“Rub” Out Your Noise And Vibration Issues With Rubber Molding
Noise and vibration can be controlled in various ways, including blocking, absorbing, isolating and damping the noise source. The dictionary defines damping as “the dissipation of energy by conversion to heat.” Because rubber has such a low damping factor, it is one of the best materials for noise and vibration control. That’s why rubber molding is an effective means of controlling noise, vibration and shock. How exactly does damping with rubber molding work? By reducing resonant vibration, it effectively mitigates both structural and impact noise. In effect, it produces a reduction in the inaudible sounds that are carried by structural surfaces. If these sounds are inaudible, why do they need to be reduced? Because at resonance (increase in amplitude of oscillation), a considerable amount of audible airborne noise may be generated by that sound. While damping does not absorb the noise’s initial impact, in terms of both time and magnitude, it does reduce the “pinging’ or “roar” that results from that impact. Whether the environment producing the noise is nautical, electrical, computer-related, aeronautical, or business-machine-applicable, rubber molding can eradicate the offending sound and vibration. When considering a rubber molding noise and vibration solution, look for a line of isolators and mounts that come in a variety of styles and sizes. From one pound to one ton, the right type of mount for your application is vital. Also, keep in mind that the thicker the damping material is, the more noise and vibration it will control. No matter what the source of your vibration isolation problem, if you keep these recommendations in mind, the noise, vibration and shock you’re currently contending with can be efficiently controlled. Choose a leader in the rubber molding industry, one that’s established a long track record of producing custom molded rubber parts, and that noise and vibration problem of yours won’t be a problem for very much longer.
