How to improve the noise reduction performance of sintered brass and bronze muffler- Ningbo Jiangbei District Cicheng Pneumatic Components Factory.

Sintered metal silencers have excellent noise reduction performance due to their unique multi-stage noise reduction structure and material properties. The core of this performance lies in the powder metallurgy process used, which uses high temperature and high pressure to sinter brass or bronze powder into a high-density, high-strength and well-porous noise reduction component. This sophisticated structure not only gives the silencer excellent physical properties, but also greatly enhances its noise reduction ability. The multi-stage noise reduction structure is the key to sintered metal silencers. Its design usually includes multiple channels with different apertures and lengths. These channels are precisely calculated and designed to effectively guide the complex interaction of sound waves during propagation to achieve the ideal noise reduction effect.

In order to further optimize its noise reduction performance, the channel design of the sintered metal silencer has been deeply adjusted. The shape, size and arrangement of the channels have been rigorously calculated to ensure that the sound waves can achieve maximum reflection, interference and energy dissipation during propagation. This sophisticated design not only significantly reduces the energy output of the sound waves, but also effectively shortens the propagation distance of the sound waves, thereby improving the overall noise reduction efficiency. In addition, the surface roughness inside the channel is also strictly controlled to reduce the energy loss of sound waves during propagation and further enhance the noise reduction effect.

Material selection also plays an important role in the noise reduction performance of sintered metal silencers. Brass and bronze, as the main alloy materials, have excellent physical properties and chemical stability. Brass is known for its good thermal conductivity and corrosion resistance, and can maintain stable noise reduction performance in harsh environments such as high temperature and high humidity. Bronze, on the other hand, exhibits higher hardness and wear resistance, and can maintain long-term stable noise reduction effects under large vibrations and shocks. The effective combination of these two materials enables sintered metal silencers to demonstrate excellent noise reduction capabilities in various industrial environments.

In addition, sintered metal silencers also use advanced manufacturing processes and technologies to ensure the continued stability of their noise reduction performance. During the manufacturing process, key parameters such as sintering temperature, pressure and time are precisely controlled to ensure that the internal structure of the silencer is in the best state, thereby achieving the best noise reduction effect. At the same time, the use of modern surface treatment technologies, such as sandblasting and polishing, further improves the smoothness of the silencer surface, reduces surface roughness, reduces the energy loss of sound waves during propagation, and further improves noise reduction performance.
