A resin silencer with a sound-absorbing structure is installed near the hole that leads to the interior of the vehicle, and is a part that reduces transmitted sound while driving.

This product is compatible with various car body hole shapes. It is a part that achieves both improved recyclability through the use of a mono-material and improved quietness.

Silencer

It is possible to increase the quietness of the car.
A sound absorbing structure that converts sound energy into heat energy through a structure that vibrates in a certain frequency band.
Acoustic analysis can be used to control the frequency band that absorbs sound.

Proposals that take Advantage of the Flexibility of Resin Shapes

With the electrification of cars and the absence of an engine, road noise and other sounds that enter the interior become noticeable. Nifco contributes to the creation of a better vehicle interior environment by proposing components that absorb sound at the target frequency.

Door Service Hole Cover

It is possible to increase the quietness of the car.
Compatible with conventional PP body + seal sponge only with soft materials.
Water can be stopped both from inside and outside of the car.

Sealability

By devising the shape of the fastening part (adopting a waterproof structure on both sides),
Increased followability to the mounting object, and improved water stop and NV performance.
