, to logos imprinted on the machinery, to digital, to a sign on a building.

Features in order of importance:
