Wayne Gayford DePuy Synthes
US Navy Veteran who used the GI Bill to go to college for Material Science. After graduating college in Buffalo, NY in 1986, I joined Gray Syracuse in Chittenango NY as a junior engineer in their foundry lab running an optical emission spectrometer and adjusting metal chemistries. I worked for 10 years at Gray-Syracuse Inc., holding positions as Development Engineer, Sr Process Engineer and Second Shift Plant Manager. In 1996, the AMT foundry in Sharon Springs NY was my next short stop as a process Engineer. After this I joined Howmet Dover Castings in Dover NJ as a non-traditional casting process engineer, gaining high volume casting experience, Area engineer/ Process owner in shell, wax, casting, metal finishing. During this time frame, I acted as a Technology Exchange Engineer between many of the Howmet owned sites in the States and France. This involved

process improvement, product development, new equipment in loading as well as mentoring many engineers. Leaving Howmet in 2002, I ventured south to Miami, Fl accepting a job as Process Engineering leader for the next 2 years. After Sermatech closed, I joined Rolls Royce in 2004 as their Casting Subject Matter Expert and as a Supplier Development Engineer. I spent the next 7 years traveling the world looking after the casting supply chain at foundries making their Aero Engine components. From 2012 to date, I joined DePuy Orthopedics as their Foundry Process owner / Engineering Team Lead. This is my first extended foray into medical device castings. I have spent the last 7 plus years upgrading the equipment, reducing their scrap and helping develop a great team of young engineers and project managers.
