My start up uses Able to electropolish and passivate some of our medical devices. They do high quality work with very short lead times. The results have been very consistent in terms of quality. Overall we were quite satisfied.



We use Able to electropolish and passivate some of our surgical instruments. They were able to work with our other suppliers and coordinated drop shipments so that we would get our instruments microfinished in time. Their customer service is very helpful.
