300N suture circular tensile fatigue testing machine

PWS series microcomputer controlled dynamic and static fatigue testing system is one of the series of dynamic fatigue loading testing system products developed by our company.This series of products has the characteristics of wide output range, high control accuracy, easy use and high reliability.This series of test systems are designed by absorbing internationally advanced electric servo cylinder drive technology during the research and development process and taking into account the actual usage conditions of domestic users.Key components such as servo actuators, imported materials, and loading frames are designed and manufactured by our company, and the controller is independently developed, which greatly improves the stability and reliability of the system.

300NSuture circular tensile fatigue testing machineIt can not only carry out dynamic high and low cycle fatigue tests, program-controlled fatigue tests, but also static constant rate, constant strain, constant stress controlled tests and various conventional mechanical property tests. It can also carry out fracture mechanics tests. It can also conduct fatigue life, crack propagation, fracture toughness performance tests of materials or components in a broad range, safety evaluation of actual specimens, working condition simulation, etc. Therefore, it has advantages that cannot be matched by any other type of testing machine. It is the most respected material testing equipment in the field of international fatigue mechanics research.

Since this system uses an adaptive and gapless electric servo actuator, it has fast frequency response, low noise, energy saving and environmental protection. It is very suitable for enterprises and research institutions to research and test small parts!
