How to choose a Tensile Testing Machine?

At present, there are many brands of Tensile Testing Machines on the market, and there are many types of tests, and the price and quality are uneven. So as a buyer or business owner, how should we choose a pull Tester? How to judge which brand of Tensile Testing Machine is good? What is the reference? Let me do a detailed analysis for you.

When shopping for a tensile Tester, you're likely to look at three principles: testing needs, machine performance, and manufacturer service. First, select a Tensile Testing Machine with appropriate specifications and parameters according to the type of test. In addition, Tensile Testing Machines have high requirements for both hardware and software, so it is necessary to choose a suitable manufacturer based on service and quality. Here are the details.

Determine what tests are needed?

Determine which tests to perform to determine which instruments we need to purchase. First of all, we need to make sure that we choose the right machine, in case the machine we buy is not what we imagined, because in some industries, some tests are dedicated to special machines.

For example, spring tensile fatigue test, in theory, a Tensile Testing Machine is also possible, but a good test instrument is not a Tensile Testing Machine, but a spring fatigue testing machine, which is a machine specially built for spring testing. Another example is a rubber 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 elongation. However, due to the large deformation of rubber when stretched, especially latex products, its elongation may be as high as 1000%. Therefore, before the rubber sample breaks, it is necessary to ensure that the effective stroke of the Tensile Testing Machine is large enough, and it is necessary to use it with a large deformation extensometer. so,

Determine the maximum test force for a material?

Determining the maximum destructive force can determine the range of the tensile machine, because it distinguishes the model of the tensile machine according to the range of the sensor. First of all, different machine sensors have different ranges. In addition, the Tensile Testing Machine has different accessories such as screws, motors, and gearboxes. The structure of the Tensile Testing Machine will also be different, for example: the range of 0-500kg is a single-column tensile instrument, the range of 1-20T is a double-column electronic tensile instrument, and the range above 30T is a hydraulic multi-column electronic tensile instrument.

Judging whether the function meets the requirements?

Determine which tests the Tensile Testing Machine can do: computer-based Tensile Testing Machines can generally perform tests such as tension, compression, bending, peeling, tearing, shearing, puncture, and low fatigue, but some simple digital Tensile Testing Machines cannot Perform peel test, fatigue, shear and other functions.

Determine whether the test stroke and test speed are consistent?

The test stroke is determined according to the characteristics of the material. The stroke of hard materials such as metals is usually not very large, and the standard testing machine can meet the requirements. However, some flexible packaging films, rubber, silica gel and other materials have a large test stroke, and some may need to increase the stroke of the tensile instrument to meet the measurement. The test speed is also an important parameter of the tensile machine. Generally, the test speed range of the tensile machine is 0.1-500mm/min, which can meet most of the test requirements. Some special products may require a test speed of 1000mm/min or even greater. It needs to be determined in advance.

Determine the brand of the core parts of the machine?

We all know that the core components of the tensile machine are: sensors, screws, motors, gearboxes and even controllers. Tension machine manufacturers at home and abroad do not have a single part that is 100% produced by themselves, so the outsourcing of some core parts also involves the brand of these parts. A good brand not only has better precision, quality and convenience, but also has an important impact on the overall performance, stability and reliability of the machine. Therefore, the core accessories are also used as an important basis for comparison.

Determine whether the accuracy of the machine meets the requirements?

The accuracy standard of ordinary Tensile Testing Machine is level 1, that is, the accuracy of the machine is within ±1%; of course, there is a higher level of 0.5, and the measurement accuracy error is within ±0.5%. When choosing, you can choose according to your actual needs.

Determine whether the brand is a factory direct sale, and whether the after-sales service is guaranteed?

As a tension gauge for self-use, we need to determine whether the supplier is a factory direct sale, and after-sales service is guaranteed. After all, there are many electronic products in the tension gauge, and various failures may occur, so it is equally important to choose a supplier.

Compare prices and choose a brand with a good reputation

After there is no problem with the above, it is time to inspect the price. After all, the price is still very important. Suggestion on price: choose the brand according to your company's budget, don't blindly pursue big brands, but never buy at a price far below the normal market price, unless you buy it just for viewing.
