Classification Of Automobile Sealing Strips

1. Classified according to the name of the sealing strip installation part (part)
Engine cover sealing strip (HOOD), which can be divided into front, side and rear; door frame sealing strip (DOOR SEAL); front and rear windshield sealing strip (WINDOW SCREEN); side window sealing strip (SIDE WINDOWSEALING); Sunroof sealing strip (SUNROOF SEALING); door head seal strip (PRIMARY DOOR SEAL); window channel sealing strip (GLASSRUN CHANNEL); inner and outer strips (water cut) (WAISTLINE); trunk sealing strip (TRUNK SEAL); anti-noise Sealing strip (ANTI-NOISE); dustproof strip (ANTI-DUST), etc.
2. Classified by section shape
It can be divided into solid products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strip accounts for more than 60%. Sectional design is very important for rubber sealing strips. The first is the shape and size design of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. The length and thickness of the lip should be appropriate. If it is too thick or too long, the lifting resistance of the glass will be too large. If it is too thin or too short, the glass will not be guided and sealed well, resulting in vibration, noise, and rain leakage; the second is The shape and size of the bottom of the section are designed. There are protrusions on the section of the window steel channel, which are used to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can use the elasticity of the sealing strip itself. Attached to the steel guide groove to prevent it from falling out; finally, the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely attached to the vehicle body.
3. Classified by sealing characteristics
It can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather sealing strip has a hollow sponge foam tube, which has a good temperature and humidity maintenance function. Common weather sealing strips include door frame sealing strips, trunk sealing strips, engine box cover strips, etc. Commonly used general sealing strips include front and rear windshield sealing strips, corner window sealing strips, inner and outer side strips, etc.
4. Classified according to the composite structure of rubber materials
It can be divided into pure rubber sealing strip - composed of a single rubber type; two composite sealing strips - composed of compact rubber and foamed sponge rubber, often containing metal skeleton materials in the axial direction inside the compact rubber; three composite sealing strips - It is composed of two kinds of compact glue (one of which is light-colored) and sponge glue, and usually contains metal skeleton and reinforcing fibers inside the compact glue. Four composite sealing strips——Shanghai Shenya Sealing Co., Ltd. took the lead in developing and producing composite sealing strips composed of four kinds of rubber materials in China. Layer glue, thus further improving the service life of the seal.
5. Classification by material type
Can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips.
Classification by surface treatment status
The surface of some sealing strips has been additionally treated, and can be divided into flocking sealing strips; surface coating sealing strips; fabric patching sealing strips
6. Classified by special function
Some sealing strips have electronic smart functions, such as anti-pinch sealing strips and so on.
