Haida tells you how to choose a single column or double column tension machine
Rally machines can be divided into single-column and dual -column machines according to the tolerance values . Since different materials require different pull forces when testing, it is also necessary to choose the right puller product.
Different materials require different fixtures, which is also an important factor in the success of the test and the accuracy of the test results. For general flexible packaging manufacturers, or to make some adhesive products, a pulling force range of 100N is sufficient. Therefore, it is also decided to use a single arm type. For some wire rods , rigging and other industries, the product test force often exceeds 500KG. At this time, if you choose single-arm tensile testing machine can not meet the test needs, and you should choose a two-column tensile testing machine, in order to achieve the purpose of testing ! For some metals, building materials and other industries, the test force is generally relatively large, so we should choose the gantry type tensile testing machine to meet the test needs!
Since the flexible packaging material is mainly a high molecular polymer or its related materials, the elongation rate of the high polymer material as described above is far superior to that of metals, fibers, woods, plates, and the like, so the tensile force machine for testing high polymer is used. There is a certain difference between the tensile force tester and the normal material tensile force tester. In particular, it is necessary to pay attention to the effective stroke of the electronic tensile machine and the sample holder.
Whether you choose a single-column type or a dual-column type, you need to pay attention to the suitability. According to the power value and the customer's needs, choose a suitable pull machine.
