Vacuum Furnace Systems (VFS) Corp., Souderton, Pa., sold an external gas quench vacuum furnace to the General Motors (GM) Powertrain Group for a federal government-sponsored Advanced Technology Program (ATP) to reduce the time required to produce tooling. GM has partnered with Extrude Hone's ProMetal division since 1996 on this development project. The VFS furnace will be used for sintering and infiltrating prototype tools generated from Extrude Hone's 3-D Metal Printing rapid manufacturing process.
