Vacuum Furnaces
High-strength graphite hot zones, fixtures and insulation for vacuum heat treatment and sintering.
Graphite solutions for Vacuum Furnaces
Vacuum and controlled-atmosphere furnaces demand graphite hot zone components that maintain dimensional stability and mechanical integrity through thousands of thermal cycles. Every failed component means unplanned downtime — and downtime in a vacuum furnace operation is measured not just in repair cost but in scrapped loads, customer penalties, and recommission runs.
Expo Advanced Materials supplies precision graphite hot zone components — heating elements, radiation shields, hearth rails, fixtures, and insulation boards — machined from TOYO TANSO premium isostatic grades with full material traceability, dimensional inspection certificates, and ISO 9001:2015 quality documentation on every shipment.
