Cometech QC-950 Series: Computerized High-Capacity Hydraulic UTM

The Ultimate Solution for Heavy-Duty Material Testing (300kN to 2000kN)

The QC-95x Series represents Cometech’s most powerful testing solution, specifically engineered for testing high-strength materials. By integrating robust mechanical engineering with advanced servo-hydraulic control, these machines provide the reliability needed for metallurgy, civil engineering, and structural research.

Comprehensive Technical Advantages

  • Ultra-Rigid 4-Column Load Frame:

    The load frame is constructed with a 4-column architecture, providing exceptional lateral stiffness. This minimizes frame deflection under extreme loads, ensuring that displacement measurements are highly accurate and reflective of actual specimen behavior.

  • Precision Servo-Hydraulic Control:

    Utilizing high-frequency servo valves in a closed-loop system, the QC-950 series allows for precise control over load rates, displacement rates, and strain rates, meeting the strict requirements of international standards like ASTM E8 and ISO 6892.

  • Optimized Dual-Space Architecture:

    To maximize efficiency, the machines feature a dual-space test area:

    • Upper Zone: Dedicated to Tensile testing with specialized hydraulic grips.

    • Lower Zone: Designed for Compression, Bending, and Shearing tests, allowing users to switch between test types without disassembling heavy fixtures.

  • Powered Hydraulic Gripping System:

    The side-action hydraulic grips provide immense clamping force, preventing specimen slippage even with hardened steels. The system is operated via a remote console, enhancing operator safety and reducing setup time.

  • Advanced PC-Based Analysis Suite:

    The integrated software provides professional tools for real-time curve monitoring (Stress/Strain, Load/Time). It features a comprehensive library of test methods and automated post-test calculations for Yield point (Offset/Hysteresis), Tensile strength, and Modulus of Elasticity.

Application & Model Selection Guide

Model Max Capacity Drive System Target Applications
QC-952 300 kN Hydraulic Servo Aluminum alloys, light rebars, composite materials.
