Crease and Stiffness Tester

Specifications

MANUFACTURED ONLY BY IDM IN AUSTRALIA, model C0039 Crease and Stiffness Tester is a dual purpose instrument measuring crease or board stiffness in a quick and easy process.  It features a digital display with a range of 0-1000gf, and an accuracy of 0.1% F.S.

In modern high-speed packaging machines it is very important to have the creases in boards correct and uniform.  The value of crease stiffness is technically important in the folding of carton blanks during their erection and closure.  Whether this is by hand or by mechanical means.  The crease recovery (spring back) can result in forces, which distort the erected carton or cause stresses to be applied to closures, which reduce their effectiveness. 

Crease recovery is determined by the decrease in resistance offered by creased board after it is folded 90° at the crease measuring the recovery force after 15 seconds.  Board Stiffness is determined by bending a 50mm length of board through a 15° angle.

IDM’s precision cutter model C0016 is designed to assist in the easy and accurate cutting of sample specimens for botcrease stiffness and bending stiffness testing.

SAMPLES: • Crease stiffness testing 38 x 36mm • Board samples 70 x 38mm

Standards: BS 6965; BS 3748; ISO 2493: 1992

CST Software

The IDM Crease and stiffness tester can be purchased with standard RS232 and software to automatically capture the output of results to a PC where stiffness/crease ratios can be calculated, test results saved, and test reports created and printed.

This makes the CST even more easy to use with accurate precision results.
