GBPI GBH-1Z Single-Column Electronic Tensile Testing Machine

Overview

The GBPI GBH-1Z Single-Column Electronic Tensile Testing Machine is a precision-engineered mechanical testing system designed for static tensile, peel, tear, puncture, compression, flexural, and shear characterization of thin, flexible materials. It operates on the principle of controlled uniaxial force application via a high-rigidity dual-column frame and precision ball-screw actuation, coupled with real-time load and displacement transduction using calibrated load cells and optical encoder-based position feedback. The instrument is optimized for routine quality control in packaging, polymer film, medical device, and pharmaceutical packaging manufacturing environments—where reproducible measurement of mechanical integrity under standardized test conditions is mandated by regulatory and industry specifications.

Key Features

• Class 0.5 force accuracy (±0.5% of reading) and displacement resolution compliant with ISO 7500-1 and ASTM E4 verification protocols.
• Dual-mode control architecture: supports both embedded standalone operation (with integrated controller and LCD interface) and PC-based operation via RS232 serial communication.
• High-speed data acquisition at 100 Hz sampling rate ensures fidelity in dynamic event capture—including yield point, break elongation, and modulus transitions.
• Modular sensor support: multiple analog input channels enable simultaneous or sequential integration of auxiliary transducers (e.g., extensometers, environmental chambers).
• Imported AC servo motor and precision preloaded ball screw drive deliver smooth, backlash-free motion across the full speed range (0–500 mm/min), minimizing inertial error during rapid load ramping.
• Robust safety architecture includes hardware-limit switches, software-defined overload cutoff, emergency stop circuitry, and automatic crosshead halt upon specimen rupture detection.
• Configurable test parameters: gauge length (adjustable), preload threshold, break criteria (force drop %, displacement limit), and dwell time—all programmable per test method.
• Optional pneumatic clamping system (available as add-on) ensures uniform stress distribution and eliminates slippage for low-modulus films and coated substrates.

Sample Compatibility & Compliance

The GBH-1Z accommodates specimens up to 50 mm wide and 750 mm effective travel length, making it suitable for standard and non-standard geometries defined in ASTM D828 (tensile properties of paper), ASTM F88 (seal strength of flexible barrier materials), ASTM D3330 (peel adhesion), and ISO 37 (vulcanized rubber). Its validated performance meets the metrological requirements of JJG 139 (national verification regulation for universal testing machines) and supports GLP-compliant audit trails when operated with optional FDA 21 CFR Part 11–enabled software modules. All mechanical and electrical subsystems conform to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards.

Software & Data Management

The included Windows-compatible software provides full method scripting, real-time curve overlay (up to 16 traces), statistical batch reporting (mean, SD, CV%, min/max), and automated pass/fail evaluation against user-defined specification limits. Raw data export is natively supported in CSV and Excel (.xlsx) formats; metadata—including operator ID, timestamp, environmental conditions (if logged), and calibration certificate traceability—is embedded in each dataset. The software architecture supports configurable electronic signatures and audit-log generation for GMP-aligned laboratories. Optional upgrade paths include networked multi-instrument monitoring and LIMS integration via OPC UA or HL7 interfaces.

Applications

• Quantitative assessment of seal strength (ASTM F88, YBB00112003) for blister packs, pouches, and sachets.
• Tensile modulus, yield stress, and ultimate elongation determination per GB/T 1040.3 and ISO 527-3 for polyolefin and polyester films.
• Peel resistance of pressure-sensitive adhesives (ASTM D3330) and laminated structures (GB/T 2790).
• Tear propagation resistance (ASTM D1938, GB/T 2791) in oriented polypropylene and metallized PET.
• Puncture force evaluation of medical packaging (YBB00202004) and protective gloves (GB 10808).
• Educational use in materials science curricula for hands-on demonstration of stress-strain behavior and Hooke’s law validation.

FAQ

What is the maximum allowable specimen thickness for the standard mechanical grips?
Standard manual wedge grips accommodate specimens up to 2.5 mm thick; thicker or rigid samples require custom jaw inserts or optional pneumatic clamps.
Can the GBH-1Z be calibrated to ISO/IEC 17025 accredited laboratories?
Yes—GBPI provides NIST-traceable calibration certificates; users may engage third-party ISO/IEC 17025-accredited providers for periodic verification per JJG 139 schedule.
Is thermal environmental control supported?
The base configuration does not include temperature chambers; however, the open data architecture allows integration with external environmental chambers via analog/digital I/O triggers and synchronized data logging.
Does the system support ASTM E4-compliant force verification procedures?
Yes—the load cell linearity, hysteresis, and repeatability are verified annually per ASTM E4 Annex A1 using certified deadweight standards.
What is the warranty coverage and service response time?
GBPI offers a 24-month limited warranty covering parts and labor; technical support is available via remote diagnostics, and field service dispatch is scheduled within 5 business days for critical issues in mainland China.
