Thirteen vacuum furnace techs recently graduated from the first series of Ipsen-U seminars in Hermosillo, Mexico. Representatives from Honeywell Chihuahua, two divisions of Honeywell Mexicali, Goodrich and ESCO Corp took advantage of the seminar to expand their knowledge of vacuum thermal processing equipment.  Presented by Jim Grann, the seminar demonstrated proper procedures for operating and maintaining vacuum furnace equipment, answered real-life operation and maintenance questions and taught how to improve energy efficiency and product consistency.
