Automotive

Electromagnetic interference (EMI) is a growing challenge for modern electric vehicles (EVs). As the number of electronic components in vehicles increases, the risk of electromagnetic interactions rises, leading to signal disruptions and malfunctions in sensitive components. Alternatively, the term electromagnetic compatibility (EMC) is used to describe the ability of electronic systems to operate without interference. To ensure the functionality and longevity of electrical vehicle components, we manufacture customized aluminum-formed parts and aluminum composite foils for effective EMI shielding. Our solutions range from small sensor shields to fully enclosed battery boxes, providing reliable protection against electromagnetic interference.

Benefits of Our EMI Shielding for Electric Vehicles:

✔ Effective protection against electromagnetic interference (EMI) – ensures uninterrupted signal transmission
✔ Optimized shielding for battery enclosures & control units – prevents malfunctions in high-voltage systems
✔ Custom aluminum and composite shielding solutions – tailored for every vehicle architecture
✔ High thermal conductivity & stability – ideal for high-performance drivetrain systems
✔ Meets EMC standards for the automotive industry – reliable shielding for modern electric mobility

Our EMI shielding materials are specifically developed to enhance the safety and performance of electric vehicles. They reduce electromagnetic interference, prevent overheating, and support efficient power electronics.

Effective heat protection for vehicles

In vehicles, extreme temperatures arise due to the combustion process and high-performance powertrain systems, particularly in the engine compartment, exhaust system, and other heat-intensive areas. Without effective heat protection, both critical components and passengers can be affected. Our goal is to develop customized heat shielding solutions that meet the demands of modern vehicles. Our high-quality thermal shielding components reduce heat exposure to sensitive parts, enhance thermal efficiency, and extend the lifespan of vehicle systems.

Common Applications for Our Heat Shielding Solutions:

✔ Engine compartment – Protects against extreme heat generated by combustion processes
✔ Firewall – Reduces heat transfer into the vehicle cabin
✔ Exhaust manifold – Shields against high temperatures in exhaust systems
✔ Exhaust system – Minimizes heat radiation & thermal load
✔ Wheel arches – Protects against heat from braking and suspension components
✔ Underbody – Efficient thermal insulation for vehicle floor & chassis

Our customized heat shielding solutions are made from high-performance, heat-resistant materials and can be precisely tailored to specific vehicle components.

In addition to providing heat protection, Braun’s products are also ideal for acoustic insulation in vehicles. Through microperforation technology, sound waves are efficiently redirected to the insulation material, effectively reducing noise levels inside the vehicle and significantly improving driving comfort. Our custom-engineered components are designed for strategic placement in noise-prone vehicle areas, minimizing disruptive sounds and enhancing the vehicle’s acoustic performance.

Common Applications for Our Acoustic Insulation Solutions:

✔ Engine compartment – Reduces engine noise & vibrations
✔ Firewall – Prevents sound transmission into the cabin
✔ Wheel arches – Dampens road & tire noise
✔ Underbody – Absorbs sound for a quieter driving experience
✔ Exhaust system – Minimizes exhaust & airflow noise

At Braun, we offer tailor-made acoustic solutions, adjusting materials and processing techniques to meet specific customer requirements, ensuring optimal sound absorption and noise reduction.
