Sealing strip is a product that seals a thing so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixing. It can be classified according to several methods such as cross-sectional shape, vulcanization method, application location and purpose, and materials used. The following editor of Revolving door seal introduces the classification according to the shape of the section.
Can be divided into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products and other types. Among them, metal rubber composite sealing strips account for more than 60%. The cross-section design is very important for rubber sealing strips. First, the shape and size of the sealing lip are designed. The sealing lips on both sides should contact the glass from both sides of the car window glass with the same and appropriate force. The lip length and thickness should be appropriate. Too thick or too long will increase the resistance of the glass to lift. Too thin or too short will cause the glass to not be well guided and sealed, 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 is 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 take advantage of the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; the last is 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 car body.
