Stainless Foundry & Engineering (SF&E) has “engineering” in the name because we aren’t just a particularly focused alloy foundry, we produce over 250 different ferrous & non-ferrous alloys. Metallurgy has always been a strong focus that enables us to create solutions for our customers. In continuation of our 75-year anniversary celebration, Mike Porfilio, Director of Quality, provided the following insights into how SF&E has been able to offer expertise and capabilities over the years that enable us to deliver both high-quality, high-tech castings as well as commercial grade castings to our customers.
Looking back, how would you summarize where SF&E was, and where it is now in terms of quality and engineering?
Porfilio: In 75 years, there have been so many changes in the technology of casting production. I remember running chemical analysis samples on an x-ray spectrometer and then pulling out the corresponding graphs to verify counts and make furnace additions. Now, we use solid state equipment which at times runs completely with computer chips. Hardness testing devices still resemble those of the past for the most part, but Leeb rebound style tests are always evolving. Dimensional inspection used to require long rulers (scales), which has been replaced with computerized coordinate measuring machines (CMM), which allow us to scan parts and collect hundreds of millions of data points of measurements. Where will technology take us next?
