OTF-1200X-VHP4 Vacuum Pressing Furnace with 4″ Quartz Tube, 2T Digital Electric Press, and 1000ºC Max Temperature
The OTF-1200X-VHP4 is engineered for laboratory processes requiring the densification of compound materials under controlled vacuum and high-pressure conditions. It integrates a split vertical tube furnace with a vacuum-sealed 4-inch diameter quartz tube, enabling precise thermal treatment up to 1000ºC. This setup is ideal for applications demanding uniform heating and vacuum environment to minimize contamination and oxidation during pressing.
A key feature of this system is its built-in digital electric press capable of applying up to 2 metric tons of force with high accuracy (±0.003T). The press stroke is 20 mm, and pressure can be adjusted continuously from 0.1 to 2 tons with a constant pressure function. The furnace temperature is controlled by a Eurotherm 3000 Series controller supporting up to 16 programmable segments, providing precise temperature ramping and holding with ±0.1ºC accuracy.

Typische Anwendungsbereiche
This vacuum pressing furnace is suited for producing dense ceramic, composite, and advanced material samples that require precise temperature and pressure control under vacuum. It is commonly used in materials science research, battery electrode fabrication, and semiconductor material processing where contamination-free high-pressure sintering is critical.
Hinweise zur Konfiguration und zum Betrieb
The system includes one set of graphite pressing dies and supporting rods. Graphite dies are consumable and can be replaced or customized up to 1″ ID at extra cost. Water-cooled flanges require a minimum 12 L/min water flow; a recirculating water chiller is recommended to conserve water. Vacuum pumping requires an optional turbomolecular pump for high vacuum levels. A two-stage gas pressure regulator must be installed on gas cylinders to limit pressure below 3 PSI for safe operation. Optional electric presses with higher force capacities are available. The furnace is CE certified, with additional certifications available upon request.
