Touch Screen Type Paper Board Bending Stiffness Tester for
Corrugated Paper Board
Product Files:
Four-point bending means that the sample is placed on two force
points at a certain distance (the lower part of the four-point
bending jig). There are two points above the stress point (the
upper part of the four-point bending jig). The pressure is applied
to the sample. There are four points above and below the force
point and force point respectively. This process is called
four-point bending test.

Product features
- This tester is to measure the resistance of the test piece offer to
bending, in the region of elastic deformation.
- The tester is suitable for corrugated paper board (Flute A,B,C,D
& E)
- 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.
- Automatic zero set point of the transducer compensate various
thickness of the paper board.
- Length of paper board is adjustable from 50 to 300 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.
Product advantages:
- Since we are using pneumatic clamping plate to fix the test board,
small warp, twist or curl of the board is no longer a problem in
the test. This is also the reason to choose 4-point bending method
to test the paper stiffness instead of other methods such as 2
point and 3 point bending.
- Length of the test board is one of the critical factor to affect
the test result, HD-A546 give you an automatic solution. Operator
use one button to widen or shorten the opening gap between the
clamping plate, when your designated width approach, data can
automatically write into the computer for calculation, accuracy up
to 0.1mm
- Use non contact device to measure the deflection of the paper
board, this can eliminate any un-expected loading onto the paper
board such as spring load or weight of the measuring probe. The new
feature of HD-A546 increases the credibility of the test result.
- No matter the thickness of the samples, HD-A546 equipped with an
intelligent detector to get the zero reference point. Test becomes
more convenience.
- The test report prints out use conventional office printer. Thermal
paper no longer use. Text and graphic printed on the thermal paper
can not last long, it will fade out when time pass. Therefore use
common typing paper let the file keep much longer.
- Shear force (one of a uncertainty) in this test method has been
overcome by applying special mechanism on the clamping plate.
