According to different levels of customer requirements, tensile testing machines are mainly divided into the following three types:

Microcomputer controlled single arm electronic tensile testing machine, digital display electronic tensile testing machine, microcomputer controlled portal electronic tensile testing machine

Testing the tensile properties of rubber samples is one of the important indicators of rubber quality testing. Almost all the quality laboratories of rubber related industries will be equipped with one or more rubber tensile testing machines. But the author found in the maintenance, in fact, many laboratory rubber tensile testing machine configuration may not be able to fully meet the requirements of the relevant standards. This is not only due to the unprofessional selection personnel of the user testing machine, but also due to the inadequate communication of the sales personnel of the manufacturer. Of course, there are also some reasons why most users of industrial and mining enterprises do not have a strong sense of standards and are reluctant to invest.

Tension machine can be divided into single column tension machine and double column tension machine. Because different materials need different pulling force when testing, it is necessary to choose the appropriate pulling machine products.

Different materials need different fixtures, which is also an important factor of whether the test can be carried out smoothly and the accuracy of the test results. For general flexible packaging manufacturers, or do some adhesive products, the tension range of 100N is enough. Therefore, it is also decided to adopt the single arm type. For some wire, rigging and other industries, the product test force is often more than 500kg, at this time, if you choose the single arm tensile testing machine can not meet the test needs, and should choose the double column tensile testing machine, in order to achieve the purpose of testing! And for some metal, building materials and other industries, the test force is generally large, so we should choose gantry tensile testing machine to meet the test demand!

As the flexible packaging materials are mainly high polymer or its related materials, as mentioned above, the elongation of high polymer materials is far better than that of metal, fiber, wood, plate and other materials, so the tensile testing machine for high polymer is different from the general tensile testing machine, especially the effective stroke of the electronic tensile machine and the sample clamp There are two aspects.

Whether it is the choice of single column or double column tension machine, we need to pay attention to the applicability, according to the force value and customer demand, choose the right tension machine.
