automotive rubber seal

It can be divided into solid core products (round, square, flat-shaped sectional shape), hollow metal products and rubber and other types of composite articles. Among them, metal rubber composite seal more than 60%. For the rubber seal to said section design is crucial. First sealing lip shape, size, design, lip seals on both sides should be the same size on both sides of the appropriate force from the contact glass window glass. Lip length, thickness should be appropriate, too thick, too long to make the glass lift resistance is too large, too thin, too short will cause the glass to get a good guide and sealing, vibration, noise, leaking phenomenon; followed by cross-sectional shape of the bottom, the design size, the window has a convex cross-section steel channel, its role is to assemble the guide groove, and therefore, the bottom section of the guide groove should design the appropriate structure, both easy to mount, also taking advantage of its own elastic seal attached to the steel guide groove prevent prolapse; and finally take the side of the outer shape, size, in order to improve the appearance of the guide groove, finishes and body should fit closely.

Classified according to the sealing characteristics

It can be divided into the weather seal (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather seal with a hollow tube sponge foam, a better temperature and humidity function. Common weather seal has a door seal, trunk seal, engine cover strips. Common seals generally have around windshield seals and corner window seal, inside and outside bars.

Press rubber composite structure classification

It can be divided into pure rubber seal - constituted by a single plastic types; two composite seal - from the dense foam rubber and sponge rubber composition, often within the dense gel comprising a metal matrix material in the axial direction; three composite seal - It consists of two dense rubber (one of which is light) and the sponge structure, usually within the dense gel comprising a metal skeleton and reinforcing fibers. Four composite seal - Seal Co., Ltd. Shanghai Shen Ya the first in China to develop and produce the composite seal consists of four compounds formed in the cotton gum (bubble pipe) and a surface coated with a thin layer of protection layer of plastic, so as to further improve the service life of the seal.
