Oral solid polyester bottle cap torque meter

Polyester bottles are widely used in the packaging of oral solid drugs such as tablets, capsules, and granules due to their excellent barrier properties, transparency, and durability. As a key sealing component of packaging, the torque value of the bottle cap during tightening and opening directly determines the sealing performance, content stability, and end user experience (especially for elderly or frail patients) of the packaging. Insufficient torque can easily cause the bottle cap to loosen, leading to drug moisture, contamination, or failure; Excessive torque can cause difficulty in opening and affect medication adherence. Therefore, scientific and precise quantitative control of bottle cap torque is one of the core links for pharmaceutical companies to ensure product quality, meet regulatory requirements, and enhance brand reputation.

1、 The Scientific Principles of Torque Testing and the Core Value of Quality Control
Bottle cap torque testing simulates and accurately quantifies the mechanical process of manually tightening or opening bottle caps. During testing, the capped drug bottle under test is stably fixed in a customized fixture, and the instrument drive system drives the bottle body or cap to rotate at a constant and precisely adjustable speed. A high-sensitivity torque sensor monitors the changes in resistance torque on the rotating shaft in real-time and continuously. In the "locking force test" mode, the instrument records the peak torque when tightening the bottle cap to the predetermined position. This data is used to set and calibrate the parameters of the capping machine on the automatic filling line to ensure sealing consistency in mass production. In the "opening force test" mode, the instrument records the peak torque required to initially break the static friction between the bottle cap and the bottle mouth, which directly reflects the difficulty of opening the medication bottle for the patient. by usingOral solid polyester bottle cap torque meterBy conducting system testing and statistical analysis, enterprises can establish precise torque control standards, achieve full process quality control from packaging material incoming inspection, production line process monitoring to finished product release, and find a balance between ensuring drug safety and convenient use.

2、 Analysis of Innovation in Core Technologies and Performance Advantages of Instruments
To meet the strict requirements of the pharmaceutical industry for data reliability, operational convenience, and regulatory compliance, this instrument adopts multiple designs:

1. Industrial grade stability control platformThe core adopts PLC industrial control system, which has stronger anti-interference ability and long-term operation stability compared to ordinary microcontrollers, ensuring high repeatability and reproducibility of test data. Combined with precision servo motors and ball screw transmission systems, it achieves smooth and impact free precise rotational motion with a wide speed control range of 0.01 to 25 RPM.

2. Intelligent human-computer interaction interfaceEquipped with a 7-inch high-definition HMI touch screen, providing an intuitive graphical user interface. Users can easily set test modes, torque limits, rotation direction and speed, and observe dynamic torque angle curves in real time. All test results and statistical information are clear at a glance, greatly reducing operational complexity and training costs.

3. Measurement accuracy and adaptabilityThe instrument has a measurement accuracy of 0.5 level and a resolution of up to 0.001Nm, which can sensitively capture subtle torque changes. The standard fixture clamping range covers from Φ 10mm to Φ 170mm, and can be customized with pneumatic fixtures or special claws, suitable for various specifications of polyester bottles and other packaging containers from small oral liquid bottles to large solid medicine bottles.

4. Dual testing mode and powerful scalabilityLocking and opening force testing modes meet the complete packaging process evaluation requirements. The instrument platform has strong expansion capabilities, which can be easily extended to torque measurement of hose packaging, plastic ampoules, cosmetics, and even industrial fasteners by replacing fixtures, achieving multi-purpose use of one machine.

5. Complete data management and traceability systemBuilt in micro printer can instantly output test reports. At the same time, RS232 interface and professional computer software can be optionally equipped to achieve massive storage of test data, advanced analysis (such as CPK calculation), trend chart generation, and electronic record management that complies with regulatory requirements such as FDA 21 CFR Part 11, fully ensuring data integrity.

3、 Wide range of standard compliance and industry application scenarios
This instrument strictly follows the core testing standards for packaging and pharmaceutical packaging materials at home and abroad, mainly including:

• GB/T 17876 "Plastic anti-theft bottle caps for packaging containers"

• BB/T 0025、BB/T 0034Waiting for relevant packaging standards
