Our torsion testing machines are designed and developed for conducting torsion and twist on various metal wires, tubes and sheet materials. The torque is measured by the pendulum dynamometer system. The torque can be adjusted by adding weight to the machine. Torque can also be applied to specimen by geared motor through gear box. Auto graphic recorder gives the relation between torque and Angle of twist. Our torsion testing machine offers accuracy indication of 1% of the torque.

We provide fatigue testing machines which is used to test the fatigue strength of materials and to draw S-N diagram by research institutes, laboratories, material manufacturers and various industries. Fatigue testing machine is a rotating beam type machine in which load is applied in reversed bending fashion. The standard 8 mm dia specimen is held in special holders at its ends and loaded such that is experiences a uniform bending moment. The specimen is rotated at 4200 rpm by a motor. A complete cycle of reversed stresses in all fibers of the specimen is produced during each revolution. The bending moment is applied with a lever system and can be easily changed by moving a weight over the lever. Total number of revolutions at which the specimen fails is recorded by a Digital counter. An interlocking system puts off the motor at specimen failure. Our machine complies with the requirements of IS 5075-1969 Light weight, compact size, simple design. Some of the salient features of our model are as follows:

• Simple lever system of changing load
• Accurately calibrated as per IS 5075 Calibration in Nm available on request
