Industry Application
Vacuum Furnaces for Graphite, Hard Metals and Advanced Ceramics
Purification, sintering and hot-press equipment to 3,000 °C for battery anode graphite, tungsten carbide, technical ceramics and sputtering targets.
Advanced materials are defined by what is not in them. A few hundred parts per million of iron in battery anode graphite, or a percent of residual porosity in a carbide insert, is the difference between a premium product and a commodity one.
Our vacuum range covers the three processes that remove those defects: high-temperature purification that volatilises metallic impurities out of graphite, vacuum sintering that eliminates trapped-gas porosity, and hot pressing that densifies materials which will not sinter under pressure alone.
What This Industry Has to Solve
The three problems that decide whether an installation in this industry pays for itself or becomes a maintenance liability.
01
Purity without wet chemistry
Thermal purification at 2,800–3,000 °C reaches very high carbon purity without the acid or chlorine handling, effluent treatment and permitting a wet route requires.
02
Uniformity across a large charge
±5 °C across the working volume means the parts at the edge of the load meet the same specification as the parts at the centre — the usual failure point when a process is scaled up from a laboratory furnace.
03
Batch documentation for qualification
Full recipe and process logging per batch gives the process record that battery, aerospace and semiconductor customers require before qualifying a supplier.
