Although the electronic universal testing machine and hydraulic universal testing machine belong to the mechanical…
Universal tensile tester, also known as electronic tensile testing machines, can be used for a variety of materials for tensile, compression, bending, shear, tearing, peeling, and other mechanical performance tests. Due to the powerful function and wide range of application of electronic tensile tester, many companies need to purchase universal electronic tensile tester.
Now there are many brands of electronic tensile testing machines on the market, with many types of tests and varying prices and quality. So as a buyer or business owner, how should we go about choosing an electronic tensile tester? How to determine which brand of the electronic tensile tester is good? What is the reference basis? Below I will do a detailed analysis for you.

★ 7 Bases for Choosing an Electronic Universal Tensile Tester
When buying an electronic universal tensile tester, you will probably follow three principles: testing needs, machine performance and manufacturer service. Firstly, choose a tensile testing machine with the appropriate specification parameters according to the type of test. In addition, the tensile tester has high requirements for both hardware and software, so choose the right manufacturer based on service and quality. Here are the details.
1 Determine what tests need to be done?
Determine what tests to do in order to determine what instruments we need to buy. First of all we must make sure that we choose the right machine to prevent the machine that buying back is not what we thought it would be, because in some industries some tests are dedicated to special machines.
For example, the spring tensile fatigue test, in theory, the electronic tensile tester can also do, but the best test instrument is not an electronic tensile tester, but a spring fatigue test machine, which is a professional built machine for the spring test. Another example is the rubber electronic tensile testing machine. We all know that rubber products need to be tested for tensile damage in order to test their mechanical properties such as tensile strength and extension. But because the deformation of rubber is very large in the stretching, especially latex products, elongation may be as high as 1000% or more. So before the rubber specimen breaks, it is necessary to ensure that the effective stroke of the tensile tester is large enough, it is necessary to use it in conjunction with the use of a large deformation extensometer. Therefore, it is more important to choose the right one than a good one.
2 Determine the maximum test force of the material?
Determine the maximum destructive force will be able to determine the range of the electronic tension machine, because it is based on the range of the sensor to distinguish the model of electronic tensile tester. First of all, different ranges of the machine sensor is different, in addition, the screw, motor, gearbox and other accessories of electronic tensile testing machine are different, and finally, the structure of the electronic tensile tester will also be different, for example: 0-500kg range are single-column type electronic tensile tester, 1-20T range is double-column type electronic tension machine, more than 30T range are hydraulic multi-column type electronic tension machine.
3 Determine whether the function meets the requirements?
Determine what tests the electronic tensile tester can do: computer-type electronic tensile tester can generally achieve tensile, compression, bending, peel, tear, shear, puncture, low fatigue and other tests, but some simple digital display type electronic tensile tester can not test the peel, fatigue, shear and other functions.
4 Determine whether the test stroke and test speed are consistent?
Test stroke is based on the characteristics of the material to determine, the stroke of metal and other hard materials is usually not very large, the standard testing machine can meet. But some soft packaging film, rubber, silica gel and other materials, the test stroke is very large, some may need to increase the stroke of tensile tester to meet the measurement. Test speed is also an important parameter of the electronic tensile tester, the general electronic tensile tester in 0.1-500mm/min, this speed range has been able to meet the majority of test requirements, some special products may require 1000mm/min or even greater test speed, these are required to determine in advance.
5 Determine the brand of the core spare parts of the machine?
We all know that the core parts of the electronic tensile tester are: sensors, screw, motor, gearbox and even including the controller, etc. Domestic and foreign manufacturers of tensile tester, none of the accessories used 100% of their own production, so some of the core accessories are outsourced, which also involves the brand of these accessories. A good brand not only precision, quality convenience better, for the overall performance of the machine, stability, reliability also has an important impact. Therefore, the core accessories are also used as an important basis for comparative reference.
6 Determine whether the brand is directly sold by the manufacturer and whether the after-sales service is guaranteed?
As an electronic tensile tester for their own use, we have to determine whether the supplier is a factory direct sales, after-sales service is guaranteed, after all, there are many electronic products of the electronic tensile tester, there may be all kinds of failure, so the choice of what kind of supplier is equally important.
7 Compare prices and choose a brand with a good reputation
After the above is no problem, the last is to examine the price, after all, the price is still very important. On price advice: according to your company’s budget to choose a brand, not the blind pursuit of big brands, but definitely not to buy far below the normal market price, unless you buy just use to see.
★ Brand Recommendations of Electronic Universal Tensile Tester
In addition to assessing the brand from the quality of the electronic tensile tester, we can also assess them by after-sales service, compliance with testing standards, simplicity of operation and price. Here is a brief list of some of the better brands to meet different purchasing needs.
Japan Shimadzu tensile testing machine. Japan’s electronic technology has been very well developed, its Panasonic AC servo motor in various industries can be seen, and Japan’s NTS sensor is also a well-known sensor worldwide.
Germany ZWICK tensile testing machine. German industrial manufacturing is indeed the heritage of the times, exquisite craftsmanship dedication plus Schneider series brand accessories, so that ZWICK tensile testing machine wears the top title.
MTS tensile testing machine from the USA. The United States MTS tensile testing machine is famous for its stability, no matter what, its quality is guaranteed, is a hundred-year tradition of the old brand.
American Instron tensile testing machine, 1946 to the present well-known historical brand, belongs to the quality is still good instrument.
Taiwan Gotech tensile testing machine, Taiwan has always been known for quality and dedication, but also a world-renowned brand.
Guangdong TESTEX tensile testing machine, test stable, specifically for rubber, plastic, fibers and other organic polymer materials, more professional.
