Plastic Bottle Torque Tester

Plastic bottles are one of the common container forms in drug packaging, especially for oral solid and liquid drugs, as well as various external preparations. As a key component to ensure the sealing integrity of packaging systems, the torque value (i.e. torque) of bottle caps during locking and opening is the core indicator for measuring packaging quality. This seemingly small mechanical parameter is actually of great significance: insufficient locking torque may cause the bottle cap to loosen during transportation and storage, leading to drug moisture, oxidation, contamination, and even leakage, seriously affecting drug stability and safety; Excessive opening torque can cause medication barriers and reduce medication adherence for patients, especially children, the elderly, or those with insufficient hand strength. Therefore, precise and reliable quantitative testing and control of bottle cap torque is an important part of the quality assurance system in modern pharmaceutical industry.

1、 The Scientific Principles of Torque Testing and the Core Value of Quality Control
Torque testing simulates and quantifies the mechanical process of manually tightening or opening bottle caps through precision machinery and sensing technology. Securely clamp the sample with a lid (such as a medicine bottle, plastic ampoule, or hose) in a specialized fixture, and the instrument drive system drives the bottle body or cap to rotate at a constant and programmable speed. During the rotation process, the high-sensitivity torque sensor continuously monitors and records the resistance torque variation curve on the rotating shaft in real time. The peak values on this curve correspond to the "locking torque" (the tightening force required to ensure sealing) and the "opening torque" (the loosening force required to break the initial static friction), respectively. By accurately measuring these values, enterprises can achieve multiple quality control goals: optimizing the parameter settings of the capping machine on the automatic filling production line to ensure consistent sealing of batch products; Evaluate the impact of different batches of bottle caps, bottle body materials, or thread designs on the unscrewing feel; Provide data support for product design, ensuring child safety while also considering elderly friendly opening.Plastic Bottle Torque TesterThe objective data provided serves as a bridge connecting packaging design, production processes, and end-user experience.

2、 Detailed explanation of innovation in core technology and performance advantages of instruments
To meet the high standards of data accuracy, testing efficiency, and regulatory compliance in the pharmaceutical industry, this instrument developed by Jinan Xio Electromechanical integrates multiple technologies:

1. Stable and reliable control coreAdopting an industrial grade PLC control system, it has stronger anti-interference ability and long-term operational stability compared to traditional microcontrollers, ensuring high repeatability and reproducibility of test results and providing reliable basis for quality control decisions.

2. High precision sensing and transmission systemEquipped with a high-precision torque sensor (accuracy level 0.5, resolution 0.001Nm) and a precision servo motor and ball screw transmission mechanism, it achieves smooth and impact free precise rotation. The speed can be infinitely adjusted within a wide range of 0.01 to 25 RPM, meeting the testing requirements of different standards.

3. Intelligent human-computer interaction experienceEquipped with a 7-inch high-definition HMI touch screen, providing an intuitive graphical user interface. Users can easily set the test mode (lock/open), target torque, rotation speed and direction, and observe the dynamic torque angle curve in real time. All test data and statistical results are clear at a glance, greatly reducing the difficulty of operation.

4. Adaptability and scalability: The standard fixture is compatible with samples with diameters ranging from Φ 10mm to Φ 170mm, and pneumatic fixtures or special clamping jaws can be customized to fit various special-shaped bottles, hoses, spray cans, etc. The instrument is not only used for medicine bottles, but can also be extended to torque testing of food and beverage bottle caps, cosmetic packaging, and even industrial fasteners.

5. A comprehensive data management and traceability planThe instrument has a built-in micro printer that can output test reports in real time. At the same time, RS232 interface and professional computer software can be optionally configured to achieve high-capacity storage, statistical analysis (such as mean, standard deviation, CPK calculation), trend chart generation of test data, and support data export and archiving in accordance with GMP/GLP specifications, ensuring data integrity and traceability.

3、 Strict compliance with standards and wide industry applications
The design and calibration of this instrument strictly follow the core standards of the packaging industry at home and abroad, ensuring the wide recognition of test results:

• Mainly compliant with standardsInternational standards such as GB/T 17876 "Plastic anti-theft bottle caps for packaging containers", BB/T 0025, BB/T 0034, and ASTM D2063.
