What components are usually protected by liquid silicone encapsulation technology for automotive spare parts?

Liquid silicone rubber (LSR) is a high-performance elastomer material with excellent elasticity, resistance to high and low temperatures, chemical corrosion, electrical insulation, and other characteristics. In the automotive industry, the liquid silicone encapsulation process is mainly used to protect and enhance the performance of some key components. The following are some common applications:
Sensors: such as tire pressure sensors, temperature sensors, etc., liquid silicone can provide sealing and protection, preventing moisture and chemical corrosion.
Electronic control unit: Electronic components such as the ECU (electronic control unit) of a car, with liquid silicone used for sealing to prevent dust, moisture, and other intrusion.
Lamp components: such as the sealing of headlights and taillights, liquid silicone can provide good sealing performance, preventing the invasion of water vapor and dirt.
Cables and connectors: Protect cables and connectors from environmental factors and extend their service life.
Engine components such as ignition coils, fuel injectors, etc., liquid silicone can provide protection against high temperature and chemical corrosion.
Interior parts: For example, some car buttons, handles, decorative parts, etc., liquid silicone can provide a soft touch and durability.
Seals: Used as sealing strips for doors, windows, engine hood, luggage compartment lid, etc., providing good sealing performance.
Shock absorption and cushioning components: In car suspension systems and chassis, liquid silicone is used to absorb vibrations and impacts.
Air filtration system: such as the sealing components of an air filter.
Power transmission system: protection of components such as transmission belts and gears.
The encapsulation process of liquid silicone is also widely used in other automotive components that require sealing, protection, shock absorption, and insulation. Due to its high temperature resistance, low temperature resistance, and chemical corrosion resistance, liquid silicone has become an ideal choice for automotive component protection.

It is worth mentioning that the liquid silicone encapsulation process not only has excellent performance characteristics, but also has the advantages of efficient and high-precision production. Liquid silicone materials have a shorter curing time, which greatly shortens the production cycle of products and improves production efficiency. Meanwhile, a precise injection control system ensures precise coating of silicone materials, avoiding material waste and defects.
The liquid silicone encapsulation process plays an important role in the manufacturing of automotive parts, and its protected components cover multiple aspects such as engine components, electrical components, and seals. This process not only improves the performance and reliability of automotive parts, but also provides strong guarantees for the safety and comfort of vehicles.
