Coil Fabrication Tooling The Fermi mandrel design is being adapted to our winding and curing tooling. The mandrel blocks have been redrawn and converted metric & ISO. Price enquiry to launch this week. MB (Jeumont) curing moulds will be used for curing the binder Spacers, oil circuits connections, coil handling tools to designMay 13, 2011 Collaboration meetingM.
