WEW Series machine, is adopting oil hydraulic power to push the piston in the oil cylinder to provide loading force. So it is very suitable for tension, compression, bending and shearing strength test for various metal or nonmetal materials under high toughness and hardness against extreme big loading force. By using oil pressure transducer and photoelectric encoder, computer can timely collect the testing parameters like loading force, stroke etc. This machine is adopting manual control mode and computer collecting and displaying methods to process the testing parameters. The software based on Windows system is able to make automatic calculating of test results, i.e. tensile strength, up / low yield strength, Non proportional stress point, Modulus of Elasticity etc. This machine is widely used in different inspection department, engineering area, laboratories, universities and institutes for material properties research and quality control. These machines can meet standards ASTM, DIN, ISO, GBand so on.
