The SureTorque features a servo drive control, infinite chuck rotation, quick-change tooling, a color touchscreen interface, and faster cycle times.

The corrosion resistant stainless steel head enclosure and anodized aluminum frame construction makes SureTorque ideally suited for the most demanding applications, such as testing closure torque at Carbonated Soda Drink (CSD), juice, bleach bottling operations as well as cleanroom environments.

The unit is equipped with anti-bridging, anti-tie down anti-repeat dual actuation safety start switches, but for maximum operator safety, the SureTorque can be also equipped with a full machine guard.

  • Encoder to measure angular degree of rotation
  • Heavy duty components

Testing Capabilities

  • Applied Torque: The SureTorque or ST-120 can be used as a benchtop capper, tightening the cap to a customer defined setpoint.
  • Release Torque: The ST-120 is designed to accurately measure the release (thread break) torque of a cap.
  • Peak/Transient Torque: The standard ST-120 can measure and display the Applied or Release Peak in a torque testing cycle, however with optional hardware upgrades it is also possible to measure certain torque transients such as the engagement torque of a CR closure system or the peak of the bridge break torque of a Tamper Evident Band.
  • Container/Closure Fatigue: By allowing the ST-120 to apply and release the cap a number of times, it is possible to evaluate the effect of fatigue on the torque retention and seal quality of the closure and seal.
  • Release and Re-apply Torque: When packaging expensive products it is often required to return the tested container to the packaging line. By automatically re-applying the torque to the operator defined setpoint it is possible to save the product.
  • Topload Force (optional): This feature allows the monitoring and control of topload force. When testing child resistent caps or other closures requiring topload adjustment this feature allows the evaluation of topload force in the function of rotation and torque.
