Dynamic and Static Electro-Hydraulic Servo Testing Machine

Model: PLS Series


PLS series dynamic and static testing machine is produced according to the dynamic servo test technology. Our design of the electro-hydraulic servo testing system is unitized, standardized and modularized, which enhance the stability and reliability of the system. The electro-hydraulic servo testing system is mainly used to test the dynamic and static mechanical performance of material parts. Equipped with corresponding accessories, the servo-hydraulic testing system can do tensile, compression, low and high cycle, crack growth tests and other mechanical tests for various kinds of materials. The Dynamic and Static Testing Machine is widely used in the fields of aviation and aerospace, ship-building and military industries.
