Brand: Jiubin
Name: Electro-hydraulic servo dynamic and static universal spring fatigue testing machine
一、product description：
　　Electro-hydraulic servo dynamic and static universal spring fatigue testing machine is a series of new products developed by our company. This series of products have the characteristics of easy use, high control accuracy, and good reliability.
　　It is widely used in dynamic and static mechanical performance tests of materials and parts, including compression, low-cycle and high-cycle fatigue tests of materials and parts. It can be used for crack propagation fracture mechanics of various materials and various other mechanical tests by configuring corresponding accessories and test software. Equipped with high and low temperature box, high and low temperature mechanical test can be carried out.
