Puncture force determination method for universal testing machine

Universal testing machineIt is mainly used for mechanical properties such as stretching, compression, bending, shear, puncture, yield, elastic modulus of materials, metal materials, non-metallic materials and products. This machine is digitally explicit, uses frequency conversion speed regulation, automatic shutdown when it breaks, and can set automatic return, which is very easy to operate. The sensor measures the force, displays the force value digitally, has clear intuitiveness, high measurement accuracy, and automatically saves the break force value.

Designed and manufactured according to the requirements of the "Puncture Force Determination Method for Glue Plug and Gaskets for Injection". Things to note when measuring the gasket puncture force: Treat the gaskets, first take 10 gaskets to be tested, put them in a high-pressure steam disinfector, keep them at 121℃±2℃ for 30 minutes, and take them out and cool them to room temperature. If the elastomer used in the plastic combination cover for large-capacity injection cannot be maintained at 121°C±2°C for 30 minutes, the gasket should be pretreated at the sterilization temperature used in actual production. When performing the gasket puncture force measurement method, take a pretreated gasket, place it in a support device, place the puncturer on a material testing machine to fix it, and pierce the gasket marking area vertically at a speed of 200 mm/min to record the force value applied to pierce the gasket.

Take another gasket and repeat the above steps until all 10 gaskets are pierced once. Before using the piercing device, check the sharpness of the piercing device. The piercing device of the electronic universal tester should keep its original sharpness undamaged.

The result shows that the force value applied to the puncture gasket is expressed by Newton (N).

Universal Testing Machine The universal tester puncture universal tester meets the parameters:

1. Force measurement resolution: 0.001-0.1N (determined by the range))

2. Force measurement accuracy: within ±0.01

3. Tensile speed range: 1mm/min-500mm/min (special requirements are specified separately)

4. Stroke: 800mm (excluding clamp)

5. Extended automatic tracking range: 800mm

6. Power supply voltage: AC220V 50Hz

Introduction to the functions of the puncture force determination method of universal testing machine:

1. Automatic calibration: The system can automatically realize calibration of display accuracy;

2. Manual shift: Manually switch to the appropriate range according to the magnitude of the test force to ensure the accuracy of the measurement data;

3. Display method: LCD display, direct display of force value data, automatic display of elongation value, and display of test curve;

4. Break judgment: After the sample is broken, the moving beam will automatically stop moving;

5. Limit protection: It has two levels of limit protection functions: mechanical and program control;

6. Multi-purpose one machine: equipped with different sensors, which can achieve multi-purpose one machine.
