WAW-300D 300kN Electro-Hydraulic Servo Universal Testing Machine

The WAW-300D is a 300kN universal testing machine for tensile, compression and bending tests of steel, metal products and mechanical components. It combines hydraulic loading, digital closed-loop control, real-time curve display and automated result processing in one inspection platform.

Supplied by Laizhou Jincheng Industrial Equipment Co., Ltd, the system supports incoming material inspection, in-process checks and final quality evaluation where repeatable loading control and traceable test records are required.

What the system measures and controls

Force, displacement and deformation: monitors the material response throughout the test process.
Closed-loop loading: supports constant test force, piston displacement and strain rate control.
Automatic data processing: records curves, saves test data and generates result reports for review.
Hydraulic gripping: accommodates round and flat specimens with dedicated tensile, compression and bending fixtures.

Test capability, configuration and quality-control value

For material laboratories and manufacturing quality departments, the WAW-300D helps standardize how mechanical properties are tested, displayed and retained. During metal tensile testing, the software can calculate parameters including Fm, Rel, Reh, Rp, Rt, Agt, Z, A and Rm; personnel can review applicable results before reporting.

Incoming inspection

Verify batch mechanical properties before steel or metal materials enter production.

Process verification

Compare property changes after forming, heat treatment or process adjustment.

Final quality evaluation

Retain curves and test records to support product release and internal traceability.
