Equipment name: Microcomputer controlled bone screw torsion testing machine

Models: CTT4101, CTT4201, CTT4501, CTT4102

Product Overview: The TTM-201 electronic torsion testing machine for bone screws is suitable for testing and analyzing the torsional mechanical properties of metal materials, non-metal materials, composite materials, as well as medical devices such as bone screws, biomaterial surgical implants, bone joint implants, intramedullary fixators, metal bone screws, hollow bone screws, etc. Can automatically calculate TeH, TeL, Tm τ EH τ EL τ M τ Test parameters such as p0.2 and G. Can meet special testing requirements of users. It can achieve closed-loop control such as constant rate loading, constant rate torque angle, and constant rate angle, and can conduct process qualification performance verification tests on materials or products. Equipped with a torsion angle extensometer, it can automatically calculate the shear modulus G, and the test results can be saved, queried, and printed.
