company news about The Unique Design for IKEA suppliers ---4-point bending stiffness tester

Paper and board----Determination of bending stiffness—General principles for two-point, three-point and four-point methods. Today I will take you into the world of 4-Point Bending Tester.

1. What’s the 4-Point Bending Tester?

The 4-Point Bending Tester measures the bending stiffness of corrugated board and heavy paperboard rapidly and accurately. The unique design of the pneumatic clamps permits measurements of warped and twisted samples without impairing results.it is widely used for IKEA suppliers to better control the cartoon quality

2. The Function of 4-Point Bending Tester

A: Measuring the resistance of the test piece offer to bending, in the region of elastic deformation

B: Be suitable for corrugated paper board (Flute A,B,C, E BA, BE)

C: A precise sensor measure the linear deflection caused by bending display on the screen and send to the micro-processor for calculation through the communication port.

D: Automatic zero set point of the transducer compensate various thickness of the paper board.

E: Length of paper board is adjustable from 250 to 500 mm. Make use of a stepping motor, left/right turn ball screw, the change of paper board length is much easier, the required length can be set and automatically done by the machine.
