In the modification of automobile metal parts or the structure of automobile body needs to be shaped and stress relieved, heat treatment furnaces are required, such as trolley-type heat treatment furnaces or hanging heat treatment lines. At this stage, it is necessary to use ceramic fiber modules and blankets as linings for heat treatment furnaces for metal parts.

Engine hood car sound insulation cotton, use ceramic fiber paper or thin ceramic fiber blanket to reduce the noise entering the cab. The noise of the hood will increase with the increase of vehicle speed, power, engine roar and other noises. It will enter the cockpit through various media, and a certain amount of engine noise will be placed on the hood. The heat insulation cotton can effectively reduce the transmission of the noise generated by the engine running through the air channel. The sound insulation cotton on the upper and lower hood covers of the engine can also absorb part of the noise. The exhaust pipe is a part of the engine exhaust system. The system mainly includes exhaust manifold, exhaust pipe and muffler. Generally, the one-way catalytic converter is also installed in the exhaust system to control the emission of engine pollutants. The exhaust pipe generally includes front exhaust pipe and rear exhaust pipe.

The inner layer of the door panel is made of ceramic fiber paper or thin ceramic fiber blanket. In almost all car models, the area covered by the four doors is very large, and its coverage area is second only to that of the roof and chassis. It will come into direct contact with the air while driving. In addition to the fact that designers will design a certain rounded shape for the door panel to reduce the noise caused by wind resistance, car manufacturers also know that as long as there are more car sound insulation on the inside of the door panel The large area covered by cotton can also efficiently absorb this wind noise. After dismantling the interiors of various models in the tuning shop, it was found that only cars with higher prices on the market will have this kind of sound insulation cotton on the inner layer of the door panel.
