Paper Board Four Point Bending Stiffness Test Machine
 


Product Description
 

4-Point Bending Stiffness 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.

 

Advantages:
 

1. 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. 
 

2. Length of the test board is one of the critical factor to affect the test result, HD-A544 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 
 

3. 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-A544 increases the credibility of the test result. 
 

4. No matter the thickness of the samples, HD-A544 equipped with an intelligent detector to get the zero reference point. Test becomes more convenience. 
 

5. 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.  
   

6. Shear force (one of a uncertainty) in this test method has been overcome by applying special mechanism on the clamping plate. 

 

Features:
 

1. This 4-Point Bending Stiffness Tester is to measure the resistance of the test piece offer to bending, in the region of elastic deformation.
 

2. The 4-Point Bending Stiffness Tester is suitable for corrugated paper board (Flute A,B,C,D & E)
 

3. 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.
 

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

5. 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.
