Secret car door seals

Seal used to keep the body door , windows and other moving parts , and front and rear window , triangular windows , which are not part of the dynamic seal , seal shape and cross-section should be used to meet the requirements of different parts and different functions .

The purpose of the sealing strip :
1 , keep the car clean, weatherproof , dustproof , heat insulation, sound insulation ;
2, when the body is subjected to vibration and distortion ,colored cable ties the seal also cushion , shock absorption , keeping the role of glass ;
3 , on the edge of the transfer windows for decoration ;

Sealing strip material, natural rubber is often used to get up early , and later developed into ethylene, propylene rubber, nitrile rubber, synthetic rubber for the mainstream , but also the use of polyvinyl chloride resin. For fixed window edge portion of the front , rear , triangular windows, etc. , there is also a variety of paste forms ( such as direct bonding method or rubber band bonding method ) .

As the synthetic rubber foam should have a good performance , which requires :
1 , excellent weatherability ; 2, for coating with a non -polluting ; 3, a small residual deformation ; 4 , low water absorption ; 5 , can be maintained in good low temperature flexibility ; tamper seal tape 6 , having a heat resistance ; 7 , good wear resistance .

Door seal with the body is a more difficult position, sealing requirements are relatively strict, should be sealed part of a long , cross-sectional shape of the different parts of the seal , and the doors open and close frequently.

Door seals to achieve the basic shape has three sections : curved , compression type, complex . The seal is used in different parts of the shape is much more complex .

The arrangement of the door seals are: door -mounted ( fixed seal around the door ) , body -mounted ( seal fixed on the frame around the doorway ) , doors , body double mount ( around doors and openings around seals are installed on both sides ) .

Obviously , doors , body double sealing strip installed to improve the vehicle sealing, can vary according to the use of the site , made a variety of complex cross-sectional shape , in order to enhance the sealing effect, often set in the limousine three , four seals , before installing pillars and roof side beams parts quadruple seal structure . This multi -channel sealing crevices are generally arranged in the front door , in addition to having a sealing function, as well as car noise canceling effect.
