Is 333511 the right code for an industrial mold maker?

Yes, if you build molds for injection molding, die casting or other forming processes. Stamping dies, jigs and fixtures belong in 333514. If your main revenue is molding parts rather than building molds, use 326199 or the relevant casting code instead. If two codes seem to fit, the activity that produces the most revenue decides, and lenders will expect that same code everywhere.
