OTF1700X4RHP Rapid Heated Pressing Furnace with Induction Heating, Up to 1700ºC and 100 MPa Pressure
The OTF1700X4RHP is engineered for rapid consolidation of powdered materials into dense pellets using a combination of high temperature and pressure within a controlled atmosphere. This system is ideal for laboratory applications requiring precise hot pressing under vacuum or inert gas environments to prevent oxidation or contamination during processing.
This furnace integrates a 15 kW induction heating coil housed inside a stainless steel vacuum chamber, enabling rapid heating of the graphite pressing die to temperatures up to 1700ºC. The induction coil frequency ranges from 30 to 80 kHz, providing efficient and uniform heating. The pressing mechanism is an electrically driven hydraulic press inserted from the bottom of the chamber, delivering up to 5 metric tons of force, which translates to a maximum sample pressure of 100 MPa when using the included graphite dies.
Wichtigste Merkmale
- 15 kW induction heater with precise temperature control and rapid heating rates.
- Stainless steel vacuum chamber with KF-25D port, pressure gauge, and gas inlet valve for inert or vacuum atmospheres.

Typische Anwendungsbereiche
This furnace is suited for rapid hot pressing and consolidation of powdered ceramics, metals, and composite materials in research and development settings. It enables fabrication of dense pellets and components requiring controlled atmosphere and precise temperature-pressure profiles.
Hinweise zur Konfiguration und zum Betrieb
The system includes one set of high-purity isotropic graphite dies with mica spacers for height adjustment and thermal insulation. Graphite dies are consumable and fragile; additional sets can be ordered separately. Optional vacuum pumps and water chillers are required but not included. Safe operation requires a two-stage gas pressure regulator limiting gas inlet pressure below 3 psi. The furnace design was updated in December 2025 for improved exterior.
