Locally resonant metamaterials have emerged as effective solutions for several types of NVH problems over the last few years, since they offer better performance of noise and vibration reduction than other NVH solutions. However, there have not been many cases that extend to the industrial applications, due to limitations which are often linked with design requirements, such as robustness, lightness and durability. In this paper, the authors propose a novel struc-tural design which is feasible for mass production of locally resonant metamaterial that im-proves the productivity for industrial application. The proposed structure is made of metal in-sert injection molding. It enables mass production with insert injection and effectively joins plastic with metal. The manufactured model is applied on a thin plate structure, and experi-mentally verified. It is observed that the proposed structure effectively reduces the noise and vibration at the target frequency band, and is relatively superior to other vibration treatments such as deadeners. So, the proposed structure of locally resonant metamaterial is expected to be applicable to various industrial fields such as automobiles and home appliances.
