Overview
The Qingji QJ210A-5KN Universal Testing Machine is an electromechanical force-testing system engineered for precise tensile, peel, tear, shear, and puncture characterization of polyethylene (PE) films, foils, laminates, and related polymer-based materials—particularly suited for quality control of copper-clad laminates (CCL) and printed circuit board (PCB) copper foils. Operating on the principle of controlled uniaxial loading via a high-resolution servo-driven crosshead, the system applies calibrated mechanical force while synchronously measuring load, displacement, and strain in real time. Its modular design enables rapid reconfiguration between standardized test modes without hardware recalibration, supporting both R&D validation and routine production-line verification under regulated environments.
Key Features
- High-fidelity force measurement using U.S.-sourced precision load cells with 500,000-count resolution and no internal range switching—ensuring consistent sensitivity across the full 0–5000 N span.
- Japanese Panasonic all-digital AC servo control system delivering stable, low-noise actuation with programmable speed profiles from 0.01 to 500 mm/min (±0.5% speed accuracy).
- Dual-speed manual/electric crosshead adjustment with integrated software diagnostics and electronic limit protection to prevent overtravel or overload damage.
- Full-range displacement sensing with ±0.5% accuracy and automatic return-to-start functionality post-test—reducing operator intervention and improving throughput.
- Overload protection threshold set at 110% of full scale, coupled with real-time software fault detection for GLP-compliant operation.
- Industrial-grade enclosure featuring extruded aluminum panels and electrostatic powder coating for long-term durability and ESD-safe laboratory integration.
Sample Compatibility & Compliance
The QJ210A-5KN accommodates flat, flexible, and semi-rigid specimens up to 150 mm wide and 800 mm in effective travel length—including PE films, LDPE/HDPE sheets, metallized polymer substrates, adhesive tapes, and PCB copper foils. Customizable fixture sets (e.g., pneumatic wedge grips, peel arms, trouser-tear jigs, and puncture probes) allow seamless transition between ASTM D882 (tensile properties of thin plastic sheeting), ISO 527-3 (plastics—determination of tensile properties), GB/T 1040.3 (Chinese national standard for plastics tensile testing), JIS K7127, and YY/T 0148 (medical packaging peel strength). The system supports audit-ready data integrity per FDA 21 CFR Part 11 when paired with compliant software—enabling electronic signatures, user access controls, and immutable audit trails.
Software & Data Management
Control and analysis are executed via Qingji’s proprietary Windows-based testing software, compatible with Windows 10/11 and requiring no third-party runtime dependencies. The interface provides real-time graphical display of stress–strain curves, load–displacement plots, and time-series parameter tracking. Users may define multi-step test protocols—including preload hold, ramp-to-break, and cyclic loading—with automated calculation of modulus, yield strength, elongation at break, peel adhesion energy (N/mm), and tear resistance (kN/m). Raw data exports to CSV, Excel, or PDF report formats; optional integration with LIMS or MES systems is supported via TCP/IP or RS232 communication. All software logs include timestamped operator ID, environmental metadata (if external sensors are connected), and instrument calibration status.
Applications
- Tensile property evaluation of virgin and recycled PE films used in food packaging, agricultural mulch, and geomembranes.
- Peel strength assessment of pressure-sensitive adhesives bonded to PE carriers per ASTM D903 or ISO 8510-2.
- Tear propagation resistance testing of HDPE geomembranes per GRI-GM13 protocols.
- Shear adhesion failure analysis of laminated PE/aluminum structures in flexible electronics substrates.
- Puncture resistance quantification of PE-based medical device packaging per ISO 11607-2.
- Quality conformance verification for copper foil lamination integrity on FR-4 substrates in PCB manufacturing.
FAQ
Does the QJ210A-5KN comply with ISO/IEC 17025 requirements for accredited testing laboratories?
Yes—when operated with documented calibration certificates traceable to NIST or CNAS-accredited standards, and with validated software configuration, the system meets metrological prerequisites for ISO/IEC 17025 clause 6.4 and 6.6.
Can the machine perform constant-rate-of-traverse (CRT) and constant-rate-of-loading (CRL) tests?
It supports CRT mode natively; CRL requires closed-loop load feedback enabled via optional firmware upgrade and sensor recalibration.
Is remote monitoring or networked fleet management supported?
Standard Ethernet connectivity allows remote status polling and basic job queuing; advanced SCADA-level integration requires Qingji’s OEM API toolkit and site-specific validation.
What maintenance intervals are recommended for sustained accuracy?
Load cell and encoder verification every 12 months; servo drive inspection and lubrication of lead screws every 24 months; full system calibration advised after any mechanical impact or relocation.
Are fixtures and accessories supplied with traceable calibration documentation?
Standard grips ship with factory-as-tested reports; custom fixtures may be provided with individual calibration certificates upon request—subject to additional lead time and cost.
