Choose suitable tensile testing machine in 5 aspects

Tension testerThere are many models and various performances. The following are the precautions for selecting tensile test machines.

1. First of all, the company should consider what tests it needs to be done. The tensile test machine can be used to test materials such as tensile, compression, bending, shearing and peeling by replacing different fixtures. Of course, the tensile test machine has different models and different fixtures, and the prices are also different.

2. Also consider the tension range. For general flexible packaging manufacturers, the tension range is about 200N, that is, single-armed ones, and more than one ton of the steel manufacturer must use the door type. For example, steel manufacturers should consider using such or larger...

3. Measurement speed

The speed specified by the national standard is 200mm/min. The market equipment has between 10 and 500mm/min, and 0.001 and 500mm/min or even higher accuracy. The former generally uses ordinary motors, which are invigorating speed, have lower accuracy and cheaper prices; the latter uses servo motors, computer servo systems, with higher accuracy and higher resolution; purchase according to the needs of each manufacturer.

4. Accuracy

Including force measurement accuracy, speed accuracy, deformation accuracy, and displacement accuracy. These accuracy values ​​can reach plus or minus 0.5, which is enough for the accuracy of amplitude of 1% for ordinary manufacturers. In addition, the resolution of force values ​​can basically reach one hundred thousand.

5. Sample size

Another one is the sample size and the stroke of the test machine. The stroke of the tensile test machine on the market is generally between 600mm-800mm-1000mm. Our sample size cannot exceed the stroke of the test machine. If it exceeds it, it needs to be specially customized. However, the parts materials for testing products should be suitable for most manufacturers.
