Overview
The Hengyi HY-0580UIKKK is a high-precision electromechanical universal testing machine engineered for static mechanical characterization of soft and compliant materials—particularly hydrogels, silicone sealants, adhesives, thin films, biomedical polymers, and elastomeric composites. It operates on the principle of controlled uniaxial force application with real-time load, displacement, and strain feedback, enabling quantitative evaluation of tensile strength, compressive modulus, elongation at break, peel resistance, tear propagation, and time-dependent behaviors such as stress relaxation and creep. Designed to meet ISO 527, ASTM D638, ASTM D3039, ISO 37, ISO 1133, GB/T 228.1, and JIS K7113 standards, the system supports both open-loop speed control and closed-loop stress/strain rate regulation—critical for reproducible testing of viscoelastic biomaterials where loading history significantly influences mechanical response.
Key Features
- Modular load cell architecture supporting interchangeable transducers from 1 N to 5000 N, ensuring optimal resolution across low-force hydrogel deformation and higher-load silicone sealant rupture testing.
- 0.5-class accuracy certified per ISO 7500-1, with full-scale resolution of ±500,000 digital counts and no internal range switching—maintaining consistent sensitivity throughout the entire measurement span.
- Precise motion control with speed range of 0.001–500 mm/min and ±0.5% speed fidelity, enabling quasi-static tensile tests on fragile hydrogels and high-rate dynamic assessments of packaging films or medical tubing.
- Dual-mode actuation: manual clamping fixtures for routine hydrogel specimen handling and optional pneumatic grips for high-throughput, operator-independent gripping of silicone sealants and adhesive tapes.
- Integrated electronic limit protection, overload cutoff (110% FS), and self-diagnostic routines monitoring drive current, voltage, thermal load, and sensor integrity in real time.
- Motorized crosshead with dual-speed lift (fast/slow) and programmable return—reducing cycle time between specimens while preserving positional repeatability.
Sample Compatibility & Compliance
The HY-0580UIKKK accommodates diverse specimen geometries and mechanical classes—including hydrogels (e.g., PVA, alginate, HA-based networks), silicone elastomers (RTV, HTV), pressure-sensitive adhesives, thin metallic foils (Cu/Al), photovoltaic interconnect ribbons, suture materials, biodegradable sutures, foam matrices, pharmaceutical films, and laminated packaging substrates. Its 120 mm test width and 800 mm vertical travel support standardized dumbbell, dog-bone, strip, and film configurations per ASTM D882 and ISO 1183. All hardware and firmware comply with electromagnetic compatibility (EMC) directives (IEC 61326-1) and functional safety requirements for laboratory instrumentation. Data acquisition and reporting workflows are structured to support GLP-compliant documentation and audit-ready traceability when paired with validated software configurations.
Software & Data Management
HYtest v4.x software provides multi-axis real-time plotting (load vs. displacement, stress vs. strain, stress vs. time, strain vs. time), with overlay capability for up to eight curves using user-defined color schemes. The platform implements automatic feature detection—including yield point (Rp0.2), ultimate tensile strength (Rm), Young’s modulus (E), fracture energy, and plateau stress—and allows manual point annotation for comparative analysis across batches or formulations. Curve analysis tools support tangent modulus calculation, hysteresis loop integration, and relaxation/creep fitting using standard linear solid or Prony series models. Export options include CSV, PDF, and XML formats; raw data files retain full metadata (operator ID, timestamp, environmental conditions, calibration certificates). For regulated environments, optional 21 CFR Part 11 compliance modules provide electronic signatures, audit trails, and role-based access control.
Applications
- Mechanical qualification of wound dressings and tissue-engineered scaffolds under hydrated conditions.

- Quality control of construction-grade silicone sealants per ASTM C920 and GB/T 14683.
- Tensile fatigue and cyclic loading studies on hydrogel-based drug delivery matrices.
- Peel and tack testing of pressure-sensitive hydrogel electrodes used in wearable biosensors.
- Compression modulus mapping of soft robotics actuators and stimuli-responsive gels.
- Creep compliance and stress relaxation profiling for FDA-submitted polymer dossiers.
FAQ
What load cell options are available for hydrogel testing requiring sub-10N resolution?
Standard configurations include 1 N, 5 N, and 10 N load cells with ≥0.001 N resolution—optimized for low-modulus hydrogel deformation without signal saturation.
Can the system perform ASTM D412 rubber tensile tests on silicone elastomer sheets?
Yes—the machine supports die-cut dumbbell specimens (Type A/C), automatic gauge length recognition, and modulus calculation per ASTM D412 Annex A4.
Is third-party calibration certification included with delivery?
Each unit ships with an ISO/IEC 17025-accredited calibration certificate traceable to NIM (China National Institute of Metrology), valid for 12 months.
Does HYtest software support automated pass/fail decision logic against specification limits?
Yes—users can define acceptance criteria per parameter (e.g., Rm ≥ 0.8 MPa, Elongation ≥ 400%), triggering visual alerts and report flags upon deviation.
How is environmental control integrated during testing?
The base system does not include environmental chambers; however, it features RS-485 and analog I/O ports for seamless synchronization with external temperature/humidity chambers (e.g., ESPEC, Weiss) via custom script integration.
