Introduction
WAW- E Servo Hydraulic Tensile Testing Machine is mainly used for tensile test wit high efficiency requirement. Equipped with relevant fixtures, this machine can also be used for compression, bending and shearing tests. Constant strain, Constant stress and constant displacement test are available. Strain velocity, stress velocity and displacement velocity conform to the requirement of GB, ASTM, DIN, ISO, JIS, BS etc. metal tensile testing standards.
It is an ideal equipment for tensile test of metal rod, board, screw, steel strand (with special fixture) etc. material with high stiffness. Four coloumns structure,long travel double-action oil cylinder with high accuracy & close sealing to meet the requirement of different specimen lengths or specimen with high elongation.
High stiffness load frame with low gravity center. Impact with specimen broken was released by hydraulic unit to decrease the noise and vibration maximally. Upper oil cylinder design with down-setting tensile space makes the operation very easy.
GTM (Germany) Double-Flange double direction load cell with high linearity to ensure the high accuracy of test result.
Adopts high accuracy of advanced horizontal pushing clamping grip. Non-step in full testing range.
High quality hydraulic components to avoid the leakage and protect testing environment. MOOG (USA) servo Valve ensures high response speed and high control accuracy.
