Overview
The Qinsun QJWE-600KN Hydraulic Universal Testing Machine is a high-capacity, microprocessor-controlled electro-hydraulic servo system engineered for precision mechanical property evaluation of metallic and non-metallic materials under standardized uniaxial loading conditions. It operates on the principle of closed-loop hydraulic force control, utilizing proportional servo valves and high-stiffness load frames to maintain accurate load application across tension, compression, bending, and shear configurations. Designed in accordance with ISO 7500-1 (Class 1), ASTM E4, and GB/T 228.1–2021, this machine delivers traceable force measurement with ±1% accuracy over its full 0–1000 kN range, making it suitable for quality control laboratories, metallurgical R&D centers, and third-party certification facilities requiring compliance with GLP and ISO/IEC 17025 documentation protocols.
Key Features
- Oil-below-cylinder configuration with adjustable test space—enabling flexible specimen handling for long or bulky samples.
- Full-digital electro-hydraulic servo control system with programmable loading rates (0.005–100 mm/min) and multi-step stress/strain control modes (e.g., constant rate of loading, constant crosshead speed, or load hold).
- Imported high-precision load cell (calibrated to ISO 376 Class 0.5) and linear variable differential transformer (LVDT)-based displacement transducers ensure synchronized acquisition of force, extension, and deflection data.
- Robust cast-iron frame with reinforced column structure and preloaded ball-screw-driven crosshead positioning for minimal frame compliance and high axial rigidity.
- Dual-clamp design accommodating both round specimens (φ20–70 mm) and flat specimens (up to 40 mm thickness), with wedge-type self-tightening jaws and hydraulic actuation for consistent gripping pressure.
- Integrated safety interlocks—including overload protection, emergency stop circuitry, and automatic pressure relief—meeting CE machinery directive requirements (2006/42/EC).
Sample Compatibility & Compliance
The QJWE-600KN supports standardized test geometries per ASTM E8/E8M (tension), ASTM C39/C39M (concrete compression), ASTM D790 (flexural strength), and ISO 6892-1 (metal tensile testing). Its modular fixture interface allows rapid reconfiguration for tensile bars, cylindrical concrete cores, notched beams, or shear punch specimens. All force measurements are traceably calibrated using NIST-traceable deadweight standards, and system verification follows ISO 7500-1 procedures. The machine is compatible with accredited calibration services and supports audit-ready documentation for FDA 21 CFR Part 11–compliant environments when paired with validated software.
Software & Data Management
Control and analysis are performed via Qinsun’s proprietary TestMaster™ software, a Windows-based platform supporting real-time curve plotting (load vs. displacement, stress vs. strain), automatic yield point detection (0.2% offset method), modulus calculation (tangent/secant), and fracture energy integration. Data export formats include CSV, Excel, PDF, and XML for LIMS integration. Audit trails record user actions, parameter changes, and calibration events with timestamps and operator IDs. Software validation packages—including IQ/OQ documentation—are available upon request to support GMP/GLP implementation.
Applications
- Mechanical characterization of structural steels, aluminum alloys, titanium grades, and high-strength fasteners per EN 10002-1 and ASTM A370.
- Compressive strength assessment of cementitious composites, refractory bricks, and geopolymer mortars.
- Bending performance evaluation of reinforced polymer composites and laminated timber per ISO 14125.
- Shear strength determination of welded joints and riveted assemblies in aerospace and rail manufacturing.
- Validation of material behavior under simulated service loads for ASME BPVC Section II and API RP 2A-WSD compliance testing.
FAQ
What standards does the QJWE-600KN comply with for force measurement accuracy?
It meets ISO 7500-1 Class 1 requirements for static force verification, with verified linearity, hysteresis, and repeatability within ±1% of full scale.
Can the system be integrated into an existing laboratory network for centralized data management?
Yes—it supports TCP/IP communication, OPC UA protocol, and direct SQL database logging for enterprise-level data aggregation.
Is third-party calibration and certification available?
Qinsun partners with ISO/IEC 17025-accredited calibration laboratories; factory-certified calibration certificates with uncertainty budgets are provided with each unit.
What maintenance intervals are recommended for hydraulic system integrity?
Hydraulic oil filtration and replacement every 2,000 operating hours or biannually, plus annual verification of servo valve response and load cell drift.
Does the machine support automated test sequence programming for batch testing?
Yes—TestMaster™ enables script-based test templates with conditional logic, pass/fail criteria, and auto-generated reports per specimen ID or lot number.
