Product Introduction:

1. The PWST-5 electro-hydraulic servo dual channel copper wire fatigue testing machine is used for fatigue life testing of building materials wires and drawn wires, such as wires, contact wires, copper wires, copper alloy wires, and wire ropes. It can also be used for dynamic and static mechanical performance testing of materials and components, including tensile, compressive, low cycle, and high cycle fatigue tests. Configure high and low temperature chambers for conducting high and low temperature mechanical tests.

2. The research and development process of the electro-hydraulic servo dynamic and static series testing machine draws on the development and manufacturing experience of the International Electro Hydraulic Servo Dynamic Testing Machine Company, adopting the development concept of "unitization, modularization, and standardization", absorbing international electro-hydraulic servo dynamic testing machine technology, and designing it based on the actual usage conditions of domestic users. The key supporting components of the electro-hydraulic servo dynamic testing machine are selected from international and domestic brands of similar products. Greatly improving the stability and reliability of the system, the key units and components of the system are manufactured using current international technology, and the overall performance of the entire testing system is comparable to the product technology level of International Dynamic Testing Machine Company. This series of products has the characteristics of easy use, high control accuracy, and good reliability.

3. The electro-hydraulic servo dynamic and static testing machine is one of our company's newly developed series of dynamic and static testing machine products. The main unit of the testing machine, constant pressure servo pump station, hydraulic chuck and other key components are designed and manufactured by our company. Key purchased parts such as servo valves and seals are selected from international and domestic brands of similar products, greatly improving the stability and reliability of the system. The overall performance of the testing machine is comparable to the international product technology level.
