In metallurgy, machinery manufacturing and scientific research sectors, verifying the reliability and safety of metal components under sudden high-impact loads is critical. As a leading supplier of material testing equipment, Mikrosize proudly presents its flagship microcomputer-controlled automatic impact testing machine. This precision instrument accurately evaluates the impact resistance and toughness of metallic materials, generating reliable data to support quality control and new material development. Fully compliant with Chinese national standards GB/T 3803-2002 and GB/T 229-2007, this tester is an essential piece of laboratory and QC workshop equipment for enterprises pursuing strict quality compliance.
Mikrosize automatic impact testers come in four heavy-duty models: 300C, 450C, 600C and 750C, covering impact energy ranging from 300J to 750J. Such wide energy coverage meets diverse testing demands for both low-energy and high-energy metallic specimens, delivering consistent, precise test results for all material types.
Superior Performance & Core Advantages
1.Intelligent Microcomputer & PLC Full Automatic Control
The tester adopts an integrated industrial PC and PLC control system to automate the full testing workflow, including pendulum lifting, impact triggering, automatic data calculation and result display. The system instantly computes and displays key indicators such as impact absorption energy (KV), impact toughness and pendulum swing angle, and can automatically calculate average values for multiple test groups. Equipped with a built-in printing module, it supports one-click generation of single-test and average-value test reports. After each impact cycle, the system automatically offsets residual pendulum energy and resets the pendulum to its standby position for the next test. This high level of automation greatly simplifies operation, boosts testing efficiency and guarantees outstanding measurement precision.
2.Reinforced Dual-Column Main Frame Structure
The machine’s main body features a rigid dual-support column design, paired with a simply supported main shaft and pendulum hanging assembly. This structural design optimizes radial load distribution on bearings. For high-energy models (600C, 750C), it effectively reduces main shaft deformation and minimizes energy loss caused by bearing friction. Almost all preset impact energy is transferred to the specimen, ensuring high repeatability and authenticity of every test result.
3.Stable, Smooth Pendulum Lifting System
A standard two-stage geared motor drives the pendulum lifting mechanism, enabling steady, jerk-free vertical movement. It locks the pendulum at a fixed starting position consistently, eliminating position deviation that may compromise test accuracy and stabilizing overall instrument performance.
4.Hydraulic Damping for Gentle Pendulum Lock & Release
The pendulum holding mechanism adopts hydraulic damping technology. It delivers an exceptionally smooth lock and release process without harsh mechanical shocks, extending the service life of core mechanical parts and maintaining long-term testing stability and precision.
5.High-Precision Calibrated Pendulum with Standard Impact Center
Each pendulum is designed via 3D CAD and processed with precision machining. The impact center is strictly standardized, and the pendulum’s moment of inertia undergoes precise factory calibration. Accurate pendulum torque is the foundation of reliable impact energy calculation, making this tester highly stable for long-term batch testing.
6.Easy Maintenance & Comprehensive Safety Protection
The consumable impact blade is fixed with standard screws for quick disassembly and replacement to retain consistent cutting sharpness. A built-in specimen ejection mechanism automatically pushes out broken samples after testing to streamline operation.
Safety design is prioritized throughout the equipment: safety lock pins and an all-round heavy-duty safety net fully enclose the test zone, preventing flying fragments from injuring operators during impact tests.
