1. PWS series electro-hydraulic servo dynamic and static universal testing machine , also known as electro-hydraulic servo fatigue testing machine , is easy to use, high in control accuracy, and reliable. It is used to test the dynamic and static mechanical properties of various metal and non-metal materials, such as tensile, compression, bending, high and low cycle fatigue, fracture toughness, crack growth and other mechanical tests. At the same time, the addition of corresponding fixtures can also be applied to the dynamic performance, static performance and fatigue life of various structural parts and components. The main components of the system: host, constant pressure servo pump station, hydraulic forced test chuck, control system, software system, etc.

2. The PWS series electro-hydraulic servo testing machine host and constant pressure servo pumping station are designed and manufactured by the company. The servo controller is equipped with domestic and imported two types. There are low-end, mid-end, high-end and other types of testing machines to choose from. Each controller is equipped with basic test software, and there are a variety of functional test software for selection.
