Product Introduction 
The Cup Body stiffness tester operates on a radial compression principle. A pair of specified probes applies radial pressure to the cup body from both sides at a constant speed, simulating the gripping force of a hand holding a paper cup during actual use. A high-precision load cell captures real-time force changes during the compression process, and the single-chip microcomputer control system automatically identifies and records the maximum force value as the cup body stiffness test result. The instrument is equipped with an automatic loading system, and the probe gap can be adjusted within a range of 40-120 mm to accommodate paper cups of different specifications. Test data can be automatically stored, statistically processed, and output as a report via the built-in printer.

Main Technical Specifications

FAQ 
1. What products is the cup body stiffness tester suitable for?
It is suitable for measuring the body stiffness of various paper cups, paper bowls, ice cream cups, and other paper containers, provided the cup body dimensions fit within the probe gap adjustment range of 40-120 mm.

2. What is the testing principle for cup body stiffness?
The instrument applies radial pressure to the cup body via a pair of probes, simulating the gripping force of a hand. It measures the resistance force at a specified deformation or the maximum compressive force to evaluate the cup body stiffness.

3. How should the probe gap be set?
The probe gap can be adjusted within the range of 40-120 mm according to the diameter of the paper cup being tested and testing requirements. The gap is typically set slightly smaller than the cup body diameter to ensure good contact between the probes and the cup.

4. Does the instrument require a voltage stabilizer?
If the power supply voltage exceeds 220V or fluctuates significantly, an AC voltage stabilizer must be used to ensure proper instrument operation and prevent measurement errors or equipment damage caused by voltage instability.

5. How does the fault self-diagnosis function help with troubleshooting?
The instrument has a built-in fault self-diagnosis program. When system abnormalities occur (such as sensor failure, motor abnormality, or communication interruption), it automatically indicates the fault type and possible cause, allowing users to quickly troubleshoot or contact after-sales service.

6. How are test results printed?
The instrument has data processing capabilities. After testing is completed, a test report containing statistical results of all data can be printed directly via the built-in printer (or an external printer).
