The Bone Plates Static Four-Point Bending Tester is a specialized mechanical testing device used to evaluate the structural strength and stiffness of orthopedic bone plates under static loading conditions. By applying controlled forces at four points along the plate, the machine simulates bending stresses similar to those experienced in the human skeletal system. It measures key mechanical properties such as bending strength, flexural stiffness, and deformation until failure. This data helps manufacturers, researchers, and clinicians ensure that bone plates meet safety and performance standards for orthopedic fixation applications.

Standard

(1)YY/T 0342-2022: Chinese standard specifying methods for determining bending strength and equivalent bending stiffness of straight and pre-angled metallic bone plates.

(2)ASTM F382: International standard covering mechanical testing, dimensional requirements, and reporting protocols for metallic bone plates.

Product Advantages

(1)High-Precision Force Application:

Electromagnetic load frame with ±0.1% accuracy, ensuring compliance with YY/T 0342’s force resolution requirements.

Adjustable test speed (0.001–500 mm/min) for static and quasi-static loading.

(2)Customizable Fixturing:

Modular four-point bending clamps with interchangeable roller diameters (6–13mm) and contour-matching designs to accommodate straight, angled, and pre-curved bone plates.

Anti-slip mechanisms and specimen alignment guides for consistent results.

(3)Advanced Data Acquisition:

Real-time monitoring of force, displacement, and bending stiffness with 5000Hz sampling rate.

Automatic calculation of key parameters: bending strength (MPa), equivalent stiffness (N/mm), and yield points.

(4)User-Centric Design:

Intuitive software with preloaded SOPs for YY/T 0342 and ASTM F382 compliance.

Multi-language interface (English/Chinese/Spanish) and exportable reports (PDF/Excel/CSV).

(5)Durability & Safety:

Corrosion-resistant steel frame and overload protection system for long-term reliability.

Low-noise operation (<65 dB) suitable for laboratory environments.
