The arrangement of the door seals

The arrangement of the door seals are: Door-mounted (fixed seal around the door), body-mounted (fixed on the doorway seal around the skeleton), doors, body double mounting (in and around the door openings around double side are mounted seal).bolt seals

Obviously, doors, body double mounting seal improves the vehicle sealing. Can use different parts, made of a variety of complex cross-sectional shapes. To enhance the sealing effect. Often set in the limousine on three, four seals, install the front pillar and roof side parts of the four re-sealed beam structure. This multi-channel sealing crevices are generally arranged in the front door, in addition to a sealing function, there are auto noise reduction effect.

Some car doorway foamed rubber seal is made with a metal frame and a chucking surface of the plastic parts at the same extrusion. The foam part is used EPDM rubber (EPDM), a density of 0.6 ± 0.18/cm ³, fitted jacket surface of the grip portion is polyvinyl chloride, a hardness of 65 ± 5HS; metal frame materials used for low-carbon cold rolled steel sheet, the surface requirement bright; gripping part of the surface with a pattern, patterns shapes and colors and interior colors and patterns to match, played a role in beautifying the interior.

It is composed of three unequal section of the aluminum composition, so set the door glass in the door seal section is composed of three components ranging

Section of the above three properties of materials are chlorinated polyethylene with rubber (PEC), contact with the glass surface with a flocking, the extrusion section. Requires no less than the whole of the seal 48h, higher than 60 ℃ cases, the installation status (stuffing) allowed the aging pattern, it should be able to withstand continuous partial flocking alternating load wear test, and require nitrogen test 1000 hours of light discoloration allowed, the products, high quality requirements, process more complicated, more difficult, there are certain difficulties in the current domestic production.tamper evident seal
