Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

Main testing screw screw, screw torsion testing machine products such as screws, screw torque test and broken torque value, can also be used for metal materials and manufactured goods torsion mechanics performance test at room temperature, can also be used for materials and finished goods to reverse damage performance test, etc.

Static torque test.

Control mode 1: torsion Angle test of fixed torque, torque - time curve, torque - twist Angle curve, etc.

Control mode 2: torque test for fixed twist Angle, torque - time curve, torque - twist Angle curve, etc.

Output test report.

Automatic display: in the test process, real-time display test force, peak, test state;

Automatic correspondence: in the experimental process, the Angle and torque automatically correspond;

Automatic operation: input test parameters to complete the test process automatically;

Automatic storage: experimental data and curves are automatically stored in the computer;

Easy to query: click the query button, can query the multi-group experiment data that has been done;

Easy to operate: Chinese menu operation, intuitive and clear;

Dynamic curve: the dynamic curve can be displayed during the test.

Breaking judgment: after the sample is broken, the machine will stop automatically.

Process realization: the test process, measurement, display and analysis are completed by microcomputer;

Batch test: the sample of the same parameters can be completed after one setting.

Curve traversal: after the test is completed, the curve can be reanalyzed.

Test report: form a report and print and store it;
