Micro Expanded Metal for Automotive Manufacturing
During automotive manufacturing, the auto spare parts is critical to whole automotive performance. Even the small bearing can affect the customer experience feeling and car service life.
Micro expanded metals are widely used in Automotive manufacturing and aftermarket. The micro expanded metal has versatile choice and configuration variability to be used as supporting material, protective material and lubricating material and filter screens to enhance automotive performance and extend spare part service life.
“Compare to the typical extruded material, sintered material or woven material, the expanded metal adopts unique slit and stretch technology, which is no waste material and will not unravel during processing to make it be economical and cost-effective alternative choice. Additional, wide ranges of opening, structures (2D or 3D structure), thickness, open areas configurations make it possible to be used more applications”.
Airbag Filter Screen
The airbag is an important component of a motor vehicle’s occupant resistant system. The micro expanded metal as the support and filter material can guarantee operational reliability in fluctuating conditions and compensate for thermal expansion in the airbag. it also performs the functions of heat dissipation, filtration and flow distribution.
The micro expanded metal airbag filter screen is widely used in driver, front-passenger, back seat, head, side, knee and seat belt airbags.
PEMPL expanded metals and foils are available in a wider range of widths, thicknesses, and open area configurations than any other material type. This combined with the ability to perform custom slitting and edge treatments makes PEMPL the premier supplier for airbag filter materials.

PEMPL Micro Expanded Metal for Automotive Bushing
Bushing
The current generation of bushing is designed for higher duty and heavier suspension components on cars, light trucks, and off-road equipment and utilize an aluminium or steel backing material in addition to an improved expanded phosphor bronze support structure for the PTFE. The performance gains utilizing an expanded product have made it the material of choice with engineers and the majority of the new bushings being designed will utilize an expanded product. Currently, there are some new model cars with over 200 bushings and this number will continue to increase as these low friction, oil-less bushings are utilized in every moving part within the automobile. Additional applications for these bushings include motorcycles, off-road equipment, bicycles, and even appliances.
The phosphor bronze micro expanded metal is used as the support structure of PTFE and then added with the aluminium or steel backing material to form the current bushing. This type of bushing is low friction, oil-less and can withstand extreme load and continual abuse and can be used in every moving part within the automobile. Additionally, it is widely used in the trunk, hood hinges, seat backs, door hinges and light suspension components for higher dusty and heavier suspension components on light trucks and off-road equipment.
