Prototype and small-scale production of automotive gaskets. Machining of soft materials.

In the automotive industry, gaskets are used in various parts such as engines, transmissions, and bodies, playing a crucial role in maintaining airtightness and liquid tightness while preventing the intrusion of foreign substances. Particularly in environments exposed to high temperatures, high pressures, and vibrations, the durability and reliability of gaskets significantly affect the performance and safety of vehicles. If the material or shape of the gasket is not appropriate, leaks or damage may occur, potentially leading to serious problems. Our company manufactures gaskets tailored to your requirements using soft materials through machining. 【Usage Scenarios】 - Engine head gaskets - Oil pan gaskets - Door seals - Window glass seals 【Benefits of Implementation】 - Ensuring airtightness and liquid tightness - Preventing the intrusion of foreign substances - Improving durability - Extending product lifespan
