ADVANCING THERMAL AND ACOUSTIC PROTECTION: HOW NEKLAR’S SOLUTIONS FOR COMBUSTION ENGINES ARE DRIVING AUTOMOTIVE PROGRESS

As the automotive industry moves toward innovation and sustainability, managing thermal, acoustic, and electromagnetic challenges in internal combustion engine (ICE) vehicles remains essential. Our solutions, based on high-performance aluminum shielding components, help OEMs and Tier 1 suppliers meet strict protection standards—enhancing vehicle reliability, durability, and overall comfort.

Unlike electrified powertrains, ICE vehicles must address localized high-temperature zones, vibration-prone areas, and increasing noise restrictions. That’s why shielding components are not optional—they’re strategic. Our design process focuses on integrating thermal insulation, acoustic dampening, and EMI mitigation into one unified, robust system that responds to these complex demands.

By adopting this integrated approach, we help manufacturers reduce heat propagation to sensitive areas such as ECUs, passenger cabins, or cable harnesses, while also reducing unwanted noise and vibration. The result: a better driving experience and increased component life cycle.

Simulation-Driven Innovation for Performance You Can Trust

Every solution we develop begins with advanced 3D simulations that allow us to test multiple variables before prototyping. Thermal simulations enable us to optimize shield placement and material conductivity to contain heat exactly where needed. Fatigue and vibration simulations help ensure that the solution will perform under years of real-world use, including high-load or off-road conditions.

NVH (Noise, Vibration, and Harshness) simulations play a vital role in identifying noise paths and treating them with appropriate materials or geometries. Similarly, forming simulations enable us to reduce production errors and material waste during stamping, thus improving both quality and cost-efficiency.

This predictive approach allows us to tailor solutions to a wide range of ICE configurations—from compact city cars to high-performance vehicles and commercial fleets—without compromising performance, cost, or time to market.

Optimized Shielding for Weight, Efficiency, and Versatility

Shielding isn’t just about protection—it’s about efficiency. Our solutions are designed not only to block heat and noise but also to reduce vehicle mass, improving fuel economy and lowering emissions. This is especially important as OEMs continue to push for lower average CO₂ targets.

By using lightweight alloys and optimizing every millimeter of material thickness and geometry, we create components that meet thermal and mechanical goals while minimizing unnecessary bulk. These optimizations are particularly valuable in applications such as underbody exhaust heat shields, turbocharger covers, or firewall panels.

We also offer modular designs that simplify assembly and maintenance, reducing labor costs and allowing greater flexibility on the production line. Customization is at the heart of our service model—we adapt our shielding solutions to each client’s unique specifications and technical targets.

Driving Sustainable Manufacturing Through Technical Excellence

Our solutions are engineered to directly support the automotive industry’s sustainability roadmap. Through lower mass, reduced heat loss, and extended part longevity, they contribute to lower fuel consumption, fewer emissions, and reduced operational costs over time.

Due to our expertise in thermal, acoustic, and electromagnetic shielding, we provide manufacturers with components that comply with the most stringent regulatory and customer-driven requirements. All our solutions are tested under real-life conditions to ensure consistent performance, resistance to corrosion, and environmental stress.

By partnering closely with OEMs and Tier 1 suppliers, we help bridge the gap between technical design and industrial reality. In a sector driven by both tradition and transformation, our solutions enable manufacturers to achieve meaningful gains in comfort, safety, and sustainability.

In conclusion, the role of shielding in ICE vehicles goes far beyond containment. It is a platform for innovation—supporting efficiency, reliability, and forward-looking mobility. With Neklar as a trusted partner, manufacturers are well-equipped to meet today’s challenges and anticipate tomorrow’s demands.
