OTF1200XVHP6 Vacuum Hot Press Furnace with 6-Inch Tube, 1100°C Max Temperature, and 20 Ton Pressing Force
The OTF1200XVHP6 is engineered for laboratory-scale preparation of dense composite materials requiring controlled vacuum or inert gas environments. This system integrates a vertical split-type tube furnace with a 6-inch diameter quartz tube and a high-capacity programmable electric press capable of exerting up to 20 tons of force. It is optimized for processes demanding precise temperature and pressure control up to 1100°C.
The furnace uses Ni-Cr-Al resistance wire heating within a single temperature zone of 300 mm length, providing uniform heating with a maximum rate of 10°C/min up to 800°C and 5°C/min from 900°C to 1100°C. The quartz tube is sealed with water-cooled flanges equipped with vacuum ports and gas inlets, enabling operation under vacuum or controlled atmospheres. The pressing assembly includes graphite pressing rods and dies designed for high purity and durability under pressures up to 100 MPa.

구성 및 작동 안내
The system includes one set of 1″ ID graphite pressing dies and graphite pressing rods. Graphite dies are consumable and fragile; ordering spare sets is recommended. Optional alumina or boron nitride pressing rods can be supplied. Water-cooled flanges require a minimum water flow of 12 L/min; use of an optional recirculating water chiller is advised to conserve water. Vacuum pumping options include a turbo pumping station for high vacuum (down to 10^-4 Torr) or mechanical pumps for moderate vacuum (10^-2 Torr). For safe gas operation, a two-stage pressure regulator must be installed to limit gas pressure below 3 PSI.
