Charpy / IZOD Impact Testing Machine

Charpy and Izod Impact Testing Machines for Industrial Labs and Manufacturers


Our pendulum impact testers measure the impact strength of plastics, rubber, composites, and metals with high accuracy and repeatability. Built in-house with precision machining and verified calibration, these systems support standardized methods and flexible setups for development, quality control, and certification.


Key Features and Design Advantages


High-Precision Pendulum and Sensors


Balanced arms, low-friction bearings, and encoder-based measurement minimize energy loss and keep alignment stable through repeated cycles.


Digital and Computer-Controlled Options


Choose simple digital readouts or full software control with real-time curves, automatic calculations, databases, and report templates with streamlined export.


Multi-Energy Ranges and Interchangeable Pendulums


Select 2J–50J for polymers or up to 300J for metals. Quick-change pendulums and striker geometries reduce setup time while keeping conditions consistent.


Combined Charpy & Izod Fixtures


One frame supports both methods with modular anvils, clamps, and striker heads. Switch modes quickly without recalibration.


Safety and Ergonomics


Interlocked enclosures, shields, and automatic braking protect operators. Clear sightlines and intuitive controls improve workflow and uptime.


Test Methods and Standards Covered


Plastics & Rubber (ISO 179, ISO 180, ASTM D256, GB/T 1843)


Configure for notched or unnotched specimens, select striker radii, and condition samples to control temperature and humidity. Polymer-focused supports enable stable testing.


Metals & Composites (ASTM E23, ISO 148-1, V-Notch Charpy)


High-energy pendulums and rugged frames accommodate V-notch specimens and laminated coupons. Verified geometry and impact angle help ensure repeatability.


Models and Configurations


Analog Dial Impact Tester (2J–50J)


A cost-effective pendulum tester for plastics and rubber with mechanical energy indication and durable, precision-machined components.


Digital Impact Tester (Charpy/Izod)


Digital readouts improve resolution and repeatability. Dual-mode fixtures support ISO 179 and ISO 180 in a compact footprint.


Computer-Controlled Impact Tester (up to 300J)


For steels and high-toughness composites, automated sequences and data analysis support ASTM E23 and ISO 148-1 on V-notch specimens.


Typical Parameters and Fixtures


Options include energy capacity, striker radius, anvils, clamps, and jaw systems. Calibration kits and verification blocks align readings to reference values.


Applications and Sample Types


Plastics and Rubber Impact Strength


Assess notch sensitivity, ductile–brittle transition, and environmental effects on ABS, PC, PP, and elastomers.


Engineering Thermoplastics and Composites


Measure impact behavior of engineering resins and CFRP laminates with tailored energy and striker options.


Metal Charpy V-Notch Testing


Evaluate structural metal toughness using high-energy pendulums, robust frames, and standardized V-notch geometry.


Quality Control and R&D


Fast changeovers and reliable repeatability support incoming inspection, batch monitoring, and development.


Accuracy, Calibration, and Repeatability


In-House QC and Calibration Labs


Dedicated labs verify encoders, pendulum arms, and striker dimensions. Reference blocks and routine checks sustain stability.


Traceability and Certificates


Each unit ships with calibration records. Optional third-party verification supports audits and method compliance.


Notching and Specimen Preparation


Notch cutters, guides, and templates reduce specimen variability. Training resources help standardize preparation.


Customization and Integration


Custom Fixtures and Energy Ranges


Adapt anvils, striker radii, and clamps for unique parts and methods, from low-energy polymers to high-energy metals.


Data Integration and Reporting


Export to CSV/PDF, connect to LIMS, and automate report templates with logos and approvals.


Language/UI and Standards Libraries


Multilingual interfaces and versioned ISO/ASTM methods reduce training time and keep methods current.


Installation, Training, and Lifetime Support


On-Site Setup and Commissioning


Technicians align frames, verify sensors, and run acceptance tests. Operators receive hands-on mode-switch guidance.


Preventive Maintenance and Spare Parts


Routine checks on bearings, encoders, and fixtures, with stocked spares and prompt shipping.


Remote Diagnostics and Software Updates


Secure remote support speeds troubleshooting. Software updates add features and standards.


Accessories and Optional Kits


Notch Cutters, Anvils, and Jaws


ISO-compliant notch cutters and hardened supports maintain alignment and durability.


Temperature Conditioning Modules


Cooling/heating modules enable sub-ambient or elevated-temperature polymer tests.


Verification Blocks and Reference Specimens


Certified blocks enable daily checks and simplify audits with traceable procedures.
