The noise of large printing presses is relatively high. At present, the international excellent printing machinery adopts a semi-closed structure. Joylenge™ melamine foam is attached to the inner wall of the enclosed space, and Joylenge™ melamine foam is also attached to the bottom. On the other hand, the absorption capacity of the foam is utilized to absorb the dripped ink. Domestic products have not used similar noise-reducing materials, so the noise of domestic products is much higher than that of foreign products, and the phenomenon of ink dripping often occurs.
Large copiers are also noisy when working, and foreign companies (such as Kodak) also use Joylenge™ melamine foam in copiers to reduce noise.
