Thermoforming of organ sheets

Mould carrier for injection moulding
Bolt-on injection: Back injection of semi-finished products

The multiprocess capability in conjunction with the compact design as a short-stroke press opens up completely new possibilities in production.

Hydraulics: High-speed control loop and maximum power

Our short-stroke models allow high-speed material transfer with full control of parallelism and maximum press force:

  • Pressing force 26,000 kN (hydraulic pressing force up to 50,000 kN possible)
  • Closing speed 800 mm/s with a moving mass of over 60 tonnes
  • Extremely fast control loop of less than 100 µs
  • Pressure build-up in under a second
  • Eccentric load up to 21,000 kN (kilonewton)
  • Full speed material transfer with full control of parallelism
  • Automatic tool changing systems

The values listed are examples of short-stroke presses from Langzauner Perfect’s mechanical engineering division.When planning and executing new composite presses, we are guided by the values you need to achieve for your process flows.

Short control loop for highly reactive process

A powerful CPU enables highly reactive parallelism control, which directly influences the material properties during the pressing process. The exceptional reaction times are achieved thanks to the incomparably short control loop of the Langzauner short-stroke presses.

Innovative infrared ovens and transfer axes

30 infrared heating fields can be individually controlled and regulated with the press control. With the innovative infrared ovens, energy consumption is greatly reduced. At the same time, the heating fields can be adjusted directly to the material thickness.

Exemplary performance data of an LZ Perfect system:

  • Infrared heating for high temperatures over 500°C
  • 585 kW Peak heating power
  • 30 freely programmable control zones
  • 18 pyrometers (heat measurement) and 12 thermocouples
  • Each heating element can be regulated between 0 and 100% and assigned to a control zone
  • Transfer time from the oven to the position in the press is a few seconds
  • Line Scan Cameras detect irregularities
  • Combination of heating and cooling plates possible

Performance of IR heating fields as well as transfer times are defined in consultation with our customers.– The process requirements always set the pace for the performance of the customised short-stroke press from Langzauner Perfect in Upper Austria.
