Graphite Machining, Inc. (GMI) of Topton, PA and Solar Manufacturing of Souderton, PA have been cooperating for the past year on the development and testing of a new graphite board material and its application for vacuum furnace hot zones. This new graphite board material has undergone extensive thermal and vacuum testing to prove its improved thermal efficiency and excellent vacuum performance compared to prior or present graphite board designs.
GMI intends to market this new graphite board under the name of HEATGUARD insulation while Solar Manufacturing will incorporate this new material into its vacuum furnace hot zones under the trade name of HEFVAC™ (High Efficiency Vacuum).
Frank C. Schoch president of GMI states “After extensive testing against our existing and competitive insulating materials, Solar Manufacturing and Graphite Machining combined our respective experience and created this new thermally efficient graphite board insulation material.”
Incorporating this new HEFVAC™ board insulation, Solar Manufacturing has now developed a proven more thermally efficient vacuum furnace hot zone design that is capable of achieving faster and better vacuum levels because of the HEFVAC™ sealed and low moisture absorption structure.
