| Résumé : |
Aisin Chemical Indiana, LLC (ACIN), located in Crothersville, Ind., was established in 2006. The ACIN plant, which was constructed in 2011, produces an environmentally friendly, sound-dampening, spray-type adhesive known as a damping coat for companies such as Toyota, Nissan and Subaru. A damping coat improves the cabin environment. It is applied to the floors in automobiles to reduce vibration and road noise. Previous methods of manually attaching an asphalt sheet as a sound barrier have been replaced with automatic spraying of the damping coat directly to the floor of a vehicle.
This innovation enables coatings to be sprayed onto complex shapes, such as curved and vertical surfaces, with excellent adhesion that reduces vibrational noises much more effectively than other methods. The coating is comprised of a sticky adhesive base and fibers. Sound waves from bumps in the road, resonating metal in the engine or exhaust underneath the vehicle bounce upward, and the coating provides a barrier from the inside of the vehicle. Sound waves are trapped in the pockets between the adhesive and the fibers in the coating, breaking up the energy and thereby reducing unwanted vibration and noise.
Using the spray damping coat, however, meant that ACIN needed to find a new way to handle the viscous adhesive. A special kind of pump was required. |
