The seals are classified according to the shape of the section

    It can be divided into solid core products (round, square, flat cross section shape), hollow products and metal rubber composite products and other types. Among them, metal rubber composite seals accounted for more than 60%. Section design is very important for rubber sealing strip. First of all, seal lip shape, size design, both sides of the sealing lip should be the same size, appropriate force from the window glass on both sides of the contact glass. Lip length, thickness should be appropriate, too thick, too long will make the glass lifting resistance is too large, too thin, too short and will cause the glass is not a good guide and sealing, vibration, noise, leaking phenomenon; second is the shape and size of cross section at the bottom of the design, with a convex window steel groove on the cross section of the in order to guide the assembly, therefore, should be designed to guide section at the bottom of the corresponding structure, can be easily loaded, and can use its own elastic sealing strip attached to the steel guide groove to prevent the extraction; finally the shape and size of the outer edge, in order to improve the appearance of the guide groove surface and the body should be tightly.
