Description
Hot pressing is a shaping process for compacting/sintering of powders or powder compacts using temperature and pressure.
The consolidation of mainly composite materials or technical ceramics usually takes place in graphite molds using temperature (resistance heating) up to 2400 °C and uniaxial pressing force up to 50 MPa in a vacuum or inert gas atmosphere.
Functions
- Hot pressing in vacuum, relative pressure
- Sintering in vacuum, relative pressure
- High flexibility in process optimization and design
- Extensive data evaluation
- Product development, prototype production, series production
- Measurement of compression path and speed
- Force- or speed-controlled processes
- Design and optimization of pressing tools/concepts
- Loading and unloading systems
Description
- Working temperature up to 2200°C
- Vacuum: 5x10-² mbar(a)
- Furnace atmosphere: Ar / N2
- Servo-hydraulic force control
- Precise, rigid press frame with low deformation, exact guidance of the press plungers
- Easy accessibility
- Resistance heating
- Double-walled, water-cooled stainless steel vacuum container
- Handling systems, especially for large-format systems
- Comprehensive user-friendly control system Siemens S7 and WinCC
Options
- Working temperature up to 2400°C
- in air max. 1400°C
