Automotive Shielding - Providing Protection with Profitability

Some lesser-known facts-

  • Suffer severe engine damage as a result of engine overheating
  • Engine damage can lead to head gasket failure
  • Cylinder-head can wrap from excess heat
  • The radiated energy of electromagnetic fields can upset or damage the vehicle's electronic systems, including the microprocessors that control important engine functions, such as the ignition control, the fuel injector, and the fuel-pump control.

The method to protect automotive components from damage due to overheating and electromagnetic interference (EMI) using heat-insulating materials as shields, is called automotive shielding.

Need for automotive shielding

Modern Vehicles have inbuilt significant functions and related features such as GPS, infotainment systems, bluetooth, and electric vehicular and self-driving technology. These functionalities and the overall vehicle system are driven by the need to be protected from heat and electromagnetic radiation. Excessive heat generated by the engine and exhaust systems and radio frequency interference (RFI) can damage components and lead to electronic malfunctions in-vehicle equipment and affect mission-critical systems.

Automotive parts that require heat shielding Automotive parts that require EMI shielding
Compartments of combustion engine Console applications
Exhaust Systems Infotainment head unit
Under bonnet Power steering module
Under Chassis Tire pressure monitoring
Turbochargers Electronic braking system

Hence, automotive shields are used to provide protection to the vehicle body and its integrated components for their efficient performance and optimum usage.

Types of automotive shielding

As related above, there are two types of automotive shielding, namely, heat shielding and electromagnetic interference (EMI) shielding.
