Automobile rubber seal strip is one of the important parts and components of the automobile. It is widely used in doors, windows, body, seat, skylight, engine case and trunk. It is waterproof, sealed, soundproof, dust-proof, Earthquake, warm and energy conservation of the important role. It must have a strong tensile strength, good flexibility, but also need better resistance to temperature and aging resistance. In order to ensure the tightening of the strip and profile, the cross-sectional structure of the strip must match the profile.
The classification and characteristics of the car seal are as follows: 1. The classification of the seal parts (parts) includes: the engine cover seal (HOOD), can be divided into front, side and rear; door frame seal (DOOR SEAL); front and rear windshield seals (WINDOW SCREEN); side window seal (SIDE WINDOWSEALING); sunroof seal (SUNROOF SEALING); door head seal (PRIMARY DOOR SEAL); window guide groove seal (GLASSRUN (TRUNK SEAL); anti-noise seal (ANTI-NOISE); dust-proof (ANTI-DUST), and so on.
2.According to the shape of the cross-section can be divided into solid products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products and other types. Among them, metal rubber composite seal more than 60%. For the rubber seal section design is essential. The first is to seal the lip shape, size design, both sides of the sealing lip should be the same, the size of the appropriate force from the sides of the window glass contact glass. Lip length, thickness should be appropriate, too thick, too long will make the glass lift resistance is too large, too thin, too short will lead to glass is not a good guide and seal, resulting in vibration, noise, leakage phenomenon; The bottom of the section shape, size design, window steel channel section on the raised, its role is to assemble the guide groove, so the bottom of the guide groove should be designed to the bottom of the corresponding structure, both easy to load, but also the use of the elasticity of the seal itself Attached to the steel guide groove, to prevent its prolapse; Finally, outside the shape of the edge, size, in order to improve the appearance of the outer surface of the groove should be closely fit with the body.
3. According to the sealing characteristics of classification, can be divided into weather seal (WEATHERSTRIP) and general seal (SEALING). Among them, the weather seal with a hollow sponge bubble tube, a better temperature and humidity to maintain the function. Common weather seal with door frame seal, trunk seal, start the machine cover and so on. Commonly used general seal before and after the windshield seal and angle window seal, inside and outside the side and so on.

4.According to the compound structure of rubber compound, can be divided into pure rubber seal - composed of a single plastic; two composite seal - by the dense plastic and foam sponge glue composition, often in the dense plastic inside the direction of the metal Skeleton material; three composite seal - consists of two kinds of dense plastic (one of which is light) and sponge glue composition, usually within the dense plastic containing metal skeleton and reinforcing fiber. Four composite seal - I took the lead in the development and production of the four compounds by the compound of the compound seal, in the rubber (foam) on the surface and covered with a thin layer of protective layer of glue, and further Improve the life of the seal.
5. According to the classification of materials, can be divided into rubber seal; plastic seal; thermoplastic elastomer seal.
6. According to the surface treatment of the classification, part of the surface of the seal can be divided into additional flocking seal; surface coating seal; a fabric paste seal.
7. Special function classification, some seals with electronic intelligent functions, such as anti-pinch seal.
Automotive seal is mainly made by a good elastic and anti-compression deformation, anti-aging, ozone, chemical, wide use of the temperature range -40 degrees centigrade ~ +120 degrees centigrade EPDM rubber (EPDM) rubber foam and dense Composite, containing a unique metal fixture and tongue-shaped buckle, durable, conducive to the installation. Applicable temperature range: PVC material -20 degrees fahrenheit - 150 degrees fahrenheit (-29 degrees centigrade - 65.5 degrees centigrade) EPDM material -40 degrees fahrenheit - 248 degrees fahrenheit (-40 degrees centigrade - 120 degrees centigrade) Internal metal fixture Material: steel wire or steel
