Korutest (The Chalmers DST)

The Chalmers DST (Dynamic Stiffness Tester) presents corrugated board manufacturers and users with a very powerful, innovative new tool to measure the potential performance of their corrugated board.

The DST measures the MD Torsional Stiffness (Shear Stiffness) of corrugated board. This test is very sensitive to the overall performance of the corrugated board especially the fluted medium.

MD Torsional Stiffness measures how well the corrugated board has been made, how much damage is received during the printing and converting process and how well it will protect its contents in real world service environments.

The major upside is the establishment of consistent quality product that will allow the down weighting of components.
The test is quick and easy to perform and will lead to other savings from the abandonment of redundant QC tests like thickness, flat crush, ECT and BCT.

The Chalmers DST test is quick, and with only one button to press is easy to perform – right next to the corrugator or printer. The test result can be used immediately to make cost saving adjustments to the machine.

Over 30 companies around the world – many just like yours – have implemented the Chalmers DST as their main quality assurance device. Many are making huge savings and keeping their customers happy at the same time.
