The Hanatek CBT1 crease and stiffness tester is a low-cost manual instrument for testing board stiffness and crease resistance, the sample is clamped into the test jaws and the sample is rotated manually. The instrument displays the force measurement in grams and unlike other similar instruments on the market, it automatically calculates the crease to board stiffness ratio. If multiple tests are conducted, batch statistics are displayed. These can be printed for documented traceability.
For improved ease of use, a fully automated carton force analyser (CFA) should be considered, the instrument clamps the sample in electronically operated jaws and rotates the sample automatically at a pre-determined speed with pre-set dwell times.
The use of these operator-independent test methods vastly improves the repeatability of the results. The CFA also graphically displays the developing forces which gives added information on the physical changes that take place during bending.
