Shandong Huayan WAW series microcomputer controlled electro-hydraulic servo universal testing machine is mainly used for tensile, compression, bending and other mechanical properties testing of metal materials, such as various steel bars, metal plates, bars, castings, forgings, cables and ropes, bolt fasteners, etc. The force value can reach 2000KN.The computer fully-automatic closed-loop controls the high-performance electro-hydraulic servo valve to complete tension, compression, bending and other tests on metal materials. It can automatically obtain experimental results such as FM, REH, REL, RPO.2, RP1, RM and elastic modulus E of the material, meeting the requirements of the new standard GB/T228.1-2021 "Room Temperature Tensile Test Method for Metal Materials".

This series of models is divided into two-column and four-column models, both of which are composed of a high-strength main engine with a lower oil cylinder and a piano-type oil source control cabinet. It adopts microcomputer servo control and combines advanced hydraulic control technology to implement standardized unit design. It can accurately measure the tensile strength, yield strength, and regulations of metal materials.Mechanical properties such as proportional elongation strength, elongation, and elastic modulus meet the requirements of the new standard GB/T228-2021 "Metallic Materials Tensile Test Method at Room Temperature". It has the characteristics of high measurement accuracy, ultra-quiet, energy-saving, flexible configuration, easy accessory interchange, and easy after-sales service.
