YANRUN WEW-300B Computer-Controlled Hydraulic Universal Testing Machine

Overview

The YANRUN WEW-300B is a computer-controlled hydraulic universal testing machine engineered for high-reliability mechanical property evaluation of metallic, polymeric, composite, and ceramic materials under tension, compression, bending, and shear loading conditions. Built on a robust lower-mounted hydraulic architecture, the system delivers exceptional structural stability and operational safety while minimizing floor-space requirements and installation complexity. Its dual-cylinder hydraulic actuation system—comprising a high-precision servo-controlled oil pump and a synchronized crosshead drive—ensures smooth force application, low hysteresis, and high reproducibility across load cycles. The machine complies with core mechanical testing standards including ASTM E4, ASTM E8/E8M, ISO 6892-1, ISO 37, and GB/T 228.1, supporting both static monotonic and stepwise quasi-static test protocols. Designed for integration into QC laboratories, R&D centers, and accredited testing facilities, the WEW-300B serves as a foundational platform for material qualification, process validation, and regulatory documentation in industries ranging from aerospace component manufacturing to civil infrastructure materials certification.

Key Features

• Lower-mounted hydraulic mainframe design: Reduces overall height (1950 mm) and center of gravity, enhancing rigidity and operator accessibility without compromising maximum 300 kN capacity.
• Computer-integrated control architecture: Real-time Windows-based software enables closed-loop PID control of load, displacement, and strain—fully programmable via customizable test steps and multi-stage ramp/hold profiles.
• Open-architecture test configuration: Users may create, edit, import, and export test methods, standard templates (e.g., ASTM D638, ISO 527), and procedural sequences using native XML or CSV formats.
• Excel-native reporting engine: Generates fully user-definable reports—including multi-specimen consolidation, dynamic field selection, and custom calculation fields—without proprietary viewer dependencies.
• Dual-tier user permission system: Enforces role-based access control (Administrator / Tester) with audit-trail logging for GLP/GMP-aligned environments requiring traceable operator actions.
• Triple-layer hardware safety interlocks: Includes over-load protection (shutdown at >103% of full-scale load), upper-limits piston travel cutoff, and emergency hydraulic pressure dump circuitry compliant with ISO 13850.
• Modular fixture compatibility: Supports rapid interchange of tensile jaws (round: Φ6–Φ26 mm; flat: 0–15 mm × 75 mm width), compression platens (φ160 mm standard; 204×204 mm optional), and three-point bending fixtures (span up to 450 mm, roller Φ30 mm).

Sample Compatibility & Compliance

The WEW-300B accommodates standardized and non-standard specimens per ISO 527-2, ASTM E8, ASTM D695, and GB/T 228.1 geometries. Round specimens from Φ6 mm to Φ26 mm and flat specimens up to 15 mm thick × 75 mm wide are clamped hydraulically with self-aligning jaw faces to minimize bending moments. Compression testing utilizes hardened steel platens meeting ASTM E10 requirements for hardness and parallelism. Bending tests follow ISO 178 specifications with adjustable support spacing (up to 450 mm) and precision-ground rollers. All mechanical measurements—including force (0.01 kN resolution), displacement (0.01 mm), and deformation (0.01 mm)—are traceable to national metrological standards. System-level compliance includes CE marking (2006/42/EC Machinery Directive), ISO/IEC 17025 readiness for calibration verification, and alignment with FDA 21 CFR Part 11 requirements for electronic records when paired with validated software configurations.

Software & Data Management

The embedded Windows 10–based control software provides real-time graphical monitoring of load-displacement, stress-strain, and time-history curves with configurable sampling rates up to 100 Hz. All raw data—including analog sensor inputs, control setpoints, and system status flags—are stored in open binary + CSV dual-format archives with embedded metadata (operator ID, timestamp, environmental conditions, calibration certificate IDs). Export functions support direct integration with LIMS platforms via ODBC and RESTful API endpoints. Audit trails record every parameter change, test initiation, result modification, or user login event—retained for ≥36 months with immutable hashing. Software validation documentation (IQ/OQ/PQ protocols) and electronic signature workflows are available upon request for regulated environments.

Applications

• Mechanical characterization of structural steels, aluminum alloys, and titanium grades per ASTM A370 and EN 10002-1.
• Quality conformance testing of welded joints, castings, and forged components in energy and transportation sectors.
• Validation of polymer composites (CFRP/GFRP) for automotive crashworthiness and aerospace primary structures.
• Compression strength assessment of concrete cylinders, mortar prisms, and geotechnical specimens per ASTM C39 and ISO 7500-1.
• Bending modulus and flexural strength determination of thermoplastics, elastomers, and fiber-reinforced laminates per ISO 178 and ASTM D790.
• Calibration reference testing for secondary force standards in metrology labs accredited to ISO/IEC 17025.

FAQ

What standards does the WEW-300B comply with for force measurement accuracy?
It meets ISO 7500-1 Class 1 and ASTM E4 requirements for verified force systems, with certified accuracy of ±0.5% of reading within 20–100% of full scale.
Can the system perform closed-loop strain-controlled testing?
Yes—when equipped with an extensometer interface module and compatible clip-on or video-based extensometers, it supports displacement- and strain-controlled modes per ASTM E8 and ISO 6892-1.
Is remote diagnostics and firmware update supported?
The control cabinet includes Ethernet and RS-232 ports; remote maintenance is enabled via secure VPN-tunneled TeamViewer sessions under signed service agreement.
What is the recommended calibration interval?
Annual recalibration is advised; however, interval adjustments may be justified per ISO/IEC 17025 risk-based assessment or internal quality procedures.
Does the software support multi-language UI and report generation?
English and Simplified Chinese interfaces are standard; report templates can be localized using embedded Unicode-compliant font sets and regional number/date formatting.
