JMZ-TK Series
Redefining Precision Equipment Protection — Xi'an Hoan JMZ-TK Friction Damping Vibration Isolator
In today's era of rapid industrial and technological advancement, the stable operation of precision instruments, communication devices, and high-end manufacturing systems increasingly depends on outstanding vibration control solutions. Xi'an Hoan Microwave Co., Ltd., a frontrunner in China's vibration and noise control sector, has introduced the JMZ-TK series friction damping vibration isolators, which are redefining the protection standards for precision equipment with their unique engineering philosophy.
Traditional vibration isolators often rely on elastic media such as rubber, springs, or air. They perform fairly well in handling high-frequency vibrations, yet when confronted with sudden impacts or low-frequency oscillations, they tend to produce excessive amplitudes and persistent residual vibrations — a fatal threat to precision equipment. The core breakthrough of the JMZ-TK series lies in its adoption of the "Coulomb friction damping" mechanism. This is a precisely calculated and controlled dry friction damping technology; by building a controllable friction force field inside the vibration isolation system, it can instantly and efficiently convert impact kinetic energy into heat energy for dissipation.
The superiority of this mechanism is evident. When equipment is impacted, the JMZ-TK vibration isolator does not "bounce" like traditional products. Instead, it generates a nearly constant damping force via internal friction pairs, like a pair of powerful "hands" firmly holding and stabilizing the equipment to quickly suppress vibration. As a result, the equipment's transient response is greatly reduced, and reset time is significantly shortened, effectively preventing damage, loss of precision, or signal interruption of precision components caused by excessive displacement or repeated vibration.
The JMZ-TK series is specifically designed for scenarios with extremely high stability requirements, such as microwave communication base stations, high-precision machine tools, optical experiment platforms, and semiconductor manufacturing equipment. It is not merely a vibration isolation component, but a "guardian" of equipment reliability and service life. Leveraging its profound accumulation in material science and structural mechanics, Xi'an Hoan ensures that JMZ-TK products not only deliver exceptional performance, but also feature weather resistance, long service life, and high reliability, providing a solid foundation for precision industries in China and beyond.
