300 kN MATERIALS TESTING EQUIPMENT

Controlled Tensile, Compression and Bending Testing

The WAW-300D electro-hydraulic servo universal testing machine combines hydraulic loading, digital closed-loop control, real-time data acquisition, curve visualization and result processing in one test platform. Supplied by Laizhou Jincheng Industrial Equipment Co., Ltd., it is designed for laboratories, production quality departments and research organizations that require repeatable mechanical-property testing of metallic and non-metallic materials.

Its lower-cylinder, six-column frame works with a 300 kN load sensor, extensometer, displacement sensor and dedicated PC software. The system controls test force, piston displacement or specimen deformation, helping operators standardize loading procedures and reduce manual data recording during tensile, compression and bending tests.

Multiple Test Modes

Performs room-temperature metal tensile tests and compression or bending tests on suitable metallic and non-metallic specimens. Modulus and Poisson’s ratio testing can be configured according to the applicable method.

Closed-Loop Servo Control

Digital PID control supports constant-rate force, piston displacement and strain modes. Control modes can transition smoothly during a procedure to match different test stages.

Automated Data Processing

Software records force, deformation, displacement and loading rate, generates test curves, exports ASCII data and prepares individual or batch reports. Tensile parameters may include Fm, Rel, Reh, Rp, Rt, Agt, Z, A and Rm.

Hydraulic Gripping and Protection

A separate low-noise hydraulic source controls specimen gripping. Overload, over-limit, power-loss and piston travel protections support safer operation and help protect the machine and specimen.

Technical Parameters, Configuration and Application Fit

WAW-300D is suited to users requiring 300 kN loading capacity, computer-controlled testing and traceable result management. Key specifications should be reviewed together with specimen geometry, gripping requirements, test standards, laboratory space and local power conditions.

Standard System Composition

The system includes the hydraulic test frame, servo oil source and valve, digital PC controller, measuring sensors, extensometer, computer, printer, control software, electrical cabinet and standard tensile, compression and bending fixtures.

Typical Users and Tasks

Suitable for incoming inspection, process control, final product verification, material selection, batch comparison, research and engineering education in metallurgy, machinery, construction, aerospace and materials development.

Standards and Customization

Testing may be configured with reference to relevant GB/T material and testing-machine standards. Special fixtures, non-standard specimens or online testing requirements should be evaluated by Laizhou Jincheng against the required loading method and reporting procedure.

Selection note: Final configuration should be confirmed according to material type, specimen dimensions, applicable regional standards and installation conditions. With stable servo loading and integrated test-data management, the WAW-300D supports more consistent material evaluation while preserving test records for review and quality documentation.
