GMT - Aircraft Noise and Vibration Damping Components

Gummi-Metall-Technik (GMT) was founded with its headquarters in Buehl, Germany in 1968 and is now composed of production plants in Germany, Switzerland, Austria, Ireland, US, China, India and Malaysia. The company also has sales branches and representatives throughout the world.

Due to a global network connecting GMT plants and sales offices worldwide there is a constant flow of information throughout the group. This enables GMT to solve technical problems quickly and efficiently. Response and reaction time in cases of special customer enquiries can also be reduced to a minimum. These are some of the reasons why GMT is one of the world leaders in the field of sound and vibration dampening technology.

The production plants in Germany are certified by the European standards DIN EN ISO 9001 and DIN EN ISO 14001 as well as IRIS and EN 9100.

Noise and vibration isolating systems

Mechanical vibrations and impact stresses are the biggest problems for engines and electronic equipment on-board aircraft. Therefore, very specific noise and vibration isolating systems are used to isolate these kinds of machines from vibrations.

A wide variety of products, from simple machine feet up to high-tech parts for well-known manufacturers in the railway, shipbuilding and aerospace industries, allow GMT to meet the most challenging customer requests and wishes.

Generally, GMT products can be used wherever noise or vibrations occur. All GMT parts are manufactured to the highest quality.
