Participants Have Said

“Simpson has done a fantastic job in disseminating relevant information that is both well-grounded and pragmatic. The concept of including fundamental theory with equipment maintenance and engineering troubleshooting was refreshing. A first-class presentation by a first-class company.” – Michael Gradle, Senior Metallurgist, Federal-Mogul Corporation, St. Louis, MO

“The Simpson Green Sand Preparation and Control class was time well spent. The program was specifically designed to show the interdependent relationship between maintenance, production and quality departments for achieving quality castings. As a maintenance manager, I gained a better understanding of what defines “good sand”, and the effects of “hot sand”.

"The basic operation and maintenance sections for the mullers was very appropriate. I had not worked with Multi-Mulls before, and this session gave me what I needed to know. The entire class was very well organized, and your hospitality was exceptional. After years of working with the folks in Aurora by phone, it was a pleasure to meet the sales, service, and engineering people who have been so helpful. Thanks for this opportunity and a job well done.” – Tom Zarnke, P.E., Maintenance Manager, Versa Iron and Machine, St. Paul, MN

“We need to get the best from our green sand preparation equipment; knowledge and experience are key elements to accomplishing this goal and this is what you get from the Simpson course. It should be a must on your training list.” – Gabriel Trujillo, Engineering Manager, Productora de Hierro Maleable, Guadalajara, Mexico
