Product Overview
This computerized universal mechanical testing system delivers high-precision tensile, peel, compression, and puncture testing tailored specifically for battery manufacturing and advanced materials characterization. Engineered to determine the physical integrity of battery electrode tab welds, separator membranes, current collector foils, and flexible packaging laminates, this equipment provides dependable quantitative data essential for process optimization, failure analysis, and quality assurance.
Designed for integration into both battery research and development laboratories and industrial quality control departments, the system accommodates a broad array of specimen formats. Beyond energy storage components, the unit readily evaluates plastic films, metal foils, medical adhesives, release papers, and composite laminates, adapting quickly to diverse testing standards through modular tooling and intuitive software control.
Constructed with premium structural components, an anti-overload S-type alloy steel load cell, and a low-vibration precision drive mechanism, this testing platform guarantees reliable repeatability and minimal baseline noise. It delivers consistent, metrology-grade measurement precision under rigorous, high-throughput testing cycles.
Key Features
- High-Precision S-Type Load Cell: Utilizes a resilient S-type alloy steel load sensor capable of achieving Class 0.5 accuracy with an effective load measurement accuracy of ±0.5% and a force resolution of 1/250,000, ensuring maximum measurement fidelity across micro-force and high-load ranges.
- Precision Ball Screw Drive System: Built with an industrial-grade Taiwan TBI ball screw assembly and a high-performance low-noise motor, providing smooth linear travel, exceptional straightness, minimal axial play, and stepless speed adjustment from 0.5 mm/min to 500 mm/min.
- Windows-Based PC Control & Real-Time Analytics: Operates through a dedicated Windows software environment featuring interactive dialog configuration, multi-graph real-time curve rendering (load vs. displacement, load vs. time, stress vs. strain), and automated peak force capture.
- Multi-Mode Mechanical Testing: Supports four standard automated operational routines, including fracture/breakage destruction testing, constant load holding, specified deformation holding, and timed load retention for comprehensive mechanical profiling.
- Flexible Multi-Unit Measurement Conversion: Facilitates instantaneous digital switching across global standard units for force (N, kN, kgf, gf, lbf), stress/strength (MPa, kPa, Pa, kgf/cm², lbf/in²), and displacement (mm, cm) without manual recalculations.
- Automated High-Speed Return Cycle: Automatically logs test data and commands the crosshead to return at maximum speed to the original datum point immediately upon specimen fracture or test completion, maximizing sample throughput.
- Comprehensive Multi-Tiered Safety Architecture: Safeguards testing hardware and operators via built-in overload protection, mechanical over-travel limits, software travel boundaries, over-time cutoffs, rapid crush detection, and a physical emergency stop interface.
- Integrated Metrological Calibration Routine: Features a built-in calibration module designed for swift recalibration, verification, and certification by third-party metrology and accreditation bodies.
- Rugged A3 Steel Construction: Encased in heavy-gauge A3 structural steel with an electrostatic powder-coated protective finish, delivering outstanding rigidity, chemical resistance, and long-term durability in industrial environments.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Battery Tab Welding Quality | Measures the tensile peel and shear strength of ultrasonic and laser-welded tabs on cathode and anode current collectors. | Prevents internal open circuits and contact resistance spikes by verifying joint integrity before cell assembly. |
| Battery Separator Puncture Testing | Evaluates the puncture resistance and tensile yield strength of micro-porous polyethylene, polypropylene, and ceramic-coated separators. | Assesses barrier resistance against dendrite penetration to eliminate short-circuit risks in high-energy cells. |
| Metal Current Collector Characterization | Quantifies elongation, tensile strength, and tear propagation across ultra-thin copper and aluminum foils. | Optimizes coating tension parameters and reduces foil breakage during high-speed roll-to-roll electrode processing. |
| Aluminum-Plastic Film Peel Testing | Determines the bond strength, interlayer adhesion, and seal integrity of pouch cell casing laminates. | Guarantees hermetic sealing performance and prevents electrolyte leakage or ambient moisture ingress over cell lifespan. |
| Adhesive Tape and Protection Film Peeling | Performs 90-degree and 180-degree peel resistance tests on functional tapes, release liners, and protective films. | Ensures uniform adhesion and residue-free removal during automated battery pack and electronics manufacturing. |
| Medical Patches and Package Sealing | Evaluates tensile strength, peel resistance, and elongation of transdermal patches, sterile wraps, and medical adhesive tapes. | Validates package seal integrity and compliance with rigorous healthcare and sterile packaging standards. |
| Polymer and Composite Film Mechanics | Tests tensile modulus, yield point, and breaking strength of flexible packaging, woven materials, and synthetic films. | Delivers precise mechanical profiling to satisfy international packaging, polymer, and paper testing protocols. |
