Hengyi HY-0230 Universal Testing Machine

Overview

The Hengyi HY-0230 Universal Testing Machine is an electromechanical static testing system engineered for precision mechanical property evaluation of metallic, polymeric, composite, and elastomeric materials under uniaxial loading conditions. It operates on the principle of servo-controlled electromechanical actuation, delivering highly repeatable force application and displacement tracking across tension, compression, bending, peel, puncture, and shear configurations. Designed for laboratory environments in quality control, R&D, and academic settings, the HY-0230 complies with fundamental mechanical test architecture requirements defined in ISO 6892-1 (tensile testing of metals), ASTM E4 (load verification), ASTM D638/D790 (plastics tensile/flexural), and ISO 527/178 (polymer mechanical characterization). Its modular load frame, integrated high-resolution transduction chain, and real-time closed-loop control enable traceable, GLP-aligned data acquisition suitable for internal validation and regulatory documentation.

Key Features

• 0.5-class accuracy per ISO 7500-1, verified across full 0.2–100% of 2000 N capacity with uniform resolution (±500,000 counts, no range switching)
• High-fidelity 32-bit ARM9 microcontroller paired with military-grade 24-bit analog-to-digital conversion for noise-immune signal conditioning
• Optically isolated USB 2.0 interface supporting hot-plug operation, 56 MIPS processing throughput, and deterministic latency for synchronized multi-channel acquisition
• Programmable dual-speed crosshead actuation (fast jog + fine positioning) with electronic end-stop protection and automatic return-to-origin functionality
• Multi-mode closed-loop control: force-rate, displacement-rate, strain-rate, and hold-based protocols (constant load, constant displacement, constant strain)
• Real-time dynamic display of load–displacement–time curves on integrated LCD; simultaneous streaming to host PC via proprietary software suite
• Rugged extruded aluminum enclosure with industrial-grade powder coating; compact footprint (430 × 315 × 855 mm) optimized for benchtop integration
• Comprehensive safety architecture including 110% overload cutoff, thermal overcurrent monitoring, and autonomous system diagnostics at power-on and runtime

Sample Compatibility & Compliance

The HY-0230 accommodates standardized specimens per ISO, ASTM, DIN, and GB geometries—including dog-bone tensile bars (ISO 527–2, ASTM D638), flexural beams (ISO 178, ASTM D790), peel coupons (ASTM D903), and puncture fixtures (ASTM F1306). Its 120 mm effective test width and 300 mm vertical stroke support both rigid and compliant materials, from thin films (<0.1 mm) to structural composites (≤25 mm thick). All measurement algorithms and reporting outputs are structured to satisfy audit-ready documentation requirements under ISO/IEC 17025, FDA 21 CFR Part 11 (with optional electronic signature module), and GMP/GLP environments. Calibration certificates traceable to national metrology institutes (e.g., NIM China, NIST USA) are available upon request.

Software & Data Management

The HY-0230 ships with Hengyi’s proprietary Windows-based testing software—validated for Windows 10/11 64-bit platforms. The application supports fully customizable test methods, multi-step ramp-hold sequences, real-time curve overlay, and automated parameter extraction (UTS, yield strength, modulus, elongation at break, secant modulus, bending stiffness, etc.). Raw data exports in CSV, Excel, and XML formats preserve timestamped channel metadata (force, displacement, strain, time). Audit trail logging records all user actions, method changes, calibration events, and system errors. Optional PDF report generation includes header metadata (operator ID, sample ID, environmental conditions), statistical summaries, and embedded stress–strain plots compliant with ISO 14289-1 (PDF/A-2u).

Applications

• Mechanical qualification of engineering thermoplastics (PP, ABS, PC, PEEK) and elastomers (silicone, TPU, NR)
• Adhesion strength assessment of laminated packaging, medical device bonding, and automotive trim interfaces
• Stiffness and failure analysis of biomedical polymers (sutures, catheter tubing, orthopedic fixation devices)
• Quality conformance testing of fasteners, springs, and stamped metal components per ISO 898 or GB/T 3098
• Research-scale fatigue pre-screening using low-cycle protocols (1–100 cycles) with programmable dwell and reversal logic
• Educational demonstration of Hooke’s law, plastic deformation, necking behavior, and fracture mechanics fundamentals

FAQ

What international standards does the HY-0230 support out-of-the-box?

The system includes preloaded test templates for ISO 6892-1, ASTM D638, ASTM D790, ISO 527, ISO 178, and GB/T 1040 — with full configurability for custom standard implementation.
Is the force sensor calibrated and traceable?

Yes — each unit ships with a factory calibration certificate traceable to China’s National Institute of Metrology (NIM); third-party recalibration services with NIST-traceable documentation are available.
Can the HY-0230 operate without a PC connection?

Yes — standalone mode enables basic tension/compression tests with real-time LCD display, manual parameter entry, and local result storage (up to 100 test records).
What maintenance is required for long-term accuracy?

Annual verification of load cell linearity, crosshead alignment, and encoder resolution is recommended; no routine lubrication or mechanical adjustment is needed due to brushless DC motor and preloaded ball-screw design.
Does the software support multi-user access control and audit trails?

Yes — role-based login (administrator/operator), tamper-proof event logging, and electronic signature workflows meet 21 CFR Part 11 Annex 11 requirements when configured with optional security module.
