The flexural strength represents the highest stress experienced within the material at its moment of yield. 3 Points 4 Point Bending Strength Testing is most frequently employed, in which a specimen having either a circular or rectangular cross-section is bent until fracture or yielding using a three point flexural test technique. The test method for conducting the test usually involves a specified test fixture on a universal testing machine. The sample is placed on two supporting pins a set distance apart. Details of the test preparation, conditioning, and conduct affect the test results.

Main Features of 3 Point 4 Point Bending Strength Testing Machine

Graph scale automatic optimization allows best measurement and can implement graphics dynamic switching by the test.

Whole facility structure is made of baking varnish aluminum profile, and inner part is applied the high-accuracy, low-resistance and zero clearance of dual-ball screw and oriented pole,  through which highly improve the loading efficience and structure rigidity.

Apply brand computer as the main control system, computer control with software, back to origin automatically after the test, and can store data automatically or by manual operation 

Data transmission: RS232, and displacement resolution: 0.001mm

Use famous brand Panasonic servo motor, which ensure high efficiency, steady transmission and low noise.
