Beiguang Jingyi BWN-300KN Desktop Microcomputer-Controlled Electromechanical Universal Testing Machine

Overview

The Beiguang Jingyi BWN-300KN is a high-precision, desktop-mounted electromechanical universal testing machine engineered for static mechanical property evaluation of metallic and non-metallic materials under tension, compression, bending, shear, and peel loading conditions. It operates on the principle of controlled displacement actuation via a precision ball-screw-driven crosshead, coupled with real-time force feedback from a calibrated load cell and high-resolution position sensing. The system complies with fundamental metrological requirements outlined in ISO 7500-1 (metallic materials — calibration of static uniaxial testing machines) and ASTM E4 (standard practices for force verification of testing machines), ensuring traceable force measurement integrity across its operational range. Designed for laboratory and quality control environments, the BWN-300KN delivers repeatable mechanical data essential for material qualification, process validation, and compliance reporting in regulated sectors including aerospace, automotive, and structural steel manufacturing.

Key Features

• High-rigidity four-column guided crosshead structure with graphite self-lubricating bushings, minimizing lateral deflection and ensuring axial alignment during high-load testing.
• Panasonic AC servo motor (3.2 kW) paired with Hitec servo drive for precise speed control, achieving crosshead velocity accuracy within ±1% of setpoint across the full 0.001–500 mm/min range.
• Imported U.S.-made QL (Quanli) load cell rated at 100 kN (optional upgrade to 300 kN), certified to ISO 376 Class 0.5 accuracy, with thermal drift compensation and long-term stability <±0.02% FS/year.
• ABBA precision ground ball screw transmission system with preloaded nut assembly, delivering sub-micron positioning repeatability and eliminating backlash during bidirectional motion.
• Dual-channel 5 MHz optical encoder interface supporting high-speed displacement acquisition and optional extensometer integration for true strain measurement.
• Embedded SOC-based controller with 300 Hz analog-to-digital sampling rate, 24-bit resolution per channel, and adaptive neural-network PID control architecture—eliminating manual tuning while maintaining robust transient response.

Sample Compatibility & Compliance

The BWN-300KN accommodates standard metallic specimens per ASTM E8/E21 (tensile testing of metallic materials), ISO 6892-1, and GB/T 228.1. Its 450 mm test width and 550 mm effective tensile stroke support flat sheet, round bar, wire, and machined dog-bone geometries up to Ø32 mm diameter or 40 mm width. Compression testing adheres to ASTM E9 and ISO 3126 protocols using dual-faced hardened steel platens. All hardware—including X204 tensile grips and YS204 compression fixtures—is designed for minimal slippage and uniform stress distribution. The system supports GLP-compliant audit trails when operated with SUPERTEST software configured for 21 CFR Part 11 compliance (electronic signatures, user access controls, and immutable data logging). Calibration certificates issued by CNAS-accredited laboratories are provided with each unit.

Software & Data Management

SUPERTEST v3.x is a Windows-based, modular test platform offering ISO/IEC 17025-aligned workflow management. It features intuitive graphical test configuration, real-time curve overlay (force–displacement, stress–strain), automated yield point detection per ASTM E111, and customizable report generation in PDF/XLS formats compliant with internal QA templates. Raw data export includes timestamped .csv files with metadata (operator ID, environmental conditions, calibration IDs). The software integrates seamlessly with LabVantage and LIMS platforms via OPC UA and supports scheduled automatic backups to network drives. Firmware updates are delivered remotely through encrypted HTTPS channels, preserving configuration integrity and version-controlled audit history.

Applications

• Mechanical characterization of carbon steels, stainless alloys, aluminum extrusions, and titanium grades per ASME BPVC Section II and EN 10002-1.
• Quality assurance of welded joints and heat-affected zones (HAZ) in structural fabrication.
• Validation of cold-forming behavior and springback prediction in sheet metal stamping processes.
• Compliance testing for automotive component suppliers against VDA 238-100 (bending strength) and SAE J2334 (fatigue pre-screening).
• Research-grade tensile analysis in university metallurgy labs, including modulus-of-elasticity determination, ultimate tensile strength (UTS), elongation at break, and reduction-in-area quantification.

FAQ

What standards does the BWN-300KN comply with for force calibration?

It meets ISO 7500-1 Class 0.5 and ASTM E4 requirements, with factory calibration traceable to NIM (National Institute of Metrology, China) via CNAS-accredited third-party verification.

Can the system be integrated into an existing MES or ERP environment?

Yes—via Ethernet-based TCP/IP communication, OPC UA server module, and configurable RESTful API endpoints for bidirectional data exchange.

Is extensometer compatibility supported for Poisson’s ratio measurement?

The controller provides two dedicated high-frequency encoder inputs and analog voltage output channels compatible with clip-on, video, or laser extensometers meeting ASTM E83 Class B-2 specifications.

What is included in the one-year warranty?

Parts, labor, and on-site service coverage for defects in materials or workmanship; excludes consumables (grips, load cell overload damage) and misuse-related failures.

Does the system support multi-step cyclic testing protocols?

Yes—SUPERTEST allows programmable step sequences with conditional branching (e.g., hold at 80% UTS for 60 s, then ramp to failure), fully logged with cycle count and energy absorption metrics.
