First sealing lip shape, dimension design, and on both sides of the sealing lip should be the same, appropriate to the size of the force from the contact with the glass on both sides of the window. Lip length, its thickness should be appropriate, too thick, too long can make glass lifts resistance is big, too thin, too short, lead to glass is not a good guide and seal, vibration and noise, leak phenomenon; Secondly is the cross section at the bottom of the shape, size, design the window slot section steel is convex, its role is to guide assembly, therefore, guide groove profile should be designed at the bottom of the corresponding structure, is easy to load, and can use sealing strip itself elastic attachment within the steel guide groove, prevent its emergence; Finally, is on the outer shape, size, in order to improve the appearance, guide veneer should fit closely with body.
Sealing is an important indicator of quality of motor vehicle, and the index of automotive sealing strip products is the resolution of one of the important parts, it is widely used in automobiles, doors, Windows, front and rear windshield cabin, trunk and other body parts, fill the gap between body parts, shock absorption, waterproof, dustproof, sound insulation, decoration, such as function, for the passenger and vehicle maintenance.
