Description
Equipment Overview
This Graphite Furnace Systems vacuum furnace is a heavy-duty, graphite-insulated batch processing system built for ultra-high temperature performance. The interior chamber contains upper and lower graphite panel arrays, vertically suspended heating rods, and precision insulation tilework. Ideal for thermal treatment of composite tooling, carbon fiber, ceramics, or hard metals, the furnace supports consistent temperature distribution and may operate in vacuum or inert gas configurations.
