Sealing and Pipe Technology in the Automotive Industry: The Key Role of Rubber Extrusions

Seals: The "Invisible Guardian" Guarding the Interior of the Car
Solid rubber extrusions are the preferred material for automotive seals due to their excellent elasticity, wear resistance and aging resistance. In automotive design, sealing is directly related to the comfort, noise control and environmental adaptability of the vehicle. For example, door seals and window seals, which seem inconspicuous, actually have multiple tasks such as preventing rainwater from leaking, blocking dust from entering, and reducing wind noise.

Door seals are usually installed on the edge of the door and fit tightly with the door frame of the vehicle body to form an effective barrier. They not only need to maintain good elastic recovery when opening and closing the door to ensure that the sealing effect is not weakened due to long-term use, but also need to withstand extreme temperature changes and maintain material stability. The window seal is designed around the edge of the window glass to ensure that there is no air or water leakage during the glass lifting process, while reducing wind noise during driving and improving the driving experience.

The reason why solid rubber extrusions can meet these stringent requirements is due to their customized production capabilities. Manufacturers can adjust the rubber formula and optimize the extrusion process according to the specific needs of different models and parts to achieve the best sealing effect and durability. In addition, the application of environmentally friendly rubber materials is also in line with the current automotive industry's pursuit of sustainable development.

Pipeline: The "blood channel" of the automotive system
In the complex internal structure of the car, the pipeline system is like the vascular network of the human body, responsible for transporting key media such as coolant, fuel, brake fluid, etc., to ensure the normal operation of key functions such as engine cooling, fuel supply, and brake system. As the core component of this system, the performance of solid rubber hose is directly related to the safety and reliability of the car.

Coolant hoses need to withstand high temperature and high pressure working environments, and have good corrosion resistance to prevent engine overheating caused by coolant leakage. Fuel hoses require higher oil resistance, permeability resistance and flame retardancy to ensure that fuel is efficiently and safely delivered to the engine. These hoses are usually designed with a multi-layer structure, with the inner layer directly contacting the medium, the outer layer providing protection and wear resistance, and the middle layer may be added with reinforcing fibers to improve the overall strength and pressure resistance.

With the advancement of automotive technology, especially the rise of electric and hybrid vehicles, the requirements for pipeline systems are also increasing. For example, the protective cover of the high-voltage wire harness also needs to be made of high-performance rubber materials to ensure efficient and safe connection between the battery pack and the motor of the electric vehicle.
