Acoustic fiber board has a wide application,which can be used for commercial offices,hotels,restaurants,retail,multifunctional hall,art gallery,library,gymresidential cinemas,theaters and-Oauditoriums  and high requirements (high weight, Big hardness, high density, smooth surface and no needle marks). 

Firstly, the mixing must be uniform, the weight of the product is heavy, the thickness of lapped web layers is high, and the web layers must be ensured smoothly; the product must have a smooth surface, so the problem of needle marks should be solved; the smooth and flat surface of the product requires uniform temperature and even air volume of the oven. These technical problems are solved by Yingyang Company in our team led by Technical director Mr. Xu. Therefore, our products produced by Yingyang equipment have uniform thickness, uniform hardness on both sides and smooth surface, which sell well in the market, mainly export to European countries such as Germany and France etc.
