Controlled Mechanical Testing for Research and Laboratory Teaching

The WAW-300D is a computer-controlled electro-hydraulic servo universal testing machine with a maximum test force of 300 kN. It performs tensile, compression and bending tests for metal materials, and can support compression and other static uniaxial tests for non-metal materials when matched with suitable methods and fixtures. Laizhou Jincheng Industrial Equipment Co., Ltd. integrates hydraulic loading, digital control, real-time acquisition and result processing in one laboratory-grade system.

Why closed-loop testing matters

Controlled loading: Force, piston displacement and specimen deformation can be controlled through electro-hydraulic feedback.
Visible test process: Live force, displacement, rate and deformation data help users observe material response during loading.
Traceable research records: Curves, raw data and reports can be saved for batch comparison, method verification and teaching documentation.

Test Functions, Data Processing and Laboratory Fit

WAW-300D is designed for universities, research institutes and corporate material R&D centers that need more than a single strength value. Its PC measurement and control system supports constant-rate force, piston displacement and strain control modes, allowing the loading program to be adjusted to the selected material and test method.

Tensile, Compression and Bending

Standard equipment includes round and flat tensile jaws, 160 × 160 mm compression fixtures, and bending fixtures with a 30 mm indenter and 0–450 mm span. Hydraulic clamping supports round specimens from Φ6–Φ26 mm and flat specimens within the stated jaw capacity.

Curves and Result Analysis

The software displays force-time, deformation-time and force-deformation curves in real time. Users can zoom or capture curve sections, review values with cursor tracking, export ASCII data, and create single-specimen or batch reports. Metal tensile calculations can include Fm, Rel, Reh, Rp, Agt, Z, A and Rm where applicable.

Configuration and Installation Review

Fixture selection should be confirmed against specimen geometry, dimensions, loading method and applicable standards. With an approximate weight of 2200 kg and AC 380 V power requirement, the installation site should also be checked for floor capacity, access route, grounding, operating space and environmental conditions.

Suitable for material research and structured teaching: WAW-300D provides an adjustable, documented testing platform for performance evaluation, process-state comparison, laboratory instruction and test-method validation. Laizhou Jincheng can help users confirm fixture, software and configuration suitability based on their specimen types, test items and laboratory conditions.
