Laboratory calender GK 300 L: Ultimate calender for laboratory processes – covering battery, hydrogen fuel cell and converting applications

The indispensable basis for your innovations.

Our laboratory device for comprehensive testing options – modular, flexible, and precisely tailored to your processes.

The laboratory calender GK 300 L is truly universally applicable. As it is designed as a “plug and play” system, it only requires a power connection and can be used wherever tests and experiments are carried out with a wide range of materials such as like plain and coated foils, powders, slurries, granules, or sheets. As such it is the laboratory equipment of choice used in research projects of institutes and universities, as well as in research and development departments of well-known companies from the automotive sector, plastics and chemical industries and for the development of hydrogen fuel cell production equipment. As calender for the battery industry, it enables the mapping of relevant scalable laboratory processes in the battery sector.

Compressing, embossing, laminating – our laboratory calender can be configured exactly according to your demands and your experimental set up.

Wherever processes are tested on a laboratory scale, you can rely on the GK 300 L.

For mapping relevant scalable laboratory processes in the battery field.

For testing your manufacturing processes for hydrogen fuel cell components.

For your product developments and in-depth material tests in the converting sector.

Our basis laboratory calender – GK 300 L

With the laboratory calender GK 300 L, the calender unit can be flexibly set up vertically or horizontally on the trolley thanks to pre-prepared holes and connections. An infeed table for sheets and web, a hopper for powder feeding as well as guide rolls that allow for a flexible web path are included. The gap adjustment reaches an accuracy of +/-1µm, and a gap force of up to 15 tons can be mapped. The rollers of 300mm width rotate at a speed of up to 5m/min.

Gap adjustment
  • Gap adjustment via ratched
  • Special wedge system, also adjustable under full pressure
  • Independent gap adjustment (left/right)
Measurement systems
  • Measurement of the roller position
  • High precision measurement sensors
  • Independent gap measurement (left/right)
  • Accuracy of +/-1µm
