Custom-shaped sealing strips, with their unique shapes and tailored dimensions, have become indispensable sealing solutions across numerous fields. In the construction industry, custom-shaped sealing strips are widely used for waterproofing and dustproof sealing in doors, windows, walls, and other parts, ensuring the airtightness and watertightness of buildings. In automobile manufacturing, they are applied to the sealing of car doors, windows, and other parts, effectively isolating noise and dust, thereby enhancing driving and riding comfort. Furthermore, in industries such as electronic equipment manufacturing and machinery manufacturing, custom-shaped sealing strips are also widely used for sealing and protection due to their excellent heat resistance and aging resistance. The extensive application of custom-shaped sealing strips not only improves production efficiency across various industries but also guarantees product stability and durability, making them an indispensable key component in modern industrial manufacturing.
