A new material born from the pursuit of sound! Its complex characteristics are attracting significant attention.
"RASK" is a metal plate that demonstrates overwhelming power in sound absorption, sound insulation, and vibration absorption. The raw material of "RASK" is "cast iron," and the exceptional effects in sound absorption, sound insulation, and vibration absorption are a secret of this material. "RASK" is formed into a porous shape by sintering without using any foreign substances like binders. Therefore, it can be said to be a hard and heavy plate made of "100% mouse cast iron," with the surface roughness preserved as is. 【Problems Solved by RASK for Factories and Machinery】 - Measures against relocation issues due to factory vibration noise - Solutions for machinery vibration problems that can be addressed with RASK anti-vibration tables - Resolution of processing issues through vibration countermeasures For more details, please contact us or download the catalog.

Company information
Suisa Co., Ltd. is a company that conducts research and development on the movement of various waves such as vibration, sound, radio waves, and light, based on the porous cast iron "RASK." It aims to be of service to businesses and individuals. "RASK" has characteristics such as being hard like metal but possessing vibration absorption properties equal to or greater than rubber, allowing it to perform in areas and applications where existing materials cannot. There are also applied products such as wideband antenna elements, projector screens, and audio equipment that utilize the structure and concept of RASK.
