Micro expanded mesh is a metal material manufactured using an expansion and stretching process. It has a strong structure, good compression resistance performance, and load capacity.
In the automotive industry, it is widely used in automotive manufacturing and aftermarket. It can provide a wide range of options and configuration variability for automotive parts and can be used as a support material, protective material, lubricating material, and filtration mesh to improve automotive performance and extend the service life of accessories.
Compared to typical extruded, sintered, or woven materials, micro expanded mesh's unique cutting and stretching technology creates no scrap and will not fall apart during processing, making them a cost-effective alternative. In addition, a variety of openings, structures (2D or 3D structures), thicknesses, and opening configurations allow micro expanded mesh to be applied in a wider range of use scenarios.
The following are some of the common uses of micro expanded mesh in automotive manufacturing: airbag filters, speaker covers, and air inlet filters.
Airbags are an important component of motor vehicle protection systems. Micro expanded mesh is used as a support and filter material to ensure reliable operation under shaking conditions and to compensate for the thermal expansion of the airbag. Micro expanded mesh used in airbags also achieves heat dissipation, filtration, and airflow distribution.
Micro expanded mesh is used in airbags for driver and passenger front, rear, head, side, knee, and seat belt applications.
Micro expanded mesh can be used as a speaker cover material. It can be made in different shapes and sizes to match the speakers in a car (door and front speakers). Micro expanded mesh protects driver components and speaker internals from external impacts and foreign objects, reduces ambient noise, and ensures clear sound transmission and playback.

Micro expanded mesh is an important protective material in the air inlet system of automobiles. The precise mesh can filter out debris and small particles to ensure normal airflow. Precision micro expanded mesh can also be used as a protective material, widely used in radiators, brake bushings, and engine air intakes. In addition, it can be used in air intake locations such as bumpers, body kits, fender hood vents, and vehicle openings.
