GuanCe Instruments GCWDS-5K Microcomputer-Controlled Electromechanical Universal Testing Machine

Overview

The GuanCe Instruments GCWDS-5K Microcomputer-Controlled Electromechanical Universal Testing Machine is a high-precision, floor-standing portal-frame system engineered for static mechanical property characterization of metallic, polymeric, ceramic, composite, and fibrous materials. It operates on the principle of electromechanical force application via dual precision ball-screw-driven crosshead motion, controlled by an AC servo motor and high-resolution digital feedback loops. Designed to meet international metrological requirements for materials testing laboratories, the GCWDS-5K delivers traceable, repeatable, and compliant results across tensile, compression, flexural, peel, shear, tear, puncture, and burst test modes — including optional integration with environmental chambers for elevated or sub-ambient temperature testing. Its Class 0.5 accuracy rating per ISO 7500-1 and GB/T 228.1 ensures suitability for R&D validation, quality control release testing, and regulatory submission in industries governed by ISO/IEC 17025, GLP, and GMP frameworks.

Key Features

• Robust portal-style frame with four-column load-bearing architecture and fully powder-coated steel construction for long-term dimensional stability and vibration damping.
• Dual high-precision, zero-backlash ball screws driven by a high-torque AC servo motor with synchronous timing belt transmission — enabling smooth, quiet, and wear-resistant crosshead movement over the full 650 mm effective stroke.
• Advanced SmartTest™ digital controller featuring three synchronized analog input channels (for load cell and extensometer signals), 120,000-count AD resolution, and real-time 4× quadrature encoding for displacement measurement at 0.01 mm resolution.
• Force measurement via radial-load-capable wheel-type load cell with 0.05% FS linearity and ±1% relative accuracy across 0.4–100% of full scale (5 kN).
• Programmable crosshead speed range from 0.05 to 850 mm/min with ±1% speed fidelity and automatic stop-on-fracture functionality.
• Dual-stage safety protection: programmable software limits plus mechanical overload cutoff (3–5% over full scale) to prevent hardware damage during unexpected failure events.
• Windows-based GUI software supporting multi-step test protocols, real-time curve overlay, automated parameter extraction (yield strength, ultimate tensile strength, modulus, elongation at break), and export to CSV, PDF, and XML formats.

Sample Compatibility & Compliance

The GCWDS-5K accommodates standard and custom specimens up to 600 mm wide and 650 mm tall, compatible with flat, round, sheet, film, fiber bundle, and molded bar geometries. Gripping options include wedge-action pneumatic, hydraulic, and manual vise configurations; optional extensometers support strain-controlled testing per ASTM E83 and ISO 9513. The system is validated for conformance with ISO 7500-1 (static calibration), ISO 5893 (dynamic performance), and national standards including GB/T 228.1 (metallic materials), GB/T 1040.2 (plastics), GB/T 9341 (flexural properties), and YY/T 0680 (medical packaging). Data integrity meets audit-trail requirements under FDA 21 CFR Part 11 when deployed with user-access controls and electronic signature modules.

Software & Data Management

The embedded SmartTest™ software provides a modular, intuitive interface built on Microsoft .NET Framework and native Windows OS. It supports test method templates aligned with ASTM, ISO, and GB standards, allowing rapid setup of multi-cycle loading profiles, hold steps, and conditional logic (e.g., “stop at 5% strain”). All raw data — including time-stamped force, displacement, and extensometer signals — are stored in encrypted binary archives with metadata tagging (operator ID, sample ID, calibration certificate number, environmental conditions). Audit logs record every user action, parameter change, and calibration event. Export functions comply with LIMS interoperability standards and support direct integration into enterprise QA/QC databases via ODBC and RESTful API extensions.

Applications

• Mechanical qualification of aerospace aluminum alloys, titanium sheets, and carbon-fiber-reinforced polymer (CFRP) laminates per AMS and NADCAP requirements.
• Quality assurance of medical device packaging (sterile barrier systems) per ISO 11607 and ASTM F88/F904.
• Characterization of elastomeric seals, gaskets, and catheter tubing under tensile and compression creep protocols.
• Development and validation of biodegradable polymers used in orthopedic fixation devices (e.g., PLLA, PCL) under ISO 10993-12.
• Structural evaluation of civil engineering composites, geotextiles, and reinforced concrete specimens per ASTM C39, C78, and EN 12390-3.
• Academic research in material science departments requiring reproducible stress–strain mapping, fracture toughness estimation, and viscoelastic modeling inputs.

FAQ

What standards does the GCWDS-5K support out-of-the-box?

The system includes pre-configured test methods for ASTM E8/E9/E21, ISO 6892-1/15630-1, GB/T 228.1–2021, and JIS Z2241, with customizable templates for proprietary or emerging standards.
Can the GCWDS-5K be integrated with external environmental chambers?

Yes — the controller provides TTL-level trigger I/O and RS-485 communication ports for synchronized thermal chamber control and data correlation during temperature-dependent testing.
Is third-party calibration certification included?

Each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards; optional UKAS or A2LA-certified recalibration services are available upon request.
Does the software support multi-user role-based access control?

Yes — administrator, operator, and reviewer roles can be defined with granular permissions for method editing, test execution, report generation, and audit log review, satisfying 21 CFR Part 11 compliance requirements.
What is the recommended maintenance interval?

Biannual verification of load cell linearity, crosshead alignment, and encoder resolution is advised; annual recalibration is recommended for GLP/GMP-regulated environments.
