What is the classification of the sealing strip according to the shape of the section

It can be divided into solid core products (round, square, flat section shape), hollow products and metal rubber composite products and other types.

Among them, metal rubber composite sealing strip accounted for more than 60%. For rubber seal section design is very important.

The first is the shape and size of the sealing lip design, both sides of the sealing lip should be the same, the size of the appropriate force from both sides of the window glass contact glass. Lip length, thickness and thickness should be appropriate, too thick, too long will make glass lifting resistance is too large, too thin, too short and can lead to glass can not get good guidance and sealing, vibration, noise, leakage phenomenon; Secondly, the shape and size of the section bottom design, the window steel groove section has a convex, its role is to assemble the guide groove, therefore, the guide groove section bottom should be designed with the corresponding structure, which is easy to load, and can use the elastic adhesion of the sealing strip itself in the steel guide groove, to prevent it from coming out; Then the shape and size of the outer edge. In order to improve the appearance, the outer veneers of the guide groove should be closely fitted with the body.
