Proto Space is an: Excellent machine shop capable of just about anything you would need including specialty welded over lay parts and HVOF coated parts. Both conventional and CNC machine capabilities are awsome and they can provide quick turn services. We use them year around and they allow us to maintain competitive prices on many machined parts that start from raw materials or castings as well machining old parts to re-claim them for another service cycle!
