Overview
The Hengyi HY-0580HJKN is a precision-engineered single-arm electromechanical universal testing machine specifically optimized for mechanical characterization of low-force, high-ductility organic polymer thin films—including polyimide (PI), polyethylene terephthalate (PET), polylactic acid (PLA), polyvinylidene fluoride (PVDF), and multilayer barrier films used in flexible electronics, packaging, and biomedical substrates. It operates on the fundamental principle of controlled uniaxial force application via a servo-controlled ball-screw actuator, with real-time acquisition of tensile load, axial displacement, and optional extensometric strain. The system adheres to static single-axis testing architecture defined in ISO 7500-1 and ASTM E4, ensuring metrological traceability and repeatability required for R&D validation and quality control in regulated environments.
Key Features
- Modular load cell architecture supporting interchangeable transducers from 1 N to 5000 N — enabling seamless transition between ultra-thin film (e.g., <5 µm PET) and reinforced composite laminates without recalibration.
- High-resolution force measurement system with ±500,000-count A/D conversion and no internal range switching — maintaining full-scale resolution across the entire dynamic range (0.1% to 100% FS).
- Precise speed control from 0.001 mm/min (creep-sensitive quasi-static loading) to 500 mm/min (high-rate delamination or tear propagation), with closed-loop feedback ensuring ±0.5% speed accuracy per ISO 5893.
- Dual-mode motion control: manual jog for rapid specimen alignment and programmable automated sequences for standardized test protocols (e.g., ISO 527-3 Annex B for film clamping procedures).
- Integrated electronic limit switches and hardware-based overload cutoff (110% FS threshold) — eliminating reliance solely on software interlocks for operator and equipment safety.
- Self-diagnostic subsystem continuously monitors drive current, encoder integrity, amplifier voltage, and thermal load — logging anomalies and initiating protective shutdown prior to component stress accumulation.
Sample Compatibility & Compliance
The HY-0580HJKN accommodates specimens up to 120 mm wide and 800 mm gauge length, compatible with standard film grips (pneumatic, serrated, or rubber-faced), peel fixtures, and custom micro-clamps for sub-5 mm width samples. Its mechanical design satisfies GB/T 2611-2007 (General Technical Requirements for Testing Machines), GB/T 16491-2008 (Electronic Universal Testing Machines), and GB/T 16852.1-2008 (Verification of Static Uniaxial Testing Machines). Software-configurable test methods align with ISO 527-3 (Plastics – Determination of Tensile Properties – Part 3: Films and Sheets), ASTM D882 (Tensile Properties of Thin Plastic Sheeting), ASTM D3759 (Tensile Properties of Tape), and JIS K7127 (Tensile Testing of Plastics). Calibration certificates are traceable to national metrology institutes (NIM, China) and support GLP-compliant audit trails when paired with validated firmware.
Software & Data Management
The embedded Windows-based control software provides ISO/IEC 17025-aligned test definition workflows, including multi-step ramp-hold-relax cycles, modulus calculation via secant/tangent methods, and automatic yield point detection per ASTM D638. All raw data (force, displacement, time, calculated stress/strain) are stored in ASCII-compatible .csv format with metadata headers (operator ID, calibration date, environmental conditions). Audit logging meets FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with user role management and digital certificate authentication. Optional API integration enables direct data ingestion into LIMS platforms (e.g., LabWare, Thermo Fisher SampleManager) or MATLAB/Simulink for advanced viscoelastic modeling.
Applications
- Quantification of tensile strength, elongation at break, Young’s modulus, and Poisson’s ratio for roll-to-roll coated polymer films used in OLED encapsulation and lithium-ion battery separators.
- Evaluation of adhesion strength in pressure-sensitive adhesive (PSA) tapes via 90° and 180° peel tests per ASTM D3330 and PSTC-101.
- Mechanical screening of biodegradable films (e.g., PHA, PCL blends) under controlled humidity and temperature (when integrated with environmental chamber).
- Validation of thermo-mechanical stability during accelerated aging studies (ISO 11607-1) for medical device packaging films.
- Interfacial shear strength assessment in multilayer co-extruded structures using micro-tensile specimens fabricated by focused ion beam (FIB).
FAQ
What is the minimum measurable force resolution for ultra-thin polymer films?
The system achieves effective force resolution down to 0.002 N (0.2 mN) when equipped with the 1 N load cell, supported by 24-bit ADC and noise-reduction filtering optimized for low-magnitude signal integrity.
Can the HY-0580HJKN be integrated with an environmental chamber?
Yes — the machine features standardized mounting interfaces and analog/digital I/O ports compliant with ASTM E145 for third-party chamber synchronization (temperature range: −70 °C to +250 °C; humidity: 10–95% RH non-condensing).
Does the software support automated pass/fail evaluation against specification limits?
Yes — users may define upper/lower tolerance bands per parameter (e.g., “Elongation ≥ 120% ±5%”) and generate PDF reports with color-coded compliance status, revision-controlled templates, and digital signature fields.
Is calibration documentation provided with NIST-traceable references?
Each unit ships with a factory calibration certificate referencing national standards (GB/T 16852.1), and optional on-site calibration services include uncertainty budgets per ISO/IEC 17025 and comparison against certified reference materials (CRMs) from NIM or PTB.
How is data integrity maintained during power interruption?
The controller employs non-volatile memory buffering — all active test data up to the last 5 seconds is preserved and recovered upon restart, preventing loss of critical failure-point measurements.
