The noiseless steel is an acoustically constructed product specifically designed to reduce noise and vibrations. Our noiseless steel is a sandwiched steel panel consisting of two sheets of metal with a visco-elastic inner layer that results in a metal/plastic/metal (MPM) panel, its effective combination of the metallic material and the polymer material makes it characterized both with the original mechanical performance and the processing formability etc, and with the damping property of the polymer material, contributing it to be the ideal environmental product replacing the metallic material, applicable in the surrounding of vibration and noise.
The product is available in a wide range of material types, grades, sizes, and thicknesses. When both sheets of metal are of the same thickness, the system is described as symmetrical. If they are of different thicknesses the system is asymmetrical. Symmetrical MPM systems provide slightly better vibration damping than asymmetrical systems with the same total weight, but the difference is small as long the asymmetry ratio does not exceed 1:4. MPM panels can also be supplied in special materials, such as stainless steel, aluminum, cold rolled steel, and deep-drawn steel. Different materials can also be combined - for example stainless steel on one side and aluminum on the other. We can prepare material in either mill finish or pre-painted form. Contact corrosion is effectively prevented, since the plastic inner layer isolates the plates from each other.
The specification as follows:
Thickness(mm):0.4-3.0, tolerance: +/-0.05
Width(mm):600-1250, tolerance: +/-1
Length(mm): 100-2500, tolerance: +/-2
The products can be widely used in
Domestic appliances: Base and housing of the air conditioner, washing machine and refrigeration etc; Automobile: casing of the oil tray, fuel tank, gear box and the engine;
Engineering Machinery: cover and housing of the diesel engine, inner-combustion engine, blower, compressor etc;
Architecture: door, floor slab, staircase slab of the sports stadium, music hall, cinema etc and the sound-isolate wall panel of the industrial-oriented workshop;
Communication: sound-absorption panel of the expressway, elevated highway, railway and so on.
