There are several categories of the classification of automobile sealing strips.

    1. the name classification according to the sealing section (part) includes: engine cover seal (HOOD), and can be divided into front, side and rear; door frame seal (DOOR SEAL); front and rear windwindow seal (WINDOW SCREEN); side window seal (SIDE WINDOWSEALING); skylight seal (SUNROOF SEALING); door seal (PRIMAR); door seal (PRIMAR) Y DOOR SEAL); window guide groove seal (GLASSRUN CHANNEL); outer side strip (water cut) (WAISTLINE); luggage seal (TRUNK SEAL); anti noise seal (ANTI-NOISE); dustproof bar (ANTI-DUST), etc.

    2. According to the section shape, it can be divided into solid core products (round, square, flat section shape), hollow products and metal rubber composite products. Among them, metal rubber composite seal accounted for more than 60%. Section design is very important for rubber seals. First of all, the shape and dimension of the sealing lip should be designed. Both sides of the sealing lip should contact the glass from both sides of the window glass with the same force and appropriate size. The length and thickness of the lip should be appropriate, too thick and too long will make the glass lifting resistance larger, too thin and too short will cause the glass to not get good guidance and seal, and produce vibration, noise, rain leakage; secondly, the shape of the bottom of the section, the size design, the section of the window steel groove is convex, its function is to assemble the guide groove. Therefore, a corresponding structure should be designed at the bottom of the guide groove, which is easy to load and can be attached to the steel guide slot with the elasticity of the seal itself. Finally, it is the shape and size of the outer edge. In order to improve the appearance, the outer face of the guide groove should be closely fitted with the body.

    3. according to the sealing characteristics, it can be divided into weather sealing strip (WEATHERSTRIP) and general seal strip (SEALING). The weather sealing strip has hollow sponge foam tube and has better temperature and humidity maintenance function. Commonly used weather seals include door frame seals, luggage compartment seals, engine case covers, etc. Commonly used sealing strips include front and rear windshield seals, corner window seals, inner and outer side bars, etc.

    4. classified according to the compound structure of the adhesive, it can be divided into pure glue seal - made up of single glue; two compound seal - composed of dense glue and foam sponge, often contains metal skeleton material in the axial direction of dense glue, and three compound sealing strip is made up of two kinds of dense glue (one of which is light color) and sponge glue Usually, there are metal skeletons and reinforcing fibers inside the dense glue. Four compound sealing strip, Shanghai Shen Ya sealing parts Co., Ltd. has taken the lead in developing and producing a composite sealing strip made up of 4 kinds of glue in China, and covered a thin layer of protective coating on the surface of the rubber (bubble tube), so as to further improve the life of the seal.

    5. according to the classification of materials, it can be divided into rubber sealing strips, plastic sealing strips and thermoplastic elastomers sealing strips.

    6. according to the classification of surface treatment state, the surface of some seals can be treated with additional processing, which can be divided into flocking seals, surface coating seals, and fabric sealing strips.

    7. special function classification, some seals have electronic intelligent functions, such as anti clamping, sealing strips, etc.
