Jun 19, 2017

The sealing strip can be classified according to sectional shape, vulcanization method, use site and use, and materials. According to sectional shape classification: can be divided into solid core products (round, square, flat-shaped section shape), hollow products and metal rubber composite products and other types. Among them, the metal rubber composite sealing strip accounted for more than 60%. The section design is very important for the rubber seals. The first is the sealing lip shape, size design, both sides of the seal lip should be the same, the size of the appropriate force from the side of the window glass contact glass. Lip length, thick should be appropriate, too thick, too long will make the glass lift resistance is large, too thin, too short will lead to a good guide and seal, resulting in vibration, noise, leakage of rain phenomenon; followed by the shape of the bottom section, size design, the window steel Trough section has the bulge, its function is in order to assemble the guide groove, therefore, the Guide trough section bottom should design the corresponding structure, is easy to mount, but also can use the seal itself's elasticity to attach in the steel guide trough, prevents its prolapse; 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.
