The ASTM F543 standard specifies the torque required to measure the insertion and extraction of metal bone screws from standard materials, in order to confirm the consistency of the tested product. Hengli maintains 11.17N and rotates at a rate of 3r/min for 4 turns, followed by 4 turns.
The UnitdTest UT1050 series Metal bone screw torsion testing equipment has a lightweight body, easy operation, and precise control, making it suitable for bone nail testing. We provide you with professional testing fixtures to meet standard requirements, as well as precise and effective test plans (SOP), and optional data post-processing software to reduce the difficulty of data processing and assist in the mechanical performance analysis of metal bone screws.
Product features:
A new generation fatigue testing system with small electromagnetic motors as the driving core;
◆ Meet the strict requirements of material mechanics testing for high-precision, high-frequency, high stability, and durability in biological material mechanics experiments;
◆ Optional torsion channel for multi axis tension and torsion loading;
◆ Can perform tests such as stretching, compression, bending, shearing, twisting (optional), creep, relaxation, etc;
◆ Suitable for testing metal materials, microelectronic materials, polymer materials, and biomaterials;
Multiple fixtures and accessories are available for selection.
