Sintering furnace

Sintering is the process of compacting and forming a solid mass of material by heat and/or pressure without melting it to the point of liquefaction.

Small production scale

Medium production scale

Large production scale

Key Features:

  • High accuracy chamber
  • Easy access to all components for repair and maintenance
  • Temperature up to 1,800°C
  • Sintering under pressure / vacuum
  • Integration of sensors in oven body
  • Acceptances including shrinkage body and TC measurement
  • Highest temperature uniformity (as low as +/- 2°C in usable area)
  • Very user friendly operating interface / software
  • Double (PLC and PC) operation for high uptime
  • Fully automated solutions available

Key Features:

  • The electrically heated elevating hearth furnace with max 6 product stacks serves for de-binding and sintering of LTCC ceramics with thermal after-burning and dosage of gas preheated by SiC heating rods
  • 28 heating groups are implemented. The installed heating power of the SiC rods is 300 kW (at 1000°C and a surface exposure of 10 W/cm2).
  • The preheating of air or nitrogen is polished by gas dosing through the SiC heating rods. The entering fresh air or nitrogen are pre-heated corresponding to the programmed kiln temperature
  • The kiln is equipped with a spindle lifting device and a hearth. The charged hearth is moved into and out of the kiln by the spindle lifting device
  • The hearth boogie is fixed at the spindle lifting device. Charging and discharging is carried out at the front side of the kiln

Key Features:

  • The smallest usable volume is about 75 liters. The kiln is heated by two-leg heating elements made of Kanthal Super 1700-9/18
  • The total installed heating power is above 59.0 kW and is dimensioned for a temperature of the kiln chamber up to 1600°C
  • Temperature deviation across the usable oven chamber to about +/- 2.5K
  • Accuracy of +/-1K during heating in a temperature interval above 300°C
  • The hearth is pivot-mounted at the lower closing plate of the kiln and is driven by an electric motor outside the kiln
  • The rotary hearth can be moved into and out of the kiln by a lifting platform with spindle. The gas feeding of the kiln device is provided by mass flow controllers for the following gases: oxygen, nitrogen, air
