Window Seal Profile Type
May 21, 2018

Seals can be classified into solid core products (circular, square, and flat cross-sectional shapes), hollow products, and metal-rubber composite products. Metal rubber composite seals account for more than 60%. Cross section design is critical for rubber seals. The first is the shape and size of the sealing lip, and the sealing lips on both sides should contact the glass from both sides of the window glass with the same force of the proper size. The length and thickness of the lip should be appropriate. Too thick and too long will increase the resistance of the glass. Too thin or too short will lead to poor guidance and sealing of the glass, resulting in vibration, noise, and leakage of the rain. The shape and size of the bottom of the section are designed. There are projections on the steel channel section of the window. Its function is to assemble the guide channel. Therefore, the bottom of the guide channel section should be designed with a corresponding structure, which is easy to load and can use the elasticity of the sealing strip itself. Adhere to the steel guide groove, to prevent the escape; followed by the shape and size of the outer edge, in order to improve the appearance, the outer surface of the guide groove should be in close contact with the body.
