Graphite Machining Inc.’s recent innovation, HEATGUARD Insulation, is the latest improvement in vacuum furnace insulation.

HEATGUARD Insulation is Carbon Bonded Carbon Fiber (CBCF). By locking the carbon fibers in place, using our proprietary forming process, HEATGUARD Insulation is much tougher and more dent resistant than other board insulation. Moisture resistant, rugged and durable - means our insulation is with you for the long haul.

GMI can provide HEATGUARD Insulation as machined components or stock boards. Many shipments can be made from our stock supplies or within a couple of days. Reducing downtime and helping you return to peek performance faster.
