Engineered Testing Equipment
Torsion Spring Testing Machine, Built to Your Torque and Winding Range
A torsion spring tester sized to your spring’s torque range and winding angle, with automatic torque capture and pass/fail evaluation built in — not read off a dial by hand.
What It Does
Measuring Torque Through Rotation, Not Straight-Line Load
A torsion spring resists twisting rather than compressing or stretching, so testing it means measuring torque as the spring winds through a set angle — a different mechanism from a standard UTM or compression/tension spring tester. Our torsion testers wind the spring through your specified angle while capturing torque at each point, giving you the full torque-vs-angle curve rather than just a single peak reading.
- Torque measured continuously through the winding cycle, not just at one point
- Handles both clockwise and counter-clockwise winding configurations
- Automatic torque capture — no manual dial reading under rotation
Matched to Your Spring
Torque Range and Winding Angle Set Up Around Your Spring
Torsion springs vary in wire diameter, arm length, and expected torque range just as much as compression or tension springs do — and the winding angle you need to test through depends entirely on how the spring is actually used in your application. We size the torque sensor and mounting fixtures to your spring’s geometry and configure the winding range to match your real operating angle, rather than a fixed default.
- Torque sensor range matched to your spring’s expected force
- Mounting arms configured for your spring’s leg/arm geometry
- Winding angle range set to your actual application requirement
Included as Standard, Not an Add-On
Every Torsion Tester We Build Includes Automated Torque Capture
Manually testing a torsion spring means watching a dial while winding it by hand — awkward to do accurately and hard to repeat consistently between operators. Every torsion tester we build ships with software that captures torque continuously through the winding cycle, plots the full torque-vs-angle curve, and evaluates the result against your tolerance automatically.
Live Testing
- Real-time torque-vs-angle graphing while the spring winds
- Automatic pass/fail evaluation against your torque tolerance
- Repeatable winding cycles for durability/fatigue testing
Records & Reporting
- Digital test records replace handwritten log sheets
- Exportable torque-angle curves for QC review or customer documentation
- Consistent pass/fail logic across every operator and every shift

Note: Torque range, winding angle, and fixture geometry are worked out from your spring specification — share your part drawing or a sample and we’ll recommend the right configuration.
From Your Spring Spec to a Working Machine
Requirement Discussion: You share your spring’s torque range, winding angle, and arm/leg geometry.
Configuration: We size the torque sensor and mounting fixtures to match, and set up tolerance bands and report format for your process.
Build & Calibration: The machine is built and calibrated before delivery.
Installation & Handover: Setup at your site, operator walkthrough, and confirmation that torque capture is working as expected.
Ongoing Support: Calibration and servicing available after delivery.

Frequently Asked Questions
What torque range can the machine handle? +
The torque sensor is sized to your spring’s expected force — share your spring specs and we’ll confirm the right capacity.
Can it test both clockwise and counter-clockwise winding? +
Yes — mounting configuration is set up for the winding direction(s) your spring requires.
Does it capture the full torque-vs-angle curve, or just a peak reading? +
The full curve — torque is measured continuously as the spring winds through the specified angle, not just at one point.
Can it run repeated winding cycles for durability testing? +
Yes — it can be configured to run repeated cycles for fatigue and life-cycle testing, with results logged at each cycle.
Is the data capture software included, or a separate option? +
Included as standard — automatic torque capture and pass/fail evaluation aren’t a paid add-on.
