NEW YORK, Nov. 7, 2016 /PRNewswire/ -- NVH stands for noise, vibration, and harshness, and the noise is what the driver and passengers can hear, the vibration is what they can feel and the harshness is how much of an effect thumps, bumps, noise and vibration have on the cabin and its occupants. It is an aggregative indicator with which to measure the quality of automobile manufacturing. As many as one-third vehicle faults are related to the NVH of vehicles. Automotive NVH parts can fall into shock absorber products and noise reduction products, of which the former includes rubber shock absorber products and spring damping shock absorbers while the latter consists of sound insulation products and sealing products. 1.Rubber Shock Absorber Product Market In recent years, with the rapid growth of automobile output in China, the market size of rubber shock absorber products has kept expanding, to reach RMB18.635 billion in 2015; wherein the proportion of OEM market came to 74% and AM market 26%. China's automobile industry will enter a stage of low-speed growth during 2016-2020, when the growth rate of shock absorber product market will also slow down to around 6%. At present, there are only 50 or so rubber shock absorber product manufacturers in China that have entered OEM passenger vehicle market. Moreover, few enterprises have the capability of synchronous R&D, system integration and supply, and thus some high-grade rubber shock absorber products have to be imported from overseas. Major enterprises include Tuopu Group, Anhui Zhongding Damping Rubber Technology Co., Ltd., and JX Zhao's Group Corp. 2.Sound Insulation Products Market In 2015, the market size of sound insulation products (mainly used in OEM market) in China totaled about RMB22.05 billion. As the output of automobiles grows, the figure is expected to reach RMB 28.31 billion in 2020. Given the fact that sound insulation products have relatively low technical requirements, the Chinese enterprises can basically meet the supplying demand from domestic automobile manufacturers, with adequate market competition. At present, there are more than 100 sound insulation product producers in China, mainly including Tuopu Group, Changshu Automotive Trim, as well as Shanghai Car Carpet Plant. It is crucial for Automotive NVH parts manufacturers to have the capacity of synchronous R&D and system integration. Currently, China is relatively weak in system integration, and only a few domestic enterprises such as Tuopu Group,Anhui Zhongding Sealing Parts and Zhuzhou Times New Material Technology have certain competence of development and system integration. Tuopu Group has more powerful NVH system integration capability, successively participating in the synchronous research and development of auto makers including Shanghai GM, Chrysler, BMW, Audi, Volvo, SAIC, Changan Ford, and Changan Auto. Meanwhile, the company has also established long-term cooperative relationship with world-renowned automotive system integration providers like Valeo, Faurecia, and Benteler.
