Instruments for measuring torque when screwing caps – an important part of product quality control. Torsiometers allow you to prevent product defects, leakage or damage to products during transportation and further use. Optimal torque setting is an important factor in the manufacture of products, influencing the evaluation of the product by the consumer. Difficulties with opening a bottle can cause irritation and dissatisfaction, precede a negative impression of the product. At the same time, insufficiently reliable closure will lead to a violation of the tightness of the container, which is also unacceptable.
Sturdy, lightweight and portable Torque Testers are specifically designed to measure low torques and apply to any rotating part . The devices are equipped with technology to determine the exact torque values of products, especially in the beverage and pharmaceutical industries. The widespread use of devices when working with various mechanical systems is associated with a reliable design and an intuitive operation scheme. Torque testers are used in the automotive and aviation industries when assembling parts and fasteners. Devices are also needed to secure connections in electronics, install various equipment in the energy industry and control the safety of construction products. Torsiometers are especially relevant in the production of packaging materials, for closing containers and plastic bottles cups.
Types of Torque Testers and Features of Their Use
Depending on the characteristics, needs and tasks, Tork testers are divided into several types: manual, digital and semi-automatic.
Portable hand-held devices are equipped with an accessible control system and, despite the simplicity of the mechanism, do not lose their relevance. Each instrument has an electronic display to show measurements. The torque tester is set manually, making it possible to monitor the closure values.
Digital Torque Testers are often equipped with automatic data logging features that allow the operator to easily read the performance of the controlled sample. The advanced functionality of the device and the scope of settings simplify the process of control and analysis. In turn, semi-automated devices combine both manual and automated tools. This combination allows you to achieve higher accuracy, repeatability and productivity.
Non-destructive testing methods – quality guarantor
Torque Test — this is a technical test that is performed to determine the maximum torque. It is a measure of the force that can be applied to an object, equipment, or system without damage or deformation.
The main testing steps are:
- ✅ equipment and sample preparation;
- ✅ Installing gauges;
- ✅ test procedure;
- ✅ data monitoring and analysis;
- ✅ result documentation.
Samples are pre-installed on torque test benches, subjected to an impact force that gradually increases to a certain value. The clamping chuck firmly fixes the lid of the container under observation.
The handheld instrument is placed on the test specimen and the operator rotates it counterclockwise while holding the container body in the other hand. The torque value is shown on the display. This data helps determine what maximum torque can be sustained.
Non-destructive testing of products at the Preform Factory — An important step in the manufacturing and management process that is performed to ensure that a product meets certain standards, specifications, and requirements. Mandatory testing of manufactured products guarantees high quality and safety.
