Automatic Bursting Strength Tester

These Automatic Bursting Strength Tester is a new type testing apparatus to test the bursting strength of corrugated boards, which is designed to be in accordance with related national standards and on the principle of modern mechanical design concept and design criterion of human-machine engineering.
QD-3005B Bursting Strength Tester has abundant functions, such as, parameter testing, parametric transformation, parameter adjusting, parameter memory and parameter print. All are in accordance with related national standards. Corrugated Board Bursting Strength Tester Principle:
A test piece placed over a circular elastic diaphragm, it is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, and bulged the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
