Key applications of other screws in automotive interior assembly
In automobile manufacturing, interior assembly is a vital part, which directly affects the comfort, aesthetics and stability of various components in the car. In this field, screws, especially various types of "other screws", such as expansion screws and wood screws, play an extremely important role. Companies represented by Yuyao Cili Machinery Co., Ltd. have accumulated rich experience in the design and production of self-drilling screws and related products, and are committed to providing high-quality fastening solutions for automotive interior assembly.
Automobile interiors involve multiple assembly parts, including dashboards, seats, door inner panels, center consoles, roof linings, etc. These assemblies not only need to ensure the firmness of the structure, but also need to meet the requirements of visual beauty, easy installation, long-term stability, etc. Therefore, screws for automotive interior assembly need to have the following characteristics:
Firmness: Interior parts must withstand long-term vibration, temperature changes and humidity environments, and screws must provide strong fastening force to ensure that the assembled parts will not loosen.
Anti-loosening design: Due to the frequent vibration during driving, the screws need to be designed into an anti-loosening structure to ensure that they will not loosen after long-term use.
Anti-corrosion: Although the interior environment of the car is relatively closed, changes in temperature and humidity may still cause metal fasteners to rust, so the screws need to have a good anti-corrosion coating or material.
Easy installation: In the production of automobile assembly lines, assembly efficiency is crucial, and the screw design needs to be easy to assemble and disassemble to reduce production time and cost.
Light weight: Modern cars have increasingly higher requirements for lightweight, and the weight of the screws directly affects the weight of the entire vehicle. Therefore, interior screws often need to reduce weight as much as possible while ensuring strength.
For example, window expansion screws are mainly used for fixing and supporting structures in automobile interiors, especially in the joints between fixed plastics or other materials and metal frames. This type of screw is particularly prominent in the following parts:
Skylight frame assembly: The fixing of the skylight requires stronger screws to ensure stability under vibration and temperature changes. Through its expansion characteristics, the expansion screw can effectively fill the gap when tightening, enhance the firmness of the connection part, and prevent the skylight from leaking or loosening.
Window frames: Window interior frames usually require the combination of plastic and metal. Expansion screws can achieve a tight fit through expansion, provide strong shock resistance, and ensure the stability of the window frames in long-term use.
Advantages:
Expansion design increases fastening force: When the screws are tightened, the expansion part will expand, ensuring a more secure fixation in soft or porous materials.
Good vibration resistance: Expansion screws can better withstand the vibrations generated by the vehicle during driving, ensuring that interior parts will not loosen.
Wide applicability: Expansion screws are suitable for the combination of various materials, especially for windows and frame assembly that require precise installation.
