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 modern vehicles, combustion processes and high-performance drive systems generate extreme temperatures — particularly in the engine bay, exhaust system, and other heat-intensive areas. Without effective automotive heat protection, both essential components and passenger comfort can be compromised.Our mission is to develop custom heat shielding solutions precisely tailored to the demands of modern vehicle designs. Our high-quality thermal insulation components significantly reduce heat exposure to sensitive parts, improve thermal efficiency, and enhance the durability of automotive systems.

Common Applications for Our Heat Shielding Solutions:

✔ Engine compartment – Protection against high thermal loads from combustion processes
✔ Firewall insulation – Minimizing heat transfer into the passenger cabin
✔ Exhaust manifold – Shielding from extreme exhaust heat
✔ Exhaust system heat shielding – Reducing radiant heat and thermal stress
✔ Wheel well – Protection from heat generated by braking and suspension systems
✔ Underbody insulation – Effective thermal protection for the floor pan and structural components

Our custom heat shield components are made from high-temperature resistant materials and can be precisely adapted to the specific geometry of vehicle parts. Whether for standard vehicles or special applications – we provide automotive heat protection solutions of the highest quality.

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.
