Several Aspects Needing Attention in Purchasing Tensile Testing Machine

April 19,2022

With the continuous development of social science and the continuous improvement of product quality, products need a tensile test, compression test, tear test, peel test, etc. tensor tensile test machine is also known as a material testing machine, leather tensile strength testing machine, shoe tensile strength testing machine, tensile testing machine, machine for tensile test, tensile stress test machine, etc.

tensile testing machine

Classification

Divided by appearance: single column tensile strength testing machine (floor type and table type), double column tensile strength testing machine (floor type and table type)

Divided by function: servo tensile strength testing machine and ordinary tensile strength testing machine

According to horsepower: microcomputer tensile strength testing machine, computer tensile strength testing machine

How to choose a suitable tensor tensile test machine for your factory?

Test system

Choose a microcomputer or computer. Generally, a microcomputer can only display the obtained tensile value, but the elongation can be achieved according to the needs of customers. Of course, it is more economical. If you need to see the force value curve, you must recommend a computer-based tensor tensile test machine, which can display a variety of curves, and all of them are operated on the computer control interface, The force value curve report can be printed through the printer.

Speed requirements

If the speed requirement is not very high during the test, it is generally completed by using a variable frequency motor with a speed regulator. If the test speed is very high during the test, if it is within the range of 0.1 - 500, we must use a servo motor with a servo system.

Test capacity

Generally, a single column tensor tensile test machine is used for tensile tests less than 200kg, and a double-column tensile test is used for tensile tests greater than 200kg.

Test stroke (i.e. the space required by the test object for the tensile test and a distance required during the test).

To ensure a certain distance during the tensile process of the sample.

Precautions for customers to purchase a tensor tensile test machine

Test capacity

The specimen is stretched to a large range of required force values.

Test speed

The speed depends on the motor used and also determines the cost of the tensile stress test machine. The variable frequency motor can only achieve 25-300mm / min or 50-500min / min, while the servo motor can reach 1-500mm / min, but the cost will increase a lot accordingly. Therefore, please confirm your test speed range when purchasing.

Test stroke

Is the test space and length range required in the tensile process of the sample?

Elongation between two points

Elongation refers to the length extended by the sample breaking, refers to the small deformation, and the elongation between two points refers to the length extended by a part of the test sample during the test process, that is, refers to the large deformation, which needs to be equipped with a large deformation fixture to complete the test.
