DeMattia Flex Cracking Tester for Rubber Samples Test

DeMattia flex cracking tester manufactured by Wewon Environmental Chambers Co., Ltd. is mainly used to determine the fatigue resistance of vulcanized rubber after repeated expansion and contraction under high and low temperature conditions. After the test samples are exposed to different temperature environments for a certain period of time in the test, compare the differences between before and after the test. For example: the rate of change of deformation, elongation, hardness, etc.

The Wewon’s De Mattia flex cracking and cut growth test machine is composed of mechanical transmission part, oil source, high and low temperature test room, full digital servo controller and test accessories. The test sample is dynamically compressed vertically and horizontally at a constant pressure to fatigue it. The machine can be used to detect whether it can withstand a specified number of reciprocating pulling operations under the action of transverse and longitudinal tension.

The DeMattia flexing machine from Wewon Tech is a test method to determine the occurrence and growth of cracks by repeatedly giving vulcanized rubber and thermoplastic rubber bending deformation. Fix the test sample on upper and lower two chucks placed in parallel, and perform reciprocating motion on the same plane to make it bend.

The De Mattia flexing machine is a testing instrument that evaluates the durability of rubber materials and highly stretchable fiber materials due to repeated bending and fatigue after repeated expansion and contraction. Evaluate the durability of the test sample until the occurrence of rupture, the elongation residual rate after a certain number of tests, or the traction strength after a certain number of tests.

The De Mattia flexing tester for leather,shoes, rubber test is equipped with a commutation device that controls the speed, and the speed can be changed freely by simply operating the speed rotary knob. The set speed is displayed on the speed display in digital form. The number of tests and the time of contact test can be set, which is very convenient to use.

The low temperature DeMattia flexing tester manufactured by Wewon has a sturdy structure and can install 16 samples for measurement at the same time. The observation window is at a comfortable working height. A movable light strip can be measured in a reproducible field of view. The machine is controlled via a touch screen. In automatic mode, The timer indicates to observe the current remaining time and the machine automatically stops at the specified position.

Further more, The De Mattia type flexibility test equipment from Wewon Tech can be stopped at any time when performing standard tests, or restarted after stopping to continue running tests. This machine design can achieve high load, high frequency and low consumption, thereby shortening the test time and reducing your test costs. Due to the simple structure, easy operation, high efficiency and low energy consumption of the machine features, Wewon’s DeMattia flex cracking testers are favored by the scientific research and teaching departments of aerospace, aviation and other institutions of higher learning.

There is no doubt that the development of DeMattia flex cracking test machines in the future will be more humane. From equipment conception to design, production to sales and to our users, every step is based on humanity as the first consideration. It can be better and more convenient for us to use, for example, ergonomic equipment design and so on. In general, There are many types of fatigue and lifecycle simulation testing machines, but one type of testing machine can only do one type of test.

Although there is a universal testing machine on the market, is it really omnipotent ? This understanding is not correct. In the development of DeMattia Flexing testing machines in the future, the functions of itself will also be integrated. One testing machine can do several types of tests and truly realize multi-functions. The development of science and technology can promote the update of DeMattia flexing testers, and these DeMattia flex cracking testers will also be more humanized, intelligent and functional.

With the development of microelectronics and computer technology and the improvement of testing methods, DeMattia flex cracking testers’ use functions are being continuously expanded. In recent years, With the development of China’s testing machine technology, The end user have paid more attention to the process of dynamic testing. One, the demand for high-frequency low temperature DeMattia flexing testers has also begun to show an upward trend.

The De Mattia type flexibility test equipment is used to test the fatigue fracture resistance of materials, and can draw the fatigue life curve. It is equipped with a variety of special fixtures and can be used to test the fatigue life of various parts. At present, Many colleges and enterprises will use it for fracture Toughness test, testing the crack growth rate of metal materials and the threshold value of the material. At the same time, We must also see the possibility that the rubber fatigue and DeMattia flex test machine will be more intelligent in the future development.

For example, It can intelligently turn on and intelligently shut down, and intelligently automatically grab samples, transmit and compare data in real time during the test, and then intelligently remove the sample to save the test data after the test is completed. And then grab another sample to be tested.
