sst / shear stiffness testing system

  • compact laboratory equipment that allows determination of shear stiffness in the plane of the cardboard sheet, interacting with transverse shear,
  • the test consists of the static measurement of the stiffness of the corrugated board, by applying a pair of forces, twisting the cross-section of corrugated cardboard with dimensions 100×100 mm,
  • SST is characterized by a very high sensitivity to crushing the corrugated board section in processes such as die-cutting, laminating, etc. – by performing a reference test (before the process) and control (after the process) it is possible to very accurately assess how a given process affects the material and by how much the load capacity of the packaging is lowered,
  • advanced algorithms and precise measurement system allow to obtain accurate and reliable results,
  • small dimensions of the device and the lack of the need to use compressed air allow SST to be set up anywhere in the production hall in order to control the crush of cardboard,
  • main parameters:
    • device dimensions: 250 x 160 x 240 mm,
    • device weight: 5 kg,
    • sample dimensions: 100 x 100 mm,
    • accuracy of force measurement: < 0.03 gr,
    • accuracy of displacement measurement: < 0.01 mm,
    • power voltage: 240V,
    • communication: USB.
