Scope of application
Buffer strength tester for packaging materials The buffering characteristic of material is the basis of packaging structure design, only know the buffering characteristic of material, can have a good buffering packaging set. Meter, buffer material coefficient testing machine is to test the cushioning of material testing machine. Used in packing carton, sponge, foam and other products, the application range is very wide.
System features
(1) The self-developed velocity detector is used to accurately measure the instantaneous velocity at the beginning of the impact
(2) The impact acceleration time signal can be collected reliably under any circumstances
(3) Provide a variety of FIR digital filters to filter the acceleration signal to ensure that the signal will not be distorted, which is particularly important for the study of the mechanical properties of buffer materials and the development of new buffer materials.
(4) The curves of large acceleration - static stress, buffer coefficient - large stress and dynamic stress-strain are displayed in a linear or logarithmic manner
(5) Provide a variety of curve fitting schemes, especially manual fitting, more convenient for you
(6), fully automatic naming files, without human intervention
(7) A graph multi-line tool enables you to place multiple curves on a graph with linear or logarithmic coordinates, which provides convenience for the study and comparison of mechanical properties and buffering properties of various materials in different situations
(8) Even if the test is interrupted for some reason, the data will be automatically saved, and the subsequent test does not need to start from scratch
(9) Press the test report button, and the test data will automatically enter the test report of Word version.
System application
(1) Use the static stress curve of the larger acceleration or the stress curve of the larger buffer factor obtained by the test to carry out the buffer packaging design
(2) When developing new cushioning materials, study the mechanical properties of materials, cushioning properties and their relationship by using the impact acceleration time curve, dynamic stress-strain curve, static stress curve of large acceleration or stress curve of large cushioning coefficient obtained from the test.
(3) Cushion material manufacturers to provide customers with a variety of brands, density of buffer materials under various test conditions of the greater acceleration curve and buffer coefficient curve
(4) Analysis and improvement of buffer performance of original transport packages, design and improve buffer packaging
