4 Point Bending Test Machine


 

Product Description:

4 point bending test machine is testing the paper stiffness instead of other methods such as 4 point and 3 point bending. 



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, 4 point bending test machine 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 4 point bending test machine increases the credibility of the test result. 
 

4. No matter the thickness of the samples, 4 point bending test machine 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.
