A gasket is a mechanical seal that fills the gap between two or more mating surfaces, preventing leakage from or into the connected items while they are compressed. It is a deformable substance used to generate and maintain a static seal in a mechanical assembly under varying operating circumstances.
A gasket is a flexible ring or sheet used in static applications to seal joints, flanges, and other mating surfaces to prevent leaking. Gaskets may be manufactured using a variety of ways depending on the material and application.Oil and gas, manufacturing and industrial uses, pulp and paper production, and agricultural equipment all need gaskets and seals.
Gaskets that have become worn or fractured are simple to repair. It is usually suggested to replace gaskets whenever equipment is removed and reinstalled. Gaskets enable less-than-perfect mating surfaces on machine components by filling imperfections. Gaskets are frequently made by cutting sheet materials. Given the possible economic and safety consequences of malfunctioning or leaky gaskets, it is vital to pick the appropriate gasket material for the application.
Seals are utilized between rotating engine parts, pumps, and shafts, whereas gaskets seal a connection between two components or flanges with flat surfaces. Gaskets are utilized to prevent leaks anywhere a union or flange is required. Static seals are the most typical use for gaskets. Many different materials are used to make gaskets.
The most popular rubber or elastomeric materials used to create gaskets include Viton, Neoprene, Nitrile, Pure Gum Rubber, EPDM Butyl, and SBR. When a highly compressible gasket is required, gaskets can be made from a variety of materials such as treated fiber, cork, cork and rubber, non-asbestos, graphite, PTFE, or closed cell sponge. Gaskets are utilized in a variety of sectors such as oil and gas, pulp and paper, power production, and transportation.
Seals must withstand heat, vibration, dust, fluid, and chemical attack for years and tens of thousands of kilometers while being easy to apply during manufacturing and complying with health, safety, and environmental laws.
Sealing a battery pack housing is the most common use in EVs, followed by gasketing for power conversion devices such as inverters, motors, and other components of an electric powertrain.
The primary battery box, module, and cell enclosures, as well as the lines and connectors in fuel cell systems, electrically powered accessories, and the thermal management system supplying the battery, motors, and charging system, must all be sealed.
Thermal management systems sometimes include sophisticated multi-way valves, while conductive cooling matrices must be sealed and cooling plates attached to cells using heat-conducting materials. Safety-related systems that frequently use hydraulics, such as brakes and ride control systems, also require sealing and sometimes incorporate pumps that create substantial levels of pressure, which can be difficult for seals to withstand.
The Global EV High-Voltage Sealing Gasket Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Freudenberg Sealing Technologies is helping to make electric car production more cost-effective by developing a new seal for traction-battery housings. The company’s unique Profiles-to-Gasket, or P2G, approach was created specifically for annual manufacturing runs.
Seals produced using the P2G technique augment those that have previously been designed primarily for high-volume manufacture. An electric vehicle’s traction battery is its heart. Even in long-term operation, it is critical to preserve its high-voltage components from moisture and dirt.
At the same time, battery housings must be accessible for maintenance. As a result, manufacturers are favoring housings with a wide cover that offers easy access to all components.
When the lid is closed, Freudenberg Sealing Technologies supplies profiled flat gaskets to ensure perfect impermeability. Lithium-ion batteries outfitted in this manner, for example, have proven themselves in the Renault Zoe.
However, the cross-section and size of such seals must be precisely tailored to a certain battery. Changes are impossible to make without creating a new tool. The expenditure of purchasing such a gadget is mostly repaid in increased quantities.
As a result, straight sealing profiles are used for extremely limited production runs, such as prototype manufacturing. Their lengths can be manually trimmed. They are joined together with unique corner parts, allowing them to cover any house shape.
A solution satisfying these objectives is now accessible thanks to the Profile-to-Gasket, or P2G, idea. The two essential roles of sealing and fastening are done in distinct portions of the sealing profile in this innovative housing seal. In this method, a compressible hollow profile on the seal’s exterior side ensures that no fluids or particles enter the housing.
This hollow shape also ensures the essential tolerance compensation in a housing seal. A fixation strip on the inside side can be used to secure the seal to the housing. The design allows the P2G seal to be manufactured as an unending band and then trimmed to the desired length in each instance.
