Tips for purchasing tensile testing machine

The products of tensile testing machines are diverse. How to choose a tensile testing machine suitable for my implementation room is a constant trouble for major manufacturers. Let me briefly introduce the methods for purchasing tensile testing machines:
1. At the beginning, you should determine which experiments your company needs to do in the products. Since the tensile testing machine is also called a universal testing machine, it can test the tensile, compressive strength, elongation, and extension of various materials, semi-products and products, and can be peeled off, tear, bending, flexural, tightening, etc. The models of various tensile testing machines are different, the matching fixtures are different, and the prices are of course different.
2. Need to think about the limitations of tension. For ordinary flexible packaging manufacturers, tension is limited to about 200N, that is, single-armed ones, and the larger ones are door-shaped, more than 1 ton. For example, manufacturers who make steel should think about using such things, perhaps even bigger ones...
3. Itinerary,
Depending on the product produced by me, the stroke of the ordinary tensile tester is generally between 600mm-800mm-1000mm. The data on the test product parts should be suitable for the manufacturer.
4. Measurement speed
The speed of national standards is 200mm/min, and the equipment is between 10 and 500mm/min, and 0.001 and 500mm/min or even higher accuracy. The former uses a common motor, which is a non-stop speed changer, with a lower accuracy and a lower price; the latter uses a servo motor, a computer servo system, with a higher accuracy and a higher resolution; purchase according to the needs of each manufacturer.
5. Accuracy
Including force measurement accuracy, speed accuracy, deformation accuracy, and displacement accuracy. These accuracy values ​​can reach plus or minus 0.5. The accuracy of the amplitude of ordinary manufacturers is enough. In addition, the force value resolution can reach one hundred thousand.
