We’re going to switch gears this week and discuss a topic that is near and dear to some of our readers – thermal management and heat shielding. Sometimes, utilizing a proper construction, your gasket can provide what you need in an application as far as thermal management is concerned. However, other times you will need a formed heat shield.
Similar to the variety you find in gasket materials, you will see that you have choices in what you select for your thermal management/heat shielding needs. One of the top questions that we get asked is “what is the benefit of using an embossed sheet over a flat sheet?” If this is the very reason that you stumbled upon this blog, you’re in luck. Keep reading.
1. Material content
The embossment structure provides 4x the stiffness vs. a flat sheet. This allows a thinner metal to be used to retain the same stiffness, allowing for lighter weight and lower material cost.
The embossment feature provides depth to a 2-dimensional design. As a single-layer, it provides a stand-off from touching surfaces. As a multiple-layer, it provides for an air-gap to prevent layers from full contact.
Embossment provides unlimited design potential. The embossment pattern allows for easier forming than with flat sheets as some forming has already been started across the sheet. It also allows for a smoother transition in forming shapes as the rough corners and problem areas are minimized.
4. Noise reduction
Embossed is quieter than a flat metal shield. The 3-dimensional structure of the embossed sheet helps to disrupt sound waves that are reflected and transmitted. It also provides reduced vibration and reverberation as found with flat sheet designs.
Embossment provides a more uniform appearance across the shield which is more appealing than a flat piece with rough corners. This provides a more professional look.
Take a Look
If you have any questions about embossed sheets and the advantages of working with them, please don’t hesitate to talk to a trusted supplier to learn more. Embossed metal products are designed for forming into heat shields using production tooling or hand-fabrication. Individually sold sheets can be the right solution for you to build a custom formed heat shield made exactly for your application that will provide performance to match even the best production designs.

If embossed metal is what you have been looking for, MTI offers these sheet products in aluminum and stainless steel material options so that prototypes and small quantity pieces can be easily built by hand for validation and product development. We’ll be glad to work with you on this development and can carry it through to a production part as needed.
4 Things to Know About Heat Shields & Thermal Management
Heat has always been an issue in and around engines. Over the last few years, heat has increased significantly in these areas such that engineering teams need to include provisions for thermal management in their designs. If you’re still learning more about this technology, we invite you to continue reading.
Thinking of Using a Gasket To Insulate Against Heat? Here Are 4 Considerations.
Have you ever been in a situation where you are working in a high heat application and you need to figure out a way to insulate against the heat? Gasket materials that have insulative properties can be a perfect fit for your application in so many ways. Keep reading for a list of considerations if you are trying to decide if this would be the answer to your problem.
6 Ways To Make Life Easier If You Work In High Temp Applications
Designing a gasket, selecting your gasket material and sealing your joint sounds like it should be a relatively straightforward thing to do. However, throw a high temp application into the equation, and things can become a bit more challenging. Once you really understand how to deal with high temperature applications and what you need to know to start the process of selecting the right material for these applications, you’ve won half the battle.
