Sealing strips are classified by section shape
The sealing strip can be divided into solid core products (round, square, flat section shape), hollow products and metal rubber composite products. Among them, the metal rubber composite sealing strip accounts for more than 60%. Section design is critical for rubber seals. The first is the shape and size of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same appropriate size and force. The length and thickness of the lip should be appropriate. If the thickness is too thick or too long, the resistance of the glass will be too large. If it is too thin or too short, the glass will not be well guided and sealed, resulting in vibration, noise and leakage. The shape and size of the bottom of the section are designed. There is a convexity on the section of the steel groove of the window. The function is to assemble the guide groove. Therefore, the bottom of the section of the guide groove should be designed with corresponding structure, which is easy to install and can utilize the elasticity of the seal itself. It is attached to the steel guide groove to prevent it from coming out; finally, the shape and size of the outer lap, in order to improve the appearance, the outer surface of the guide groove should be closely fitted with the body.
