What is NVH?

Noise, Vibration and Harshness (NVH) is used to describe the experience and measurement of unwanted noise, vibration and harshness in various systems and products, particularly in the automotive industry. NVH may arise from factors such as engine operation, road conditions, aerodynamics and mechanical components. Important to product development and design, reducing noise vibration harshness contributes to the enhanced comfort, quality and performance of vehicles and other mechanical systems.

What is a Heat Shield?

A heat shield is a barrier designed to protect certain automobile components from the heat generated by the engine and exhaust system. These shields can consist of different materials depending on whether they are designed to reflect, absorb, or dissipate heat, but ultimately, they all contribute in some way to longer engine life, improved engine performance, and greater operator safety.

ACS’s Patented “One Piece” Isolator

The core function of ACS’s patented One Piece Isolator is to affix a heat shield to various components in the engine compartment or exhaust system (i.e. manifold, turbo-charger, catalytic converter etc.) while adding a layer of NVH protection.

Compressed knitted mesh is able to operate in areas of high temperatures that exceed the range of most elastomers offering superior resiliency and dampening qualities for NVH applications. Historically, heat shield isolator manufacturers would mechanically fasten two washers to each end of a knitted mesh eyelet in order to secure it to the heatshield. Many manufacturers experienced significant problems with these parts falling off in transit, which could erode production efficiency and increase scrap.

Our patented design forms the knitted mesh to the heat shield, making it very hard to remove so that the parts arrive at the place of final assembly intact and ready for use. This level of conformity helps reduce scrap and facilitates automation for our clients and their customers in turn.

ACS also offers a complete array of additional NVH mesh solutions. If you uncover any vibrating parts during a simulation or a durability test, ACS has the perfect mesh component to add to your assembly to reduce noise, enhance comfort, and improve safety.

ACS engineers each of our products to be a perfect fit, not only optimized for final system performance, but also carefully crafted to maximize operational efficiency in your manufacturing process.
