Automotive & Electronics

The automotive industry emphasizes durability in extreme environments, while the electronics industry focuses more on precision, cleanliness, and electromagnetic shielding. Automobiles are one of the most highly integrated fields of modern sealing technology. A car may use hundreds of seals applied to the powertrain, chassis, body, and electrical systems.

Powertrain system: resistant to high temperature, high pressure, and chemical corrosion

Application scenario: Engine and gearbox

Case: Engine cylinder gasket

Seal type: metal rubber composite gasket.

Function: Located between the engine cylinder block and cylinder head, it is the most important sealing component of the engine. It must seal high-temperature (>150 ° C) and high-pressure combustion gases, while preventing oil and coolant from leaking or leaking out of each other.

Real case: If a certain brand of engine uses inferior cylinder gaskets, they may be "washed out" under high temperature and pressure, causing oil and coolant to mix (producing "oil emulsion"), resulting in engine heat dissipation failure, severe power decline, and even engine scrapping. High performance composite gaskets are the cornerstone of engine reliability.

The electronics industry: a barrier to safeguard precision, purity, and signals

Application scenarios: Smartphones and smartwatches

·Case: Waterproof sealing of smartphones

·Seal type: Micro silicone/thermoplastic polyurethane (TPU) seal ring, waterproof foam, adhesive seal, nano coating.

·Function: Form a sealed network at dozens of points such as SIM card holder, buttons (volume/power), speaker/microphone network, screen and middle frame junction, achieving IP68 waterproof and dustproof rating.

·Real case: The deep waterproof capability of Apple iPhone or Huawei Mate/P flagship phones lies in their precise and complex sealing system. This allows the phone to soak in 1.5 meters of water for 30 minutes without damage, greatly improving the durability and usage scenarios of the product.
