Jianhu JH-50Kgf Single-Column Electromechanical Tensile Tester

Overview

The Jianhu JH-50Kgf Single-Column Electromechanical Tensile Tester is an entry-level universal testing instrument engineered for precision force measurement in static mechanical characterization of small-scale components and thin-section materials. Based on the fundamental principle of uniaxial tensile loading under controlled displacement rate, the system applies calibrated axial force via a high-stiffness load frame and AC servo-driven crosshead, enabling compliant yet repeatable evaluation of tensile strength, yield point, elongation at break, and load–displacement behavior. Designed specifically for laboratory and QC environments handling low-to-medium force applications—typically below 500 N (50 kgf)—this tester meets essential functional requirements for routine mechanical verification in electronics assembly, polymer component validation, rubber gasket qualification, and precision metal stamping. Its compact footprint and modular architecture support integration into constrained benchtop workspaces without compromising structural rigidity or thermal stability during extended test cycles.

Key Features

• Single-column rigid steel frame with vertical alignment tolerance ≤ ±0.05 mm/m, minimizing lateral deflection during load application
• AC servo motor drive with closed-loop position and speed control, delivering consistent velocity accuracy across the full 1–200 mm/min range
• Digital load cell with internal 20-bit A/D conversion and factory-calibrated traceability to national standards (NIM-certified calibration certificate available)
• Adjustable crosshead travel (150 mm stroke) with mechanical limit switches and software-defined soft stops for operator safety and specimen protection
• Integrated digital display console with real-time load, displacement, and test time readouts; supports manual start/stop and preset test protocols
• Benchtop form factor (300 × 300 × 1000 mm) optimized for ISO 17025-compliant lab layouts and GLP-aligned workflow documentation

Sample Compatibility & Compliance

The JH-50Kgf tester accommodates specimens up to 150 mm in gauge length and ≤ 30 mm in maximum cross-sectional dimension, supporting standardized test geometries per ASTM D638 (plastics), ASTM D412 (rubber), and ISO 37 (vulcanized rubber). Grip options include pneumatic parallel-jaw clamps (standard), wedge-action grips for metallic foils, and custom fixture interfaces for micro-electromechanical components (e.g., SMT solder joints, flex circuit traces, miniature springs). While not certified to EN ISO 12100 or CE-marked as a standalone machine, the system complies with IEC 61000-6-2/6-3 for electromagnetic compatibility and operates within Class II electrical safety limits per GB/T 3836.1–2021. All mechanical tests performed using this instrument are fully traceable to SI units and support audit-ready reporting for internal quality systems aligned with ISO 9001:2015 and IATF 16949 requirements.

Software & Data Management

The tester operates in standalone mode via its embedded controller but supports optional PC-based data acquisition through RS-232 or USB-to-serial interface. Compatible with Jianhu’s free JH-TestSuite Lite software (Windows 10/11), users can configure multi-step test profiles—including preload, ramp-to-load, dwell, and return sequences—as well as export raw ASCII-formatted .csv files containing time-stamped load (N), displacement (mm), and strain-derived values. The software enforces user-access levels (operator, supervisor, administrator) and maintains local audit trails for method changes, calibration events, and test execution logs—facilitating basic 21 CFR Part 11 readiness when deployed in regulated manufacturing settings. Calibration intervals are recommended every 12 months or after 5,000 test cycles, with NIST-traceable verification kits available upon request.

Applications

• Tensile bond strength verification of adhesive-coated PCB substrates and conformal coatings
• Peel resistance quantification of laminated film packaging and medical device pouch seals
• Yield behavior analysis of thermoplastic elastomer (TPE) gaskets used in IP67-rated enclosures
• Mechanical integrity screening of miniature fasteners, crimped terminals, and micro-springs in automotive sensors
• Elongation-at-break assessment of silicone rubber O-rings and diaphragms per USP extractables protocols
• Quality gate testing of injection-molded nylon clips prior to final assembly in consumer electronics

FAQ

What is the maximum allowable specimen thickness for standard jaw grips?
Standard parallel-jaw grips accommodate specimens up to 8 mm thick; optional high-clearance grips extend this to 15 mm.
Does the system include built-in overload protection?
Yes—mechanical end-stop switches and software-imposed force ceiling (configurable up to 105% of rated capacity) prevent transducer damage.
Can test results be exported directly to Excel or LIMS platforms?
Raw CSV output is natively supported; third-party LIMS integration requires middleware configuration via ODBC or API adapters.
Is ISO/IEC 17025 calibration documentation included with purchase?
A factory calibration report with uncertainty budget is supplied; accredited third-party calibration (e.g., CNAS or A2LA) is available as an add-on service.
What maintenance schedule is recommended for long-term repeatability?
Bi-weekly visual inspection of grip surfaces and lead screw lubrication; annual recalibration and drive belt tension verification.
