Torsion test machines are a great way to measure the torsional strength of metal, non-metal and composite materials. With the right torsion test machine, You can accurately assess the torque and twist resistance of different materials with precision and confidence. The Wewon’s torque test machine applies a rotating force to the material at a known rate of speed, allowing you to measure the resulting amount of torque needed to achieve a certain degree of twist. It uses one stationary base and one rotating base, along with sensors positioned between them in order to measure torsional properties like its maximum twisting torque, angular twist resistance and geometric properties.

Torsion Testing Machine Working Principle : Torsion test machine is suitable for determining the ability of metal wires with a diameter (or characteristic size) of 1-10mm to withstand plastic deformation in one-way or two-way torsion and to display defects on the surface and inside of the wire. It clamps both ends of the sample, one end is fixed, and the other end is continuously rotated 360° or 180° reciprocatingly twisted until the sample is twisted or the paint film of the enameled wire falls off, exposing the conductor, and the number of torsion resistance is recorded. The machine can be selected for single forward rotation or single reverse rotation.

Selecting the appropriate torque test apparatus will depend on the type of material you’re testing. For metal and non-metal materials, clamps should be used to secure the sample in place, while composite materials may require extra fixtures. Make sure these torsion test fixtures are compatible with your torsion tester machine and its sensors before running any tests. It is also important that they’re strong enough to hold firmly different sized samples within a tight tolerance range.

Flexibility Test Machine for Wire and Cables Manufacturers
Using the latest microcomputer controller, the circuit has been specially optimized and designed according to the working characteristics of the system, with strong anti-interference performance and stable and reliable operation.Equipment Features:
Wewon’s torsion testing equipment has a twist-off stop function. The display part adopts a large-area LCD liquid crystal display, with full English prompts.
The control program is designed according to the principle of humanization, which is easy to operate, clear in display and accurate in results.
The controller responds to the parameters and operation instructions set by the user, controls the operation of the frequency converter, thereby controls the operation of the motor, and realizes the required test function.
1. The output shaft can be controlled to run at a specified speed by the controller.
2. It can control the forward or reverse rotation of the output shaft to realize the loading on the test piece.
3. It can record the number of times the material is twisted before breaking, with an accuracy of 1 revolution.
4. The number of twists can be set, and the forward and reverse directions can be set arbitrarily.
Torsion testing machine uses an AC servo motor to drive the planetary gearbox to run, and drives the moving chuck to make the sample rotate positively and negatively. The equipment has a high degree of automation and stable performance.
Wrapping machine manufactured by Wewon Environmental Chambers Co., Ltd. is controlled by touch screen, PLC and stepping motor, and the twisting angle, frequency and speed can be set directly.

For accurate results, it’s important to set your torsion test machine to appropriate torque settings. Different materials require different torque values based on properties such as modulus of elasticity and yield strength. Once the torque setting is in place, You need to ensure that the same exact steps are executed each time test apps are run. To increase reproducibility, ensure that the rotational speed and load are maintained throughout the testing process. This allows you to get more consistent results each time which will help strengthen your conclusions.

The specimen must be appropriately positioned and secured onto the torsion test machine so it cannot move around. Once properly secured, the distance between the jointed surfaces should be such that torque is applied close to its center of gravity. It’s important to make sure that the sample remains free of contamination during testing. This could cause an error in readings, leading to incorrect results or faulty conclusions.
